SCORES & OUTDOORS: Banded longhorn beetles common in central Maine

Banded longhorn beetle

Roland D. Halleeby Roland D. Hallee

A little while back, while we were sitting with neighbors at camp, we noticed a bug walking along the floor of the porch. Strange looking thing…really ugly! They asked what it was. That was easy.

It was a longhorn beetle.

Although you don’t see them often, they are pretty common around the world, including Maine. Oh, I forgot. They are called banded longhorn beetles. There are over 20,000 species worldwide, 1,200 of which occur in North America.

Adult longhorn beetles, Typocerus velutinus, vary greatly in shape, size and color. In general, they are cylindrical and rather long-bodied. Some of the larger ones can reach six inches in length, but most species measure around two to three inches long. Some are dull brown, while others have bright colors or intricate patterns on their wing covers.

But the dominant part of their bodies are their antennae. They can reach at least two-thirds as long as the body, and in some species the antennae are longer than the body. Males have longer antennae than females. Some are slow moving, while others can run quickly or are strong fliers. Depending on the species, adults may be observed feeding on flower parts, leaves or bark.

Banded Longhorn Beetles have extremely long antennae (horns) like their other relatives. Their bodies are colored in alternating bands of red and yellow. The head and pronotum are black. A thin band of yellow separates the pronotum from the head and abdomen. They are wider at the ‘shoulders’ and taper at the tip of the abdomen. Antennae are black and segmented. Legs are yellow with black ‘feet’.

They are often found on flowers, eating the pollen of a variety of species though they seem to favor parsley, carrot and celery flowers. Look for them in herb, vegetable, and flower gardens. Adult beetles can also be found on hardwood trees. Eggs are laid on dead or decaying trees where larvae hatch and begin boring into the wood. Look for larval frass, a mix of feces and sawdust, on the trunk or near the base of the tree. It is produced as a larva digs and is expelled as the tunneling deepens. This species’ larvae seem to prefer birch, sumac and goldenrod. Examine fallen trees and rotting logs in mixed wood forests for signs of the Banded Longhorn Beetle.

Longhorn beetles have many natural enemies, especially parasitic wasps and the larvae of certain other beetles. Many birds feed on adults and woodpeckers are fond of the larvae. Lizards sometimes lie in wait and capture adults when the beetles land on bark to mate or lay eggs.

Adults can be found on hardwood trees. Eggs are laid on the dead or decaying trees where lavae hatch, boring into the wood. Look for larval frass, a mix of feces and sawdust created when the larva tunnels deeper. This species seems to prefer birch, sumac and goldenrod, of which there are plenty in central Maine. They can be found in 38 states, seven Canadian provinces, mostly in eastern Canada, and Mexico.

Partly because of their relatively slow rate of reproduction, the survival of some species of longhorn beetles is endangered. For example, the valley elderberry longhorn beetle is threatened with extinction in California. Development and farming along river banks have destroyed much of this beetle’s natural habitat.

And then, you have the Asian longhorn beetle, which have become a serious threat to some of North America’s most beautiful and popular trees. Native to parts of Asia, the beetle is believed to have arrived in North America in the wooden packing material used in cargo shipments from China. Isolated Asian Longhorn Beetle infestations have been discovered in Brooklyn and Amityville, New York, and in Chicago, Illinois. In all instances where Asian longhorn beetles have been found, authorities have reacted quickly to stop the infestation from spreading.

Trees favored by the Asian longhorn beetle are predominantly maples, but infestations have also been discovered in horse chestnuts, poplars, willows, elms, mulberries and black locusts. Currently, there are no known chemical or biological defense against the Asian longhorn beetle and, in North America, they have few natural predators. In all cases of infestation, the affected trees are cut down and the wood destroyed.

In concluding, if you see a banded longhorn beetle, they are scary looking, but quite harmless to humans.

SCORES & OUTDOORS: Turtles are laying their eggs: please use caution when approaching

Roland D. Halleeby Roland D. Hallee

“It’s that time of year, again.” Probably one of the most over used phrases in the English language, and one that I loathe to hear. Why? Because when you come right down to it, everyday is that time of year for something. Anyway, here we go.

It’s that time of the year again when snapping turtles appear everywhere to lay their eggs. Just this past week I have seen at least a half dozen snappers on the side of the road; saw one person stop to help it across the road, and I myself have done it once on the Nelson Road, in Vassalboro.

And, two concientious young citizens, Bella and Sophie Lefferts, have created and placed signs along a stretch of Village Street, in South China, proclaiming, “Take it Slow, Turtles Crossing.”

Snapping turtles, Chelydra s. serpentina, range across the eastern United States to the Rocky Mountains, from southern Canada to the Gulf of Mexico, and into Central America.

common snapping turtle

The snapping turtle can be easily recognized by its dark upper shell with a deeply serrated back margin, and a small bottom shell that does not completely cover all of the animal’s flesh. The upper shell can measure between 8 – 12 inches in length on average in adults, and it can weigh between 10-35 pounds. These turtles have long tails, often measuring as long or longer than the shell, and is covered with bony plates. They also have a large head, long neck, and a sharp, hooked upper jaw. This hard beak has a rough cutting edge that is used for tearing food.

Once turtles mature and their shell hardens, they are virtually predator-free.

If you see a snapping turtle crossing the road, and decide to help it out, always make sure you relocate it on the side of the road in which it was headed. If not, it will only try to cross the road again. It’s obviously headed in a direction that is important to it. Always use caution when picking one up. Place your thumbs in the center of the upper shell, and the rest of your hand on its stomach. Be careful not to make contact with its mouth. It could be painfully uncomfortable if it were to bite you.

Never use a broom or shovel to help it along, as you could injure the turtle.

The female turtle will lay eggs in sandy, soft soil between April and November, depending on its location. In our area, they usually lay their eggs in May and June. That is why the shoulder of a road looks inviting to them. Be on the lookout, and try to avoid the nest. The female will generally lay between 10 and 50 eggs, and they take three to four months to hatch. Interestingly, eggs incubated at 68 degrees will produce only females; eggs maintained at 70-72 degrees will produce both male and female and those incubated at 73-75 degrees produce only males.

The female will dig a nest, lay the eggs, using her back feet to position them, and then bury the clutch. That makes the nest extremely vulnerable, and is usually a target for raccoons who consider the turtle eggs a delicacy. Skunks, crows, dogs and other mammals are also culprits. It is estimated that up to 90 percent of the nests are destroyed by predators. Countless turtles are also killed or injured on roads during their terrestrial treks. Despite this high rate of mortality, snapping turtles are not endangered, although some states have placed a ban on harvesting them.

The Maine Department of Inland Fisheries and Wildlife (MDIF&W) has voted to outlaw the commercial harvest of snapping turtles. It was urged by then-Commissioner Lee Perry to support the ban, to ensure the sustainability of snappers, which don’t breed until 20 years of age in the north. “While I have no reason to believe that snapping turtles are threatened with extinction in Maine, there is reason to be concerned about the viability of the population,” he said.

Snapping turtles typically live until between 20 and 50 years of age in captivity, although records are poor as to the actual longevity of turtles in the wild. Some studies have indicated that snapping turtles can live well over 100 years.

However, turtles are not innocent victims. They may cause depredation at privately-owned ponds, fish farms, or waterfowl sanctuaries and control methods may be warranted. They will feed on plants, insects, spiders, worms, fish, frogs, small turtles, snakes, birds, crayfish, small mammals and carrion.

It’s important to be on the lookout for turtles this time of year. By driving defensively and keeping alert to conditions on the road, motorists should be able to avoid hitting a turtle.

Have you ever heard the riddle, “If a turtles leaves its shell, is it naked or homeless?”

Well, the answer is: it is not possible for a turtle to “lose” its shell. Their shell is part of them just as much as our skeleton is a part of us. The turtle is connected to its shell through its nerves, skin, ribs, and spinal cord.

I guess you learn something everyday.

SCORES & OUTDOORS – Slugs: what are they good for in the realm of things?

Slugs

Roland D. Halleeby Roland D. Hallee

Slugs! They have been raising havoc with my tomatoes, turnip green and even marigolds. Last year they were responsible for the complete destruction of my cucumber, green pepper and marigold plantings at camp. There seems to be no end to them. That raised the question: what are slugs, what are their usefulness and how do we get rid of them?

First of all, let’s find out a little bit about them.

Slug is a common non-scientific word, which is often applied to any gastropod mollusc, and the word “slug” is more frequently encountered as applied to air-breathing land species, including a few agricultural and horticultural pest species.

Land slugs, like all other slow-moving gastropods, undergo torsion (a 180-degree twisting of the internal organs) during development. Internally the anatomy of a slug clearly shows the effects of this rotation, but externally the bodies of slugs appear rather symmetrical.

The soft, slimy bodies of slugs are prone to dry up (desiccation), so land-living slugs are confined to moist environments and are forced to retreat to damp hiding places when the weather is dry.

Like other snails, a slug moves by rhythmic waves of muscular contraction on the underside of its foot. It simultaneously secretes a layer of mucus on which it travels, which helps prevent damage to the tissues of the foot.

Slugs produce two types of mucus: one which is thin and watery, and another which is thick and sticky. Both kinds of mucus are hygroscopic (absorb and retain moisture). The thin mucus is spread out from the center of the foot to the edges, whereas the thick mucus spreads out from front to back. They also produce thick mucus which coats the whole body of the animal.

Slugs’ bodies are made up mostly of water, and without a full-sized shell to retreat into, their soft tissues are prone to desiccation.

Slugs are hermaphrodites, having both female and male reproductive organs. After mating, the slugs lay around 30 eggs in a hole in the ground, or beneath the cover of objects such as fallen logs.

Mostly, slugs are harmless to humans and to their interests, except for a small number of species of slugs that are great pests of agriculture and horticulture. They feed on fruits and vegetables prior to harvest, making holes in the crop, which can make individual items unsuitable to sell for aesthetic reasons, and which can make the crop more susceptible to rot and disease.

I don’t know if you’ve noticed, but so far I haven’t mentioned any benefits to the ecosystem. Their only contribution seems to be the fact they eat dead leaves, fungus and decaying vegetable material. It has always been my belief that if you allowed those to decompose, they will turn to dirt. Why do the slugs have to eat them?

Frogs, toads, snakes, hedgehogs, salamanders, eastern box turtles and certain birds and beetles are slug predators. Birds include blackbirds, crows, ducks, jays, owls, robins, seagulls, starlings and thrushes. With the large number of crows we have around our camp, I can’t figure out why they haven’t wiped out the slug population.

I also have seen numerous frogs and toads in my garden which might be helping with the fact that the slugs have not attacked my tomatoes. Snakes, which are a no-no as far as I’m concerned are allowed to stay. However, those sightings have been few and far in between, partly due, I think, to the large number of raptors in the area.

So, as you can see, slugs are a pest, they are disgusting, and they serve very little purpose in our environs.

Here are a few general tips on how to deal with slugs:

  • Seedling protection: Protect your seedlings with 2-3 liter plastic soda bottles. Make sure no slugs are around the seedlings first. Cut the bottoms out of the bottles, sink them into the soil around the seedlings and remove the caps. You can reuse them over and over.
  • Mulch: Keep mulch pulled away from the base of your plants. Consider waiting to apply mulch until the soil temperatures have warmed to above 75°F.
  • Garden debris: Keep all decaying matter cleaned out of your garden beds. Clear all dead leaves and debris from the garden on a regular basis and put it in the compost pile which is best located in an area away from the garden.
  • Slug havens: The shaded areas beneath decks can be a slug arena. Keep them weed and litter free.
    You can also build barriers around your garden:
  • Use cedar, oak bark chips or gravel chips which will irritate and dehydrate them.
  • Try a barrier line or an overall sprinkle of powdered ginger.
  • Use wood ashes as a barrier around plants, however try not to let the plant come into contact with the ashes. The ashes act as a desiccant and dry up the slugs.
  • Spread well crushed eggshells around the plants. The calcium released from the eggshells is an extra benefit that “sweetens” the soil. The sharp edges of the shells will kill slugs.
  • Talcum powder works as a barrier but must be replenished after rainfall or watering.
    Finally, there is always the slug trap method:
  • Beer or yeast traps: A traditional trap that seems to work well is to place containers of beer or yeast and water at one inch above the ground level in the garden to entice and drown your prey. Empty traps as needed. For the yeast trap, use one package of yeast to 8 ounces of water.
  • Grape juice: A new rendition on the beer trap is to use grape juice. For some reason slugs really have a taste for this. Use just as you would in the beer method and buy the cheapest grape juice you can find.
  • Beer batter bait: Mix 2 tablespoons of flour with enough beer to make a thick batter. Put 1 teaspoon of this in a small paper cup and lay the cups on their sides around your plants. Slugs will flock to this, get snared in the flour and die. When the trap is full toss the whole thing in the compost pile.
  • Comfrey: This perennial is a preference of slugs and can be used as a trap. Comfrey is considered to be an invasive plant, however, it has so many uses for the garden and medicinally that it is worth having around. Comfrey has more protein in its leaves than any other vegetable, perhaps explaining its appeal to slugs.

I have comfrey around my garden at home and have had very little problems with slugs. So, I might just transplant some to the garden at camp.

Taking into consideration everything we have learned about slugs, the more I think about it, slugs remind me of college students: They suck up available resources, give very little in return, and they like to drink beer. They even prefer the same beers (a study conducted by students at Colorado State University concluded that the slug’s favorite beers are Budweiser products).

SCORES & OUTDOORS: Immature bald eagles sometimes mistaken for golden eagles

Bald eagle, left, and golden eagle.

Roland D. Halleeby Roland D. Hallee

Sitting with friends around a camp fire a while back, one of the neighbors said, that while kayaking that afternoon, she had seen a Golden eagle. I immediately chimed in that they were an endangered species, and were not known to exist in Maine (according to something I had read years ago).

The following day, while taking a boat ride around Webber Pond with some friends who are year-round residents on the pond, he asked if we had seen the Golden eagles. That did it.

Was it possible for Golden eagles to exist on Webber Pond. My friend went on to say he had witnessed them on the ice during the winter, actually devouring some fish that had been left on the ice by fishermen.

To prove his point, he steered the party boat toward the west shore of Webber Pond, where, high in the top of a tree, was this large nest, occupied by some rather large birds. We were not able to discern what was occupying the nest from that distance. Bald eagles were circling in the area. I was still not sold.

Well, research taught me that Golden eagles, one of the largest and fastest of raptors in North America, do exist in Maine, although a rarity, mainly to the west and north of Moosehead Lake. So, now are they moving east in our state? Maine hosts golden eagles in all seasons, but is currently on the edge of both the breeding and wintering range in the East. Most migrants in the East pass west of Maine. Very few golden eagles are in the state at any time of year.

Golden eagles, Equila chrysaetos, can be found throughout the northern hemisphere. A large population exists in the western Rockies and north into Alaska. In the east, a small breeding population occurs in Maine, Labrador and Québec Province, although its range is greatly reduced from its former extent down the Appalachians to North Carolina.

According to Cornell University Lab of Ornithology, Golden eagle populations appear to have been stable between 1966 and 2014. Partners in Flight estimates their global breeding population to be 300,000, with 35 percent spending some part of the year in the U.S.

Golden eagles are listed as an endangered species in Maine. The decline in their numbers is directly attributed to environmental contaminants, especially DDT, that caused reproductive impairment during the post World War II era. Although these contaminants are now banned, they still persist in the birds’ bodies. Maine’s golden eagles depend heavily on wading birds as prey, which had high levels of contaminants. Five dead golden eagles have been found since 1985. Golden eagle eggs recovered from a nest in 1996 showed high levels of DDE, a variant of DDT.

Golden eagle populations have declined in the east throughout the 20th century, and were extirpated 20-40 years ago in the eastern states. Only 10 nesting territories have been documented with certainty, but at least 18 more locations are suspected. Six successful nesting attempts were recorded at three Maine eyries [nests of birds of prey] from 1955-1967. Goldens disappeared from Oxford, Franklin and Somerset counties during the 1980s. The last known nesting pair in Maine existed until 1999, then disappeared completely. That pair was heavily contaminated and had not produced young since 1986.

Today, Golden eagles can fall prey to collisions with automobiles, wind turbines, and other structures or from electrocution at power poles. Urbanization, agricultural development and changes in wildfire regimes have compromised nesting and hunting grounds.

There have been sporadic sightings of Golden eagles in recent years, and it is hoped that individual eagles from Canada may be moving into previously unoccupied eyries. Counts at hawk watch sites seem to indicate the Eastern population is slowly recovering. Golden eagles still nest in Québec and Labrador. As a result, they are spotted annually in Maine during migration season.

Adults may live 15 – 20 years in the wild, although they have been known to live 46 years in captivity. The oldest recorded Golden eagle in the wild was at least 31 years, 8 months old when it was found in Utah in 2012.

Once I was almost convinced the two friends thought they had seen golden eagles, I asked if they had misidentified immature bald eagles, which resemble each other. Both told me the birds they saw were much larger than bald eagles. My skepticism continues. Golden eagle wingspans can extend up to six feet, with a 40-inch body, and can weigh 8 – 13 pounds. Bald eagles have a body length of up to 40 inches, with wingspans of 6 – 7.5 feet, and a body weight of between 6.5 – 14 pounds. Many sources say the bald eagle has sometimes been considered the largest true raptor in North America, outsizing the Golden eagle. I summary, Bald eagles are larger than Golden eagles.

Golden eagles are uniformly brown throughout their lives. They get their name from amber or golden highlights on the head and neck. Golden eagles have shorter hawk-like bills, their lower legs are feathered to the ankles, and they soar with slightly uplifted wings, whereas a bald eagle flies with its wings stretched straight out so you can see their “fingers.” Golden eagles remain with the same mate for life. The female is larger than the male, otherwise, they look identical.

Sightseers and photographers should stay away from the nest during the nesting season, which is February through August. Like bald eagles, golden eagles are disturbed by human activities near the nests. Humans should avoid the nests during the nesting period.

Wintering areas for Maine golden eagles can stretch to the Maritime Provinces, depending on the availability of food. Their normal diet consists of ground squirrels, marmots, ptarmigan and seabirds.

I’m still not convinced they saw Golden eagles on Webber Pond.

SCORES & OUTDOORS: Browntail moth produces one generation per year; timing is important

A browntail moth nest.

Roland D. Halleeby Roland D. Hallee

The browntail moth continues to be in a lot of conversations. Now that the caterpillar is all but gone, the moth is abundant, and is the carrier of the next generation. That is why experts say they need to be dealt with now before the next round of caterpillars are hatched.

After they were sighted in all 16 Maine counties, and countless Mainers itching the blistery rash, it appears the worst may be over for the year’s browntail moth caterpillar infestation.

In April, experts predicted this summer would be the worst for browntail moth caterpillar infestations since the invasive insect arrived in Maine 100 years ago. They were right.

The browntail moth is an invasive species found only on the coast of Maine and Cape Cod. Over the last few years, it has been moving inland. This moth is an insect of both forest and human health concern.

The browntail moth caterpillar has tiny poisonous hairs that cause dermatitis similar to poison ivy on sensitive individuals. People may develop dermatitis from direct contact with the caterpillar or indirectly from contact with airborne hairs. The hairs become airborne from either being dislodged from the living or dead caterpillar or they come from cast skins with the caterpillar molts. Most people affected by the hairs develop a localized rash that will last for a few hours up to several days but on some sensitive individuals the rash can be severe and last for several weeks. The rash results from both a chemical reaction to a toxin in the hairs and a physical irritation as the barbed hairs become embedded in the skin. Resp­iratory distress from inhaling the hairs can be serious.

One of The Town Line’s supporters, while out for his daily walk, picked up this leaf from the side of the road. It is two browntail moths with the egg sacks attached. Inside each of those sacks are around 400 eggs.

Caterpillars are active from April to late June. Hairs remain toxic throughout the summer but get washed into the soil and are less of a problem over time.

Pursuant to Maine Statute Title 22, §1444, the Director of Maine CDC can declare an infestation of browntail moths (BTM) as a public health nuisance. The declaration may be made on the director’s initiative or upon petition by municipal officers.

I’ve spoken with folks who believe there will be another round of browntail moth caterpillars and their toxic hairs this fall.

Usually, when I write about certain creatures of the forest, I rarely go into great detail on the reproductive cycle, mostly because of space. But I’m making an ex­ception this week so we can see why now is the time to act on browntail moths.

The brown-tail moth produces one generation a year. It has four life stages; egg, larval, pupal, and adult. Eggs are laid in July and hatch in August. The annual cycle is approximately one month as eggs, nine months as larvae, one month as pupae, and one month as winged, sexually mature adults.

Eggs are preferentially laid on oak trees.

Pre-diapausing larvae (caterpillar): Emerge and feed gregariously starting in August after about three weeks of egg incubation.

Diapausing larvae: As a response to shortened periods of daylight, larvae build communal winter nests in the fall, inside of which they overwinter. These involve webbing, binding leaves together at tree-top branch tips. Distinct from other communal moth larvae such as eastern tent caterpillar which over-winter as eggs, then create webbed nests in branch crotches during spring and summer. Should you see a nest, cut it down and, preferably, burn it.

Post-diapausing gregarious larvae: The emerging larvae, approximately three-eighths of an inch long, resume feeding in early April synchronized with bud break, and still inhabit the winter nests as their resting places, or else make communal web-nests. These small larvae will also detach from trees and fall to the ground, then search for new trees.

Post-diapausing dispersive larvae: Once larvae reach late instars, colonies break up and larvae start feeding independently.

Pupation: Larvae pupate in June after six to eight instars.

Emergence: Imagoes (winged, sexually mature adults) appear about one month later; mate, lay eggs and die.

One of the remedies going around right now calls to fill a bucket with Dawn dishsoap (only Dawn will do) and water. Place a light near the bucket to attract the moth, which is nocturnal but attracted to light. The moths will fall in the bucket, and the soap will prevent the moth from taking flight. In the morning, dig a hole and bury the moths. Some friends have tried it and they say it works.

CICAEDA PREDICTS FIRST FROST

Well, it’s July and guess what usually happens: the cicaeda made its first appearance of the year on Saturday, July 17. We only heard it twice, but it was there. You know the old folklore, when you first hear the cicaeda’s call, the first killing frost will occur 90 days later, following the full moon, which this year, puts that date at October 20.

Isn’t it awful to be talking about frost already.

MOUNTAIN LION SIGHTING

Last week, I received another email from a reader reporting a Mountain Lion sighting. The email stated: “This week, a large cat was creeping across our property as my wife was letting out our [German] shepherd. The shepherd doesn’t chase deer but gave a hard chase of what I assumed [at first] was a bobcat. My wife said the cat was tawny [in color], had a long tail and was the same size as our shepherd (75-80 lbs.).”

It seems there have been more frequent sightings recently, but the “experts” continue to dispel their existence in Maine.

SCORES & OUTDOORS: Why are those trees dripping on me?

Roland D. Halleeby Roland D. Hallee

Have you ever noticed during the summer, especially when we head into the more humid days, that trees begin to drip on you? It isn’t sap, just water.

Well, the simple answer is the tree is “sweating.”

Now, for the more scientific explanation.

According to the United States Geological Survey, the process is actually called transpiration, and it is the process of water movement through a plant and its evaporation from aerial parts, such as from leaves but also from stems and flowers. Leaf surfaces are dotted with pores, similar to our skin, which are called stomata, and in most plants they are more numerous on the undersides of the foliage. The stomata are bordered by guard cells and their accessory cells that open and close the pore. Transpiration occurs through the stomatal apertures, and can be thought of as a necessary cost associated with the opening of the stomata to allow the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants – again similar to our sweating – changes the pressure of cells, and enables mass flow of mineral nutrients and water from roots to shoots.

Mass flow of liquid water from the roots to the leaves is driven in part by capillary action, but primarily driven by water potential differences. In taller plants and trees, the force of gravity can only be overcome by the decrease in water pressure in the upper parts of the plants due to the diffusion of water out of stomata into the atmosphere. Water is absorbed at the roots by osmosis, and any dissolved mineral nutrients travel with it through the xylem (the woody portion of the plant).

Plant transpiration is pretty much an invisible process, since the water is evaporating from the leaf surfaces, you don’t just go out and see the leaves “sweating.” Just because you can’t see the water doesn’t mean it is not being put into the air, though. During a growing season, a leaf will transpire many times more water than its own weight. An acre of corn gives off about 3,000-4,000 gallons of water each day, and a large oak tree can transpire 40,000 gallons per year.

The rate of transpiration is also influenced by the evaporative demand of the atmosphere surrounding the leaf such as humidity, change in temperature, wind and incident sunlight.

Soil water supply and soil temperature can influence stomatal opening, and thus transpiration rate. The amount of water lost by a plant also depends on its size and the amount of water absorbed at the roots. Transpiration accounts for most of the water loss by a plant, but some direct evaporation also takes place through the cuticle of the leaves and young stems. Transpiration serves to evaporatively cool plants as the escaping water vapor carries away heat energy.

Transpiration rates go up as the temperature goes up, especially during the growing season, when the air is warmer due to stronger sunlight and warmer air masses. Higher temperatures cause the plant cells which control the openings (stoma) where water is released to the atmosphere to open, whereas colder temperatures cause the openings to close.

As the relative humidity of the air surrounding the plant rises the transpiration rate falls. It is easier for water to evaporate into dryer air than into more saturated air.

Increased movement of the air around a plant will result in a higher transpiration rate. This is somewhat related to the relative humidity of the air, in that as water transpires from a leaf, the water saturates the air surrounding the leaf. If there is no wind, the air around the leaf may not move very much, raising the humidity of the air around the leaf. Wind will move the air around, with the result that the more saturated air close to the leaf is replaced by drier air.

When moisture is lacking, plants can begin premature aging, which can result in leaf loss, and transpire less water.

So, if anyone asks you why the trees are dripping, you can go into the long, scientific explanation, or you just simply say, “the tree is sweating,” and watch for the looks you will get.

SCORES & OUTDOORS: The plight of the magical lightning bug

Fireflies in a forest.

Roland D. Halleeby Roland D. Hallee

One night last week, after I did my usual bedtime reading, and my wife was playing the mind games on her tablet, I turned out the light and rolled over to get some sleep. Suddenly, my wife said, “there’s a lightning bug in here.” I looked up, and sure enough, there he was on the ceiling.

I didn’t want to crush it, because we are seeing fewer and fewer of them. So, I managed to corner it, pick it up with a piece of paper, and send it on its way, outdoors.

Now we rewind to a year ago when we were sitting by a campfire when we noticed a lightning bug. Notice I said “a,” like in one, uno, solo. It was the first lightning bug I had seen in a while. I remember when I was growing up, we used to go visit relatives in Canada, and sometimes go to a camp where we would see hundreds of lightning bugs flying around in a field. We used to capture them in a jar. You just don’t see that anymore.

Anyway, lightning bugs can make summers magical, but there is more to learn about these beauties.

First off, lightning bugs are actually fireflies. Fireflies are cute and elegant by day, but downright dazzling after darkness falls. But behind their charming facade, fireflies are fascinating little insects. Consider the following facts:

Firefly

They are beetles, not flies. Fireflies are nocturnal members of Lampyridae, a family of insects within the beetle order Coleoptera, or winged beetles. Yes, they are officially beetles.

They are alchemists, poetically speaking at least. While they don’t actually turn base metals into gold, they do create light as if by magic. When a chemical called luciferin (note the same Latin root as Lucifer) inside their abdomen/tail combines with oxygen, calcium and adenosine triphosphate, a chemical reaction occurs that creates their spectacular light.

Firefly light is incredibly efficient. The light produced by the firefly is the most efficient light ever made. Almost 100 percent of the energy in the chemical reaction is emitted as light; in comparison, an incandescent light bulb only emits 10 percent of its energy as light, the other 90 percent is lost as heat.

The main reason lightning bugs flash is to attract mates. Among most but not all species of North American lightning bugs, males fly about flashing while females perch on vegetation, usually near the ground. If the female sees a flasher and she’s ready to mate she responds by flashing right after the male’s last flash. A short flash dialogue takes place as the male flies closer and closer, and then, if all goes well, they mate.

They come in a rainbow of colors. Well maybe not the whole spectrum, but they do come in yellow, light red, green and orange.

They taste disgusting. Not that we were planning on snacking on fireflies anytime soon, but for predators that might like a light meal, beware the lightning bug. Firefly blood contains lucibufagins, which sounds like something out of a Harry Potter book but is actually a defensive steroid that tastes really awful. It is similar to that found in some poisonous toads. Predators associate the bad taste with a firefly’s light and learn not to eat bugs that glow.

However, their numbers are declining. If you’re seeing fewer fireflies each summer, you’re not alone. Evidence suggests that firefly populations may be on the decline, most likely due to a combination of light pollution, pesticide use and habitat destruction. For example, according to Smithsonian.com, if a field where fireflies live is paved over, the fireflies don’t migrate to another field, they just disappear forever.

What’s going on? Bees are on the decline; butterflies are suffering, could fireflies be facing tough times as well?

The scientific and citizen consensus is “yes.” Malaysia even holds an international symposium dedicated to conservation of the firefly. Scientists have for years been warning that the world’s estimated 2,000 species of fireflies are dwindling.

And is it any wonder? As the manmade environment continues its undying march into the natural world, where are these things supposed to live? Fireflies breed and exist in the woods and forests, along lakes and streams, in dense gardens and unruly meadows. Where are they supposed to do their firefly things when those places are paved over and built upon?

All of it doesn’t bode well.

“Fireflies are indicators of the health of the environment and are declining across the world as a result of degradation and loss of suitable habitat, pollution of river systems, increased use of pesticides in agro-ecosystems and increased light pollution in areas of human habitation,” notes the Selangor Declaration, a firefly advocating document. The decline of fireflies is a cause for concern and reflects the global trend of increasing biodiversity loss.”

Fireflies are part of our heritage; they are an iconic creature and have played a role in many, many cultures. They are the epitome of summer evenings, for many of us they served as an introduction to the wonders of nature. If we lose the fireflies, we lose an important invisible thread that connects us to the magic of the natural world. And as a species, we can’t afford to lose that right now.

SCORES & OUTDOORS: Watching the world go by on a Saturday morning

hairy woodpecker

Roland D. Halleeby Roland D. Hallee

One of the things I enjoy doing at camp on a Saturday morning is grabbing a cup of coffee and sitting on my deck, focusing on the bird feeders. There is much activity around there, not just the birds, but the squirrels and chipmunks, and the occasional cat that comes around to harass the wildlife.

On a recent Saturday, I watched two hairy woodpeckers in particular – one male, one female.

I didn’t notice at first, but after a while it became evident the male, which was perched on a suet cake, would fill its mouth, fly down to the female that was sitting on a tree stump nearby, and transferring the food to her.

What a nice thing to do, I thought. The male providing for the female – I’m not being sexist here. Actually, upon closer observation, the female would then fly off into the woods, and return a short time later. This occurred over and over, again.

My deduction at that time was the female was, in turn, returning to the nest to feed the young. Adults regurgitate and insert food in the mouths of the very young. Food is transferred from adult to older offspring through open beaks with heads at an angle.

The hairy woodpecker, Euconotopicus villosus, is a medium-sized woodpecker that is found over a large area of North America. It is approximately 9-3/4 inches in length with 15-inch wingspan. With an estimated population in 2003 of over nine million individuals, the hairy woodpecker is listed by the International Union for Conservation of Nature (IUCN) as a species of least concern.

The hairy woodpecker was described and illustrated with a hand-coloured plate by the English naturalist Mark Catesby in his The Natural History of Carolina, Florida and the Bahama Islands which was published between 1729 and 1732. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he included the downy woodpecker, coined the binomial name Picus villosus and cited Catesby’s book.

The specific epithet “villosus” is the Latin word for “hairy”. Linnaeus specified the type locality as North America, with specific mention of Raccoon, New Jersey.

Adults are mainly black on the upper parts and wings, with a white or pale back and white spotting on the wings; the throat and belly vary from white to sooty brown. There is a white bar above and one below the eye. They have a black tail with white outer feathers. Adult males have a red patch or two side-by-side patches on the back of the head; juvenile males have red or rarely orange-red on the crown.

They have a somewhat soldierly look, with their erect, straight-backed posture on tree trunks and their cleanly striped heads. Look for them at backyard suet or sunflower feeders, and listen for them whinnying from woodlots, parks, and forests.

More than 75 percent of the hairy woodpecker’s diet is made up of insects, particularly the larvae of wood-boring beetles and bark beetles, ants, and moth pupae in their cocoons. To a lesser extent they also eat bees, wasps, caterpillars, spiders, millipedes, and rarely cockroaches, crickets, and grasshoppers. A little more than 20 percent of their diet is made up of fruit and seeds. My wife usually gets suet cakes that contain fruit, seeds and nuts, thus attracting the hairy woodpeckers.

Hairy woodpeckers have helped control pest outbreaks.

The hairy woodpecker is virtually identical in plumage to the smaller downy woodpecker. The downy has a shorter bill relative to the size of its head, which is, other than size and voice, the best way to distinguish them in the field. These two species are not closely related, however, and are likely to be separated in different genera. Another way to tell the two species apart is the lack of spots on its white tail feathers (present in the downy). Their outward similarity is a spectacular example of convergent evolution. As to the reason for this convergence, only tentative hypotheses have been advanced; in any case, because of the considerable size difference, ecological competition between the two species is slight.

The hairy woodpecker inhabits mature deciduous forests in the Bahamas, Canada, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Saint Pierre and Miquelon, and the United States. It is a vagrant to Puerto Rico and the Turks and Caicos Islands. Mating pairs will excavate a hole in a tree, where they will lay, on average, four white eggs. Hairy woodpeckers are common in mature woodlands with medium to large trees.

These birds are mostly permanent residents. Birds in the extreme north may migrate further south; birds in mountainous areas may move to lower elevations.

These birds forage on trees, often turning over bark or excavating to uncover insects. They mainly eat insects, but also fruits, berries and nuts, as well as sometimes tree sap. They are a natural predator of the European corn borer, a moth that costs the U.S. agriculture industry more than $1 billion annually in crop losses and population control. They are also known to peck at wooden window frames and wood-sided homes that may house prey.

Courting birds stretch out their necks, point their bills high, and bob their heads from side to side, flicking their wings as they circle a tree trunk. They also sometimes chase each other in fast, looping flights through the trees.

The entrance to the nest is about 2 inches tall and 1.5 inches wide, leading to a cavity 8-12 inches deep. The inside widens at the bottom to make room for the eggs and the incubating bird. It’s typically bare except for a bed of wood chips at the bottom for the eggs and chicks to rest on.

The female probably selects the nesting site, but both sexes work alternately at the labor of excavating the cavity. This work requires one to three weeks, depending on how hard the wood is; a cavity in the soft wood of a poplar, which is a favorite with this species in some localities, might be excavated in a very short time. A new nest may often be recognized by the presence of fresh chips on the ground around the tree, as the birds are not very particular about removing them.

Both male and female incubate and brood the young. The male sits on the eggs and broods the young during the night and the female relieves him every morning after sunrise. They alternate these duties throughout the day. Incubation last about 11-12 days and the young leave the nest in about 28-30 days after hatching.

We continue to watch the hairy woodpeckers, and the downy, come and go at the feeders, but we haven’t seen the exchange of food recently. Maybe the fledglings are now old enough to go out on their own.

SCORES & OUTDOORS: Do moose and deer ever get their antlers caught in trees

Roland D. Halleeby Roland D. Hallee

Last week, I received an email from a colleague, and follower of this column, asking the question, “Why don’t deer and moose get their antlers caught in trees?” Well, it isn’t uncommon to find deer with their antlers caught in trees. But it usually occurs following adverse conditions, especially from flooding or being frightened into a desperate retreat.

Well, actually, that was a question I always wondered myself. I always thought that maybe their antlers were like whiskers on a cat, using them as feelers to determine whether they can pass through an opening.

It turns out I probably wasn’t far off with my assessment.

I turned to my contacts at the Maine Department of Inland Fisheries and Wildlife for an answer. According to the state moose biologist Lee Kantar, “As the moose antlers grow, the moose ‘develop’ a sense of their width.” I can only deduce that the same holds true for deer.

Following the fall rut, male deer and moose will shed their antlers. In spring or early summer, March or April, the new antlers begin to form, growing out from a pedicel bone, a bony stalk situated on the frontal bone of the skull. The antlers begin to grow at a rapid pace. During growth, they are covered with a skin, called the velvet, a living tissue, which contains many blood vessels for the nourishment of the growing bone tissue.

“During antler growth,” said Kantar, “the antlers are highly vascularized and the moose can feel where those antlers are, touching other surfaces during the growth phase.”

When the antlers have reached the size and shape characteristic for the particular species, the blood circulation in the velvet is stopped, the velvet dies, and the buck or bull then rubs off the dead skin against branches,

In the case of moose, “During antler growth this velvet layer of hair that covers the antlers are the ‘feelers’ for the antlers,” the biologist continued.

“At the end of August into September the antlers essentially harden into bone and the velvet is rubbed and sloughed off as the bull thrashes and rubs against vegetation. By this time, the bull has essentially ‘learned’ the dimensions of his new antlers for his travels.”

Deer and moose have played a very important role in the history of our country, especially deer. The American Indians and European settlers depended on deer for food clothing, implements, ornaments, ceremonial items, tools and weapons. The hides provided shelter and protection from the weather.

Did you know the term “bucks” when referring to money comes from the American Indians. Deerskins were considered valuable for clothing and the skins were called “bucks.” They were traded for various other articles.

The Netsilik Inuit people made bows and arrows using antlers, reinforced with strands of animal tendons braided to form a cable-backed bow. Several American Indian tribes also used antlers to make bows, gluing tendons to the bow instead of tying them as cables. An antler bow, made in the early 19th century, is on display at Brooklyn Museum. Its manufacture is attributed to the Yankton Sioux.

Throughout history large deer antlers from a suitable species, like the red deer, were often cut down to its shaft and its lowest tine and used as a one-pointed pickax.

Antler headdresses were worn by shamans and other spiritual figures in various cultures, and for dances. Antlers are still worn in traditional dances.

Gathering shed antlers or “sheds” attracts dedicated practitioners who refer to it colloquially as shed hunting, or bone picking. In the United States, the middle of December to the middle of February is considered shed hunting season, when deer, elk, and moose begin to shed.

In the United States in 2017 sheds fetched around $10 per pound, with larger specimens in good condition attracting higher prices. The most desirable antlers have been found soon after being shed. The value is reduced if they have been damaged by weathering or being gnawed by small animals. A matched pair from the same animal is a very desirable find but often antlers are shed separately and may be separated by several miles. Some enthusiasts for shed hunting use trained dogs to assist them. Most hunters will follow ‘game trails’ (trails where deer frequently run) to find these sheds or they will build a shed trap to collect the loose antlers in the late winter/early spring.

Lewis and Clark might never have been able to finish their journey from St. Louis to Oregon if the hunters they took with them had not furnished them with deer meat along the way. For the four months they wintered in Oregon, they had little to eat other than deer meat.

Have you ever seen a set of deformed moose antlers on a mount, and wondered why? Well, if a bull moose is castrated, either by accident or chemical means, he will quickly shed his current set of antlers and then immediately begin to grow a new set of misshapen and deformed antlers that he will wear the rest of his life without ever shedding again.

I know I wandered off the initial subject, but I found all this information fascinating. I hope you did, too.

SCORES & OUTDOORS: Why are they called June bugs when they generally appear in May

Green June beetle (left), June Bug (right)

Roland D. Halleeby Roland D. Hallee

Well, the first June bug of the year made its appearance at camp on Saturday, May 29, at 10:30 p.m. We were, after all, still in May. To date, however, I have only seen three. I remember one summer, around 2002, we were literally swarmed one night while sitting around a camp fire. We left outside lights on, and in the morning, I counted 53 dead June bugs on our deck. We have not seen nearly that many since.

Generally, June bugs, Phyllophaga, do make their appearance in mid- to late-May. So why are they called June bugs? It all depends on what you want to call them. They are also known as May beetles and June beetles. But, the name is derived from the fact that adult June bugs emerge from the soil at the end of spring or the beginning of summer.

Females bury their eggs just below the soil surface in the fall, they pupate and emerge in the spring. They hatch within three to four weeks and feed on grass and plant roots from several months to as long as three years. In spring, these grubs, as they are called, grow into pupae. Within three weeks, these mature into adult June bugs.

Grubs, when full grown, live in the soil and feed on plant roots, especially those of grasses and cereals, and are occasional pests in pastures, nurseries, gardens and golf courses. An obvious indication of infestation is the presence of birds, especially crows, peeling back the grass to get to the grubs. A way to test for the presence of these beetles is drenching an area of lawn with water, that will cause larvae to emerge at the surface.

Some small mammals, including skunks and moles, feed on the grubs.

The grubs have been known to attack vegetables and other garden plants, such as lettuce, raspberries, strawberries, potatoes and young ornamental trees. Maintaining a healthy lawn is a good step in deterring the grubs from establishing themselves.

Injury to the roots and rootstock causes small saplings and tender tap-rooted plants like lettuce to wilt suddenly or to show stunted growth and a tendency to shed leaves prematurely. Plants growing in rows are usually attacked in succession as the grubs move along from one plant to the next. Chafer grubs feed below ground for three – four years before changing into adult beetles.

June bugs are harmless. They do not bite, sting or spread disease. However, I did see one of my friends move faster than I have ever seen her move before, while sitting around a camp fire last weekend, when one landed on her. To be honest, it’s the natural reaction by most people, including yours truly.

Again, they are harmless, but because they are attracted to light they can make an evening sitting on your porch or deck a little unpleasant. Even if there is no light outdoors, they can be attracted to lights inside your home. I know at camp, when we’re spending time indoors after dark, they come “knocking” on our windows. The sound of June bugs buzzing and bumping against window screens in early summer is a very common occurrence over many parts of the U.S. Adult June bugs are extremely clumsy, especially in the air.

Scientists are still undecided on the precise explanation for this behavior. Several thoughts have been advanced, but no single theory has come about that can account for why so many different nocturnal insect species gravitate to sources of light. June bugs usually are a half-inch to an inch and a quarter in length. They can fly and you will find them swarming around street lights at night.

Now, let’s do some “did you know.”

  • Exposure to light for longer intervals will kill June bugs. That is why you will find them dead in the morning under porch lights and windows.
  • Don’t leave a window open during May-June period. They will enter your house and die, leaving you with a mess to clean up. If they do enter, remember, they don’t bite and are harmless, just annoying.
  • There are over 200 different species of June bugs in the United States.
  • A natural enemy of the June bug is the pyrgota fly larva, which feeds on the beetles, eventually killing them.
  • The June bug larvae, called white grubs, are considered excellent fish bait, and are staples in the diets of native people in South America, Australia, and Asia.
  • Have a pet lizard or toad? The beetles make excellent, tasty food for them.

There is another popular June beetle that’s active during the day. It is the Green June Beetle, and are found in our region of the Northeast, extending from Maine to Georgia and as far west as Kansas. These are not very good for the garden either. The head, legs and under-body is shiny green, while its wings are dull metallic green, with slight gold contrast to its sides.

Numerous songs have been written about June bugs, to include: “Junebug”, by The B-52s; “Junebug”, from the album Good Morning Spider by Sparklehorse; “Junebug”, by Robert Francis; “June Bug”, by Melvins; “Junebug”, by Stan Van Samang; and “Junebug”, by Kate Ryan.

So day and night, during early summer, these beetles can be destructive to vegetation, and just plain annoying to humans.
