SCORES & OUTDOORS: Cicada’s songs fill the air

a cicada

Roland D. Halleeby Roland D. Hallee

Last week, while doing some yard work, my wife noticed some insects on our outdoor fire pit. When summoned, I went over and identified the “bug” as the cicada exoskeleton, the part the cicada leaves behind its external skeleton, a hard, protective outer shell. We counted 11 of them. As a cicada grows, it outgrows its exoskeleton and must molt, shedding the old, hard shell and emerging as a larger, soft-bodied form.

The cicadas are a superfamily of insects, with more than 3,000 species described from around the world. Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings. They have an exceptionally loud song, produced in most species by the rapid buckling and unbuckling of drum-like tymbals. They typically live in trees, feeding on watery sap from xylem tissue, and laying their eggs in a slit in the bark. Most cicadas are cryptic. The vast majority of species are active during the day as adults, with some calling at dawn or dusk. Only a rare few species are known to be nocturnal.

One exclusively North American genus, (the periodical cicadas), which spend most of their lives as underground nymphs, emerge in predictable intervals of 13 or 17 years, depending on the species and the location. The unusual duration and synchronization of their emergence may reduce the number of cicadas lost to predation, both by making them a less reliably available prey (so any predator that evolved to depend on cicadas for sustenance might starve waiting for their emergence), and by emerging in such huge numbers they will satiate any remaining predators before losing enough of their number to threaten their survival as a species.

The annual cicadas are species that emerge every year. Though these cicadas’ life cycles can vary from one to nine or more years as underground nymphs, their emergence above ground as adults is not synchronized, so some members of each species appear every year.

The “singing” of male cicadas is produced principally and in the majority of species using a special structure called a tymbal, a pair of which lies below each side of the anterior abdominal region. The structure is buckled by muscular action and, being made of resilin, unbuckles rapidly on muscle relaxation, producing their characteristic sounds. Some cicadas, however, have mechanisms for stridulation, sometimes in addition to the tymbals. Here, the wings are rubbed over a series of midthoracic ridges. Although only males produce the cicadas’ distinctive sounds, both sexes have membranous structures called tympana (singular – tympanum) by which they detect sounds, the equivalent of having ears.

cicada exoskeleton

For the human ear, telling precisely where a cicada song originates is often difficult. The pitch is nearly constant, the sound is continuous to the human ear, and cicadas sing in scattered groups. In addition to the mating song, many species have a distinct distress call, usually a broken and erratic sound emitted by the insect when seized or panicked. Some species also have courtship songs, generally quieter, and produced after a female has been drawn to the calling song. Males also produce encounter calls, whether in courtship or to maintain personal space within choruses.

Most cicadas go through a life cycle that lasts two – five years. Some species have much longer life cycles, such as the North American genus, which has a number of distinct “broods” that go through either a 17-year or in some parts of the region, a 13-year life cycle. For example, a 17-year cicada with a predator with a five-year life cycle will only be threatened by a peak predator population every 85 (5 × 17) years, while a non-prime cycle such as 15 would be endangered at every year of emergence. Cicadas are commonly eaten by birds and mammals, as well as bats, wasps, mantises, spiders, and robber flies. In times of mass emergence of cicadas, various amphibians, fish, reptiles, mammals, and birds change their foraging habits so as to benefit from the glut. Newly-hatched nymphs may be eaten by ants, and nymphs living underground are preyed on by burrowing mammals such as moles.but observations of predator responses refute the claim.

In mythology and folklore Cicadas have been used as money, in folk medicine, to forecast the weather, to provide song (in China), and in folklore and myths around the world.

Cicadas feed on sap; they do not bite or sting in a true sense, but may occasionally mistake a person’s arm for a plant limb and attempt to feed. Male cicadas produce very loud calls that can damage human hearing.

Cicadas are not major agricultural pests, but in some outbreak years, trees may be overwhelmed by the sheer numbers of females laying their eggs in the shoots. Small trees may wilt and larger trees may lose small branches. Although in general, the feeding activities of the nymphs do little damage, during the year before an outbreak of periodic cicadas, the large nymphs feed heavily and plant growth may suffer.[111] Some species have turned from wild grasses to sugarcane, which affects the crop adversely, and in a few isolated cases, females have oviposited on cash crops such as date palms, grape vines, citrus trees, asparagus, and cotton. Cicadas sometimes cause damage to ornamental shrubs and trees, mainly in the form of scarring left on tree branches where the females have laid their eggs. Branches of young trees may die as a result.

Now we know a little more about the insect that makes that loud, buzzing noise in mid-summer.

SCORES & OUTDOORS: Here comes another Asian nemesis

Asian longhorned tick

Roland D. Halleeby Roland D. Hallee

The University of Maine and the Maine Department of Agriculture, Conservation and Forestry (DACF) have confirmed the presence of an invasive Asian longhorned tick in the state for the first time.

The tick was submitted through University of Maine Cooperative Extension’s passive tick surveillance program and identified by staff at the UMaine Extension Tick Lab. Follow-up active surveillance in the surrounding area did not detect any additional specimens.

The specimen, a nymph, was collected in Cumberland County and submitted for identification and pathogen testing. This marks the first known occurrence of the species in Maine and raises important considerations for livestock care, wildlife management and public health.

“This discovery underscores the critical importance of continued tick surveillance in Maine,” said Griffin Dill, director of the UMaine Extension Tick Lab. “While this appears to be an isolated case, we are closely monitoring the situation and coordinating with state and federal partners. Early detection is essential to understanding and mitigating the potential risks associated with this species.”

Why the Asian Longhorned Tick Is a Growing Concern.

Native to East Asia, the Asian longhorned tick was first confirmed in the United States in New Jersey in 2017 and has since spread through more than twenty states. Unlike most ticks, female Asian longhorned ticks can reproduce without mating, creating infestations from a single individual and posing a unique challenge for control. The tick found in Maine was at a juvenile stage that can’t reproduce.

They feed on a wide range of hosts, including livestock, pets, wildlife and people. In other regions, they have been shown to transmit the cattle pathogen Theileria orientalis, which can cause significant illness. Research is ongoing to understand if this tick species can spread the pathogens found in Maine and elsewhere in the U.S.

In response to the recent finding, state and research partners are intensifying monitoring efforts to determine whether the Asian longhorned tick is persistent in Maine and, if so, to understand its potential spread. UMaine, DACF and the MaineHealth Institute for Research will continue targeted active surveillance in the region and encourage the public to remain vigilant.

How Maine Can Prepare

DACF, in collaboration with the UMaine Extension Tick Lab and Maine CDC, recommends these preventative measures:

Use tick preventatives: Veterinarians should advise on effective treatments for livestock and pets.

Conduct rigorous tick checks: Examine animals, especially ears, eyes, tails, and feet, regularly and remove any ticks found promptly and safely.

Maintain the landscape: Keep yards and pastures brush-free and create mulch or gravel borders to reduce tick habitat.

Continued Monitoring and Reporting

The presence of Asian longhorned ticks in Maine and neighboring states, along with the data from UMaine Extension’s ongoing passive surveillance program, highlights the urgency of staying alert.

“If you find an unusual-looking tick or suspect an infestation, don’t hesitate to report it to DACF,” said Dr. Rachael Fiske, assistant state veterinarian. “In this and every instance, early detection is key to protecting Maine’s livestock, pets, wildlife and public health.”

To report findings or for more information, contact the Maine DACF’s Animal Health Division, 207.287.3701; animalhealth.dacf@maine.gov.

SCORES & OUTDOORS: Hummingbirds vs. bees; why the hummers want no part of them

Roland D. Halleeby Roland D. Hallee

My wife has a strong liking for hummingbirds. At camp, she has five feeders spread around the lot. We watch them constantly.

Lately – I’ve counted at least eight – they have been swarming the feeders, fighting amongs themselves, and it’s a wonder they get to eat at all, what with chasing any other hummer that approaches a feeding station.

Add to that the presents of bees, who during this dry spell, have been in search of liquids themselves.

Those tiny bees, keep chasing off the hummingbirds. Why would a diminutive bee scare away a hummingbird, which even though tiny themselves, are behemoths compared to the bees?

Hummingbirds belong to an avian family and their closest relatives are the equally fascinating swifts. Hummingbirds are small with long, narrow bills and small, saber-like wings.

Males (and occasionally females) often have a colorful gorget – small, stiff, highly reflective, colored feathers on the throat and upper chest. These shiny feathers and others around the head may look sooty black until a hummingbird turns its head to catch the sun and display the intense, metallic spectral color.

It makes sense that the smallest birds come from the smallest eggs, but how small? The one to two eggs in a ruby-throated hummingbird clutch are about as tiny as peas and are placed in a walnut shell-sized cup woven from spider webs and plant material.

Hummingbirds and swifts are able to stroke with power both on the down- and up-beat of a wing flap. Their power and small size allow tremendous agility in flight. In fact, hummingbirds are the only vertebrates capable of sustained hovering (staying in one place during flight), and they can fly backward and upside-down as well.

To their maneuverability, hummingbirds add speed and stamina. They have been clocked at close to 30 mph indirect flight and more than 45 mph during courtship dives. Migratory ruby-throated hummingbirds have no problem flying 18 to 20 straight hours to cross the Gulf of Mexico, powered by their fat stores and given a bit of help from winds.

A ruby-throated hummingbird’s heart beats from 225 times per minute when the bird is at rest to more than 1,200 times per minute when it is flying. Its wings beat about 70 times per second in direct flight and more than 200 times per second while diving.

Hummingbirds are one of the few groups of birds that are known to go into torpor. Torpor is a very deep, sleep-like state in which metabolic functions are slowed to a minimum and a very low body temperature is maintained. If torpor lasted for long periods, we would call it hibernation, but hummingbirds can go into torpor any night of the year when temperature and food conditions demand it.

Their high-energy lifestyle compels hummingbirds to locate reliable food resources. Feeding on flowers puts hummingbirds at the mercy of the flowering seasons of the plants upon which they depend. Hummingbirds solve this by being very mobile, and their movements are often shaped by the changing pattern of flower production over time.

Hummingbirds don’t always depend entirely on flowers. During the breeding season, in particular, hummingbirds hover mid-air and catch small flying insects to eat and feed to their nestlings.

In northern and high-elevation areas, hummingbirds depend upon sap-wells of woodpeckers known as sapsuckers. The woodpeckers are able to keep the sugary sap of trees flowing, and the hummingbirds sneak in to take advantage of the woodpeckers’ work.

Hummingbirds are, for the most part, unsociable. In fact, the adjectives pugnacious and feisty are often appropriate. When more than one hummingbird is around, it is often a scene of repeated high-speed chases. In fact, male and female hummingbirds do not form a pair-bond after mating, and the female is left to care for eggs and chicks alone.

What is all this fighting about? Plants take time to secrete nectar into their flowers. In an ideal world, hummingbirds should time their visits to flowers to take advantage of a full load of nectar. But they wait to feed at a flower at the risk of other hummingbirds beating them to the punch. It is therefore worth the effort for hummingbirds to chase away competitors, so they have access and control of their favorite flowers.

So, let’s get back to the original question.

Those tiny bees are able to scare away a hummingbird because a bee sting to a hummingbird can be fatal. Hummingbirds have very small bodies and a single bee sting, especially in a sensitive area, can be enough to cause death due to the venom. While hummingbirds can sometimes be aggressive towards bees, the bees can also be aggressive towards them, especially around feeders.

With only about a month left before hummingbirds head south, enjoy the time spent watching their antics.

Another note: we’ve had bird feeding stations for years, and attract many different, common songbirds. Recently, hummingbirds have been buzzing around like an airport with no flight controllers. Can they be scaring off other birds? We haven’t seen our songbirds in weeks.

We’re wondering if they could be bullying the other birds away? It seems that since they’ve taken over, our regular visitors have stopped appearing.

The answer: Yes, hummingbirds can sometimes scare away other songbirds from feeders, primarily due to their territorial and aggressive nature, especially around nectar sources. While they are small, hummingbirds can be quite assertive in defending their feeding territories, which can deter larger or more timid birds from approaching.

SCORES & OUTDOORS: That would be a great golden digger wasp

great golden digger wasp

Roland D. Halleeby Roland D. Hallee

A friend of mine was asked by an acquaintance if she recognized a certain bug they found hanging around the garden, and boring holes in the yard. She suggested the person send the photo to me for identification. With the help of my insider at the Maine Department of Inland Fisheries and Wildlife, we came up with this.

The insect is a Great Golden Digger Wasp. Despite its vivid, alarming coloration, the Great Golden Digger Wasp is not an aggressive species of the wasp.

The Great Golden Digger Wasp appears every June, and remains for the next couple of months, going through a methodical routine.

Unfortunately, social wasps life the yellow jackets and hornets give all wasps a bad name. Solitary wasps like the Great Golden Digger Wasp are virtually harmless. They do not guard their nests and are not aggressive towards humans. Females are equipped with stingers but use them only on their prey, although a rare sting to a human may occur if the wasp is grabbed or stepped on. Male wasps may act aggressively, but they have no stingers and can do no harm.

Unlike the social wasps, which live commune-style with a queen and non-reproducing minions that handle the hard labor, digger wasps are solitary creatures.

The Great Golden Digger Wasp measures more than an inch in length. They have a black head, orange and black body, orange legs, and iridescent amber wings. Short, golden hairs cover its head and thorax.

The first reaction of a gardener who confronts a large, intimidating-looking Great Golden Digger Wasp may be to grab a can of bug spray. Don’t do it! Not only are these bugs harmless to humans, they provide many benefits to the garden.

Adult wasps, both male and female, pollinate plants by feeding on flower nectar. Female wasps prey on grasshoppers and similar pests that otherwise cause a lot of damage to vegetable and ornamental plants in the garden. And by digging holes in the ground, the wasps help to aerate the soil and improve drainage.

The female wasp will spend her short life engaged in the methodical building and stocking of a half dozen or so nests.

When the wasp hunts, she stings her prey and releases paralyzing venom. She transports the paralyzed insect back to her nest by air – if it is light enough to fly with – or by dragging it across the ground by its antennas. On the way, she may have to fend off robins, sparrows, and other birds intent on stealing the insect from her. They only hunt members of the grasshopper family. They are great pollinators and should be welcome in your garden.

The female digs a chambered tunnel in open ground, and proceeds to stock it with food for her young to eat. She searches for insects, which usually includes crickets, katydids and grasshoppers. Then she goes through a ritual that is unique among insects. The prey is placed at the opening of the tunnel while she crawls inside to inspect it. Then, she comes back out and graps the unlucky insect by the antennae and pulls it inside head-first. She has been genetically patterned to perform these motions, and if anything changes, she cannot complete this task.

If the prey insect is moved a few inches from where she left it, she will quickly locate it and pull it to the entrance. Once again she will go inside to inspect the burrow. This scene can be repeated time and time again, and she will perform the same acts. What looks like a thoughtful precaution, is simply genetically programmed into the species.

Should one of the antennae break off, she will usually leave her catch and go find another insect. She is not able to figure out that by grabbing it by a leg, she can accomplish the same thing. It’s either by the antennae or its move on to another prey.

Upon returning to the nest, the wasp drops her prey outside the entrance while she reopens and inspects the tunnel. She then drags her still-paralyzed victim to a nesting chamber, and lays one egg on top of it.

When she leaves the nest, she closes up the nesting chamber behind her. She will not return. Over the fall and winter, the wasp larva will undergo a complete metamorphosis. It will emerge in June as an adult and begin the process all over again. When the adult emerges from the underground nest where it hatched the previous summer, it has but one job to do: to reproduce.

Great Golden Digger Wasps can be found in North America, Mexico, Central and South America, and even the Caribbean.

So, if you’re lucky enough to encounter a Great Golden Digger Wasp in your garden, leave her alone. She’s working hard. Just step back and observe one of the most unique inhabitants in the garden.

SCORES & OUTDOORS – Black crappie: fun to catch, tasty to eat

Black crappie

Roland D. Halleeby Roland D. Hallee

Because I spend my summers at Webber Pond, in Vassalboro, I have the chance to fish that lake extensively. In the 38 years my wife and I have summered there, we have caught plenty of fish of many various species: small and largemouth bass, white perch, yellow perch, chain pickerel, eels, to name a few.

Until 2009, we had not heard of anyone catching black crappie. But the catch has become quite common in the ensuing years.

The first question that comes to mind is whether the fish ladder at the dam on the Webber Pond Road (built in 2008) had anything to do with it. Probably not, but why, all of a sudden, are there crappies in the lake? That is the same question people residing at Togus Pond, in Augusta, have been asking, since the fish has made its appearance there also.

Black crappie, also known as calico bass, is a member of the sunfish family. These fish seem to fall in the love-hate category. Many people I have spoken with like the fish, saying they are a very tasty pan fish, while others put them in the same class as sunfish – what they describe as trash fish.

Despite that, they are a fairly popular fish although most of them have been artificially introduced. Black crappies are a schooling fish which leads to fast, intense fishing, an experience that many anglers prefer.

Adult crappies are typically around 6 – 12 inches long and weigh somewhere between two to three pounds. Typical crappie fisheries produce fish between 6 and 11 inches long, although crappies exceeding 14 inches and three pounds have been caught in Maine waters.

Their spawning season varies by location, due to the species’ great range. Water temperature at breeding is 58 – 68 degrees F. and occurs between April and June. Spawning takes place in a nest built by the male, who guards the eggs and young.

Closely resembling bass and sunfish species, which have 10 – 12 dorsal fin spines, crappies possess 6 – 8 dorsal fin spines. Body form is very deep and narrow, much like the sunfish. The coloration is silvery-olive to golden brown, with an irregular mosaic of dark black blotches.

Adults feed predominantly on smaller species, including the young of their own predators. They have diverse diets, however, including zooplankton, insects and crustaceans. This could be an added plus to Webber Pond. Over time, Webber Pond had experienced a tremendous improvement in water quality due, in part, to the return of the alewives, who also feed on zooplanktin. Zooplanktin feed on algae, and when alewives, in turn, ingest the zooplanktin and leave the waters in the fall, they take with them large quantities of algae. With the addition of the black crappie as an eater of zooplanktin, it can be interpreted as a potential for even more improvements.

By day, crappies tend to be less active and to concentrate around weed beds or submerged objects, such as logs and boulders. They feed especially at dawn and dusk, moving then into open water or approaching the shore. Because of their diverse diets, crappie may be caught in many ways, including casting light jigs, trolling with minnows or artificial lures, using small spinnerbaits or worm and bobbers. We catch them on red shad plastic worms, using the cast and retrieve method.

When we catch a few, we have kept our catch and fileted them. Rolling them in a batter of egg and corn meal, with some garlic pepper, we fry them in a pan, or cook them over an open fire. They make great fish filet sandwiches with cheese and lettuce.

Fishing for black crappies is most productive during the early morning or early evening while the air is relatively cool. They can be caught during the day, however, in more active waters. Be patient.

Black crappie are fairly common in the waters of southern Maine and in some of the Belgrade lakes.

SCORES & OUTDOORS: Pesticides take toll on bees

Honey Bee

Roland D. Halleeby Roland D. Hallee

Recently I read an article about the state of bumble bees and honey bees. It seems a common class of pesticide, neonicotinoids, is causing problems for honeybees and bumblebees, by attacking the central nervous system, causing a reduction in weight and number of queens in bumblebee hives. It also causes them to become disoriented, and fail to return to their hives.

Bumble Bee

Neonicotinoids are a class of neuro-active insecticides chemically similar to nicotine. As of 2013 neonicotinoids have been used in the U.S. on about 95 percent of corn and canola crops, the majority of cotton, sorghum, and sugar beets and about half of all soybeans. They have been used on the vast majority of fruit and vegetables, including apples, cherries, peaches, oranges, berries, leafy greens, tomatoes, and potatoes, to cereal grains, rice, nuts, and wine grapes. Imidacloprid is possibly the most widely used insecticide, both within the neonicotinoids and in the worldwide market.

For more than a decade, pollinators of all types have been in decline, mostly because of loss of habitat, inadequate food sources, diseases caused by parasites and viruses, and bee management practices, along with perhaps some pesticides.

In a British study, researchers doused bees with the pesticide and moved their hives out to a field. After six weeks, they found the pesticide-treated hives to be 10 percent lighter than those that weren’t treated; and more important, the hives that had pesticides lost about 85 percent of their queens.

Even though lower doses were used with bumblebees, it seems that bumblebees are more sensitive to the pesticide and that issue is worthy of more study.

Honeybees, which aren’t native to America, are managed by professional beekeepers, carted from farm to orchard, and raised to produce honey. Bumblebees, native to this country, are wild pollinators.

Bumblebees are typically found in higher latitudes and high altitudes, through exception exist. They are also found in cold climates where other bees might not be found because bumblebees can regulate their body temperature.

Bumblebees are social insects that feed on nectar and gather pollen to feed their young. Bees are also needed to pollinate fruit, vegetables and nuts. Without them, experts say our diets would be very bland.

Bumblebees generally visit flowers exhibiting the bee pollination syndrome. They tend to visit the same patches of flowers every day, as long as they continue to find nectar and pollen. Pollen is removed from flowers deliberately or incidentally by bumblebees. Once a bumblebee has visited a flower, it leaves a scent mark on the flower. This scent mark deters visitation of the flowers by other bumblebees until the scent degrades.

Once they have collected nectar and pollen, bumblebees return to the nest and deposit the harvested nectar and pollen into brood cells, or into wax cells for storage. Unlike honey bees, bumblebees only store a few days’ worth of food, and so they are much more vulnerable to food shortages.

Queen and worker bumblebees can sting. The bumblebee stinger has no barbs and is capable of multiple stings. They are not normally aggressive, but will sting in defense of their nest or if harmed. They will attack host colony members, but usually ignore other animals and humans unless disturbed.

Multiple species of bees are either seeing a decline or disappearing entirely from the European landscape, along with some native to America, some of them may even be extinct.

According to 20th century folklore, the laws of aerodynamics prove that bumblebees should be incapable of flight, as it doesn’t have the capacity to achieve flight with the degree of wing loading necessary. In 1934, French entomologist Antoine Magnan included the following passage in the introduction to his book, Le Vols des Insectes: “First prompted by what is done in aviation, I applied the laws of air resistance to insects, and I arrived … at this conclusion that their flight is impossible.” Apparently, the bumblebee’s wing function is that the wings work similarly to helicopter blades. Bees beat their wings approximately 200 times a second. Their thorax muscles do not expand and contract on each nerve firing but rather vibrate like a plucked rubber band.

So, environmental activists and some beekeepers are convinced the pesticide is a problem. Entomologists have said without bees, “we’d be a scurvy-ridden society.”

SCORES & OUTDOORS: Are fireflies making a comeback? Seeing more this year than past summers

Fireflies in action.

Roland D. Halleeby Roland D. Hallee

A little while back someone inquired about fireflies and how they have been scarce as of late. Well, the other night, my wife and I were treated with a light show like we have not seen in a while. We were sitting enjoying the warm summer night when the area to our right became lighted up with dozens of them.

Fireflies are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly during twilight, to attract mates. Light production is thought to have originated as a warning signal the larvae were distasteful. This ability to create light was then co-opted as a mating signal and, in a further development, adult female fireflies mimic the flash pattern of the Photinus beetle to trap their males as prey.

Fireflies are found in temperate and tropical climates. Many live in marshes or in wet, wooded areas where their larvae have abundant sources of food. Although all known fireflies glow as larvae, only some species produce light in their adult stage, and the location of the light organ varies among species and between sexes of the same species. Fireflies have attracted human attention since classical antiquity; their presence has been taken to signify a wide variety of conditions in different cultures and is especially appreciated aesthetically in Japan, where parks are set aside for this specific purpose.

Firefly

Fireflies are beetles and in many aspects resemble other beetles at all stages of their life cycle, undergoing complete metamorphosis. A few days after mating, a female lays her fertilized eggs on or just below the surface of the ground. The eggs hatch three to four weeks later.

The larvae feed until the end of the summer. Most fireflies hibernate as larvae. Some do this by burrowing underground, while others find places on or under the bark of trees. They emerge in the spring. The larvae of most species are specialized predators and feed on other larvae, terrestrial snails, and slugs. Some are so specialized they have grooved mandibles that deliver digestive fluids directly to their prey. The larval stage lasts from several weeks up to, in certain species, two or more years. The larvae pupate for one to two-and-a-half weeks and emerge as adults.

Light production in fireflies is due to the chemical process of bioluminescence. This occurs in specialized light-emitting organs, usually on a female firefly’s lower abdomen. Adults emit light primarily for mate selection.

Many fireflies do not produce light. Usually these species are diurnal, or day-flying. A few diurnal fireflies that inhabit primarily shadowy places, such as beneath tall plants or trees, are luminescent.

Like Fourth-of-July fireworks, cool swims on hot days, and lazy vacations, fireflies are a sign of summer. Many of us have cherished memories of spotting and catching them during warm summer evenings and running through fields that sparkled as if strewn with stars. But there are signs our
kids may not grow up with the same firefly memories we had. That’s because fireflies are disappearing from marshes, fields and forests all over the country – and all over the world. And if it continues, fireflies may fade forever, leaving our summer nights a little darker and less magical.

Why Are Fireflies Disappearing? Nobody knows for sure. But most researchers blame two main factors: development and light pollution.

Most species of fireflies thrive as larvae in rotting wood and forest litter at the margins of ponds and streams. And as they grow, they more or less stay where they were born. Some species are more aquatic than others, and a few are found in more arid areas—but most are found in fields, forests and marshes. Their environment of choice is warm, humid and near standing water of some kind—ponds, streams and rivers, or even shallow depressions that retain water longer than the surrounding ground.

The problem is that in America and throughout the world, our open fields and forests are being paved over, and our waterways are seeing more development and noisy boat traffic. As their habitat disappears under housing and commercial developments, firefly numbers dwindle. Logging, pollution and increased use of pesticides may also contribute to destroying firefly habitat and natural prey.

The next time you see a firefly, thank it for the memories, and hopefully the next generation will also be able to enjoy them.

Regarding Scores & Outdoors column on Japanese Beetles in the July 10, 2025, issue of The Town Line.

Thank you for writing about Japanese beetles and warning folks not to use traps. Just this morning I was knocking them into a #10 can of water topped with a few drops of dish detergent. It keeps them from flying out of the can, then I strain then out for our ducks as a special treat. I discovered that the small Viriginia creeper vine on the north fence of our vegetable garden is attracting them away from the asparagus bed and other plants making them easier to catch. I now have what the Integrated Pest Management folks call trap cropping. I casually planted some zinnias in my community garden bed which is having the same effect – my flowers aren’t pretty, but the Japanese beetles are feasting there instead of the other’s folk’s plants.

SCORES & OUTDOORS: Is it a bad year for Japanese beetles?

Japanese beetle

Roland D. Halleeby Roland D. Hallee

A reader recently asked about the Japanese beetle, and the lack of them so far this year. She said they usually devour her roses, but has not seen one this year.

So far, It’s difficult to say definitively if it will be a bad year for Japanese beetles, but there are indications that it could be, particularly in certain regions. Cooler spring weather has delayed their emergence, and fluctuating weather patterns may have impacted their populations. However, their numbers can vary greatly by location, and it’s still early in the season to assess the full extent of the impact.

The Japanese beetle is a species of scarab beetle. Due to the presence of natural predators, the Japanese beetle is not considered a pest in its native Japan, but in North America and some regions of Europe, it is a noted pest to roughly 300 species of plants. Some of these plants include rose bushes, grapes, hops, canna, crape myrtles, birch trees, linden trees, and others.

The adult beetles damage plants by “skeletonizing” the foliage (i.e., consuming only the material between a leaf’s veins) as well as, at times, feeding on a plant’s fruit. The subterranean larvae feed on the roots of grasses.

The beetle is native to Japan, but is an invasive species in North America and Europe.

While the larvae of Japanese beetles feed on the roots of many genera of grasses, the adults consume the leaves of a much wider range of hosts, including these common crops: beans, cannabis, strawberry, tomato, pepper, grape, hop, rose, cherry, plum, pear, peach, raspberry, blackberry, corn, pea, okra, and blueberry.

Japanese beetles are primarily attracted to the scent of certain flowers, fruits, and plants, as well as the pheromones released by other Japanese beetles. They are especially drawn to bright and vibrant colors like white, yellow, and pink, and they prefer plants with soft, tender leaves, especially roses, grapes, and fruit trees.

The first written evidence of the insect appearing within the United States was in 1916 in a nursery near Riverton, New Jersey The beetle larvae are thought to have entered the United States in a shipment of iris bulbs prior to 1912, when inspections of commodities entering the country began. As of 2015, just nine western states of the United States were considered free of Japanese beetles. These beetles have been detected in airports on the west coast of the United States since the 1940s. Only three were found in Washington State in 2020, but from late June to September 3, 2021, there were over 20,000 found in Grandview alone.

The first Japanese beetle found in Canada was inadvertently brought by tourists to Yarmouth, Nova Scotia, by ferry from Maine in 1939. During the same year, three additional adults were captured at Yarmouth and three at Lacolle in southern Québec.

Eggs are laid individually or in small clusters near the soil surface. Within approximately two weeks, the ova hatch, then the larvae feed on fine roots and other organic material. As the larvae mature, they become c-shaped grubs, which consume progressively coarser roots and may do economic damage to pasture and turf at this time.

Larvae hibernate in small cells in the soil, emerging in the spring when soil temperatures rise again. Within four to six weeks of breaking hibernation, the larvae will pupate. Most of the beetle’s life is spent as a larva, with only 30 – 45 days spent as an imago. Adults feed on leaf material above ground, using pheromones to attract other beetles and overwhelm plants, skeletonizing leaves from the top of the plant downward. The aggregation of beetles will alternate daily between mating, feeding, and ovipositing. An adult female may lay as many as 40 – 60 ova in her lifetime.

Throughout the majority of the Japanese beetle’s range, its life cycle takes one full year.

Owing to their destructive nature, traps have been invented specifically to target Japanese beetles. These comprise a pair of crossed walls with a bag or plastic container underneath and are baited with floral scent, pheromone, or both. However, studies conducted at the University of Kentucky and Eastern Illinois University suggest beetles attracted to traps frequently do not end up in the traps; instead, they land on plants in the vicinity and cause more damage along the flight path and near the trap than may have occurred if the trap were not present.

I have battled with Japanese beetles in my garden before, but now that she mentioned it, I haven’t seen one in quite a while. I thought I had conquered them.

SCORES & OUTDOORS: Many questions about poison ivy

poison ivy leaves

Roland D. Halleeby Roland D. Hallee

For some reason, this year, I am getting more and more questions about poison ivy. Where is it? What does it look like? What do you do about it and how do you treat it?

All very legitimate questions.

As we all know, poison ivy and other members of its family can cause a lot of misery to humans should they make contact with the toxic plant.

Poison ivy, Toxicodendron radicans, is a member of the cashew family. It usually grows as a vine twining on tree trunks or crawls along the ground. It is generally found in all states in the United States east of the Rocky Mountains and southern Canada, specifically Québec, Ontario and Manitoba.

It may grow as a forest understory plant, although it is only somewhat shade tolerant. The plant is extremely common in suburban areas of New England. It can grow in many types of soil, and is not sensitive to soil moisture, although it does not grow in arid conditions.

The leaves of the poison ivy are red in the spring, turning to a shiny green later. Come fall, they turn yellow, red or orange. Each leaf is made up of three leaflets more or less notched at the edges. However, don’t let that be the determining factor. Some leaves have smooth edges. Two of the leaves appear opposite each other on the stem while the third one stands alone at the tip. Later in the season, clusters of poisonous, whitish, waxy looking berries will form.

Many people have difficulty identifying the plants because it can look like other plants, while, sometimes, other plants are mistaken as poison ivy.

Obviously, contact with the plant should be avoided. You can become infected simply by walking through the bush, taking off your shoes, and making contact with your skin.

poison ivy leaves

Poison ivy in the U.S. is more common now than when Europeans first arrived in North America. The development of real estate adjacent to wild, undeveloped land caused the plant to spread into vast, lush colonies in these areas. Also, birds will eat the berries and transplant them on new areas along with their droppings. It’s also spread by other animals as the seeds remain viable after passing through the digestive system.

A study by researchers at the University of Georgia found that poison ivy is particularly sensitive to carbon dioxide levels, increasing in numbers due to a higher concentration in the atmosphere. Poison ivy’s growth has doubled since the 1960s, and could possibly double again as the carbon dioxide levels continue to rise.

What do you do once you’ve made contact and develop a skin rash. There is some hope. Efforts to destroy these plants by uprooting or by spraying chemicals have been somewhat ineffective. Caution: whatever you do, do not burn the plant. Its toxins will filter into the air, and if breathed, can cause irritation in the lungs. Not a very pleasant experience.

The oil on the leaves is known as urushiol. The urushiol compound in poison ivy is not meant as a defensive measure, but rather helps the plant retain water. It is frequently eaten by animals such as deer and bears. Statistically, about 15 percent to 30 percent of people have no allergic reaction to the urushiol. Fortunately, I fall in that category.

Once contact has been made, it takes some time for it to penetrate the skin and do damage. Before this happens, it is wise to wash the skin completely several times with plenty of soap and water. Some experts say that washing within the first hour may help limit the rash. Care should be taken not to touch any other parts of the body, for even tiny amounts of the oil will cause irritation. Also, wash the clothing immediately. If poisoning develops, the blisters and red, itching skin may be treated with dressings of calamine lotion, Epsom salts, or bicarbonate of soda. Dermatologists recommend a simple oatmeal bath and baking soda as a possible remedy. Scientists have developed a vaccine that can be injected or swallowed. But this is effective only if taken before exposure.

So, now we know a little more about poison ivy. But, always remember this: “Leaves of three, let it be.”

SCORES & OUTDOORS: There’s a mouse in the house

Roland D. Halleeby Roland D. Hallee

The house mouse is becoming more and more of a nuisance at camp, and to say the least, are not welcome. My neighbors are fighting a constant battle with them, and until Saturday, my wife and I had been free of them. They have intruded our camp and when we uncovered our boat, it became apparent they had taken up residency over the winter. The discovery of five nests, and their destructive results, was, to say the least, discouraging. We spent the better part of the day cleaning up the mess.

The house mouse is a small mammal of the rodent family, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point truly wild populations are significantly less common near human activity.

The house mouse is best identified by the sharp notch in its upper front teeth.

House mice have an adult body length (nose to base of tail) of three- four inches, and a tail length of two – four inches. The weight is typically 3⁄8 – 1 ounce. In the wild they vary in color from grey and light brown to black. They have short hair and some, but not all, sub-species have a light belly. House mice thrive under a variety of conditions; they are found in and around homes and commercial structures, as well as in open fields and agricultural lands.[9]

House mice primarily feed on plant matter, but are omnivorous. They eat their own feces to acquire nutrients produced by bacteria in their intestines. House mice, like most other rodents, do not vomit.

The social behavior of the house mouse is not rigidly fixed into species-specific patterns but is instead adaptable to the environmental conditions, such as the availability of food and space.

House mice have two forms of social behaviour. House mice in buildings and other urbanized areas with close proximity to humans are known as commensal. Commensal mice populations often have an excessive food source resulting in high population densities and small home ranges. This causes a switch from territorial behaviour to a hierarchy of individuals. When populations have an excess of food, there is less female-female aggression, which usually occurs to gain access to food or to prevent infanticide. Male-male aggression occurs in commensal populations, mainly to defend female mates and protect a small territory.

In open areas such as shrubs and fields, the house mouse population is known as noncommensal. These populations are often limited by water or food supply and have large territories. Female-female aggression in the noncommensal house mouse populations is much higher, reaching a level generally attributed to free-ranging species. Male aggression is also higher in noncommensal populations. In commensal populations, males come into contact with other males quite frequently due to high population densities and aggression must be mediated or the risk of injury becomes too great.

Both commensal and noncommensal house mouse males aggressively defend their territory.

In both agricultural and urban environments house mice are often preyed upon by the domestic catt.

House mice usually live less than one year in the wild, due to a high level of predation and exposure to harsh environments. In protected environments, however, they often live two to three years.

House mice usually live in proximity to humans, in or around houses and/or fields. They are native to India, and later they spread to the eastern Mediterranean about 13,000 BC, only spreading into the rest of Europe around 1000 BC. This time lag is thought to be because the mice require agrarian human settlements above a certain size. The house mouse first arrived in the Americas in the early 16th century. It was carried aboard on the ships of Spanish explorers and Conquistadors. About one hundred years later, it arrived in North America with French fur traders and English colonists. They have since been spread to all parts of the globe by humans.

Many studies have been done on mouse phylogenies to reconstruct early human movements. For example, one study suggests the possibility of a previously unsuspected early link between Northern Europe and Madeira on the basis of the origin of Madeiran mice. House mice were thought to be the primary reason for the domestication of cats.

However you look at it, a mouse in the house usually means some form of destructive behavior.
