Deer tick, left, and engorged, right.

by Roland D. Hallee

There is nothing like beating a subject to death. But, in this case, it’s worth every word.

You have to be living in a cave not to know that deer ticks are at an all time high. They are everywhere. Friends and family have told me stories about their encounters with the insect, and they all have one thing in common. They have all had multiple numbers on them at one time.

Also, as you know, deer ticks are hazardous to your health, primarily because they are the carriers of the dreaded Lyme Disease. In the last decade alone, the population of ticks of all kinds has ballooned in the United States. The number of ticks that carry Lyme disease has been on the rise in the mid-Atlantic states, and has skyrocketed throughout the Northeast. It has gained a reputation as a serious health problem in many areas.

On top of that, with most of us trying to get outdoors this time of year (opening camps is a real concern), and with the recent mild winter we experienced, the deer ticks are already active and will be out in force this summer.

Only adult female ticks and nymphs can transmit infections through their bite. Male ticks attach, but they don’t feed or become engorged. Adult females have red and brown bodies and are larger than males. Nymphs are actively feeding between early April and early August.

Although not all deer ticks are infected with Lyme disease, you never really know. Only ticks that have fed on infected mammals are diseased. About half of deer ticks are infected (usually white-footed mice can be other culprits).

Deer ticks live two to three years, and in that time usually enjoy three blood meals. In the spring and summer of its second year, a nymph will take its second meal. They insert their mouth parts into the skin much like a corkscrew, which ensures them a nice tight grasp. They often take up to five days to complete their meal.

This fact is key to reducing panic when discovering a tick. An infected tick must be attached to its host for at least 24 hours, and up to 48 hours to transmit the disease. It’s the very reason for checking your body right away after any possible exposure to a tick-infested environment.

Deer ticks crawl. They usually grab onto people or animals that brush up against plants near ground level, and then they crawl upwards to find a quiet place for their blood meal ­– the inner thigh and in the hair line behind the neck are a couple of “favorite” spots. Although many sources will state that ticks don’t land on you from an overhanging tree branch, many people have insisted it has happened to them.

Ticks live in wooded, brushy areas that provide food and cover for mice, deer and other mammals. The ideal tick environment is humid. Your exposure will be greatest along trails in the woods and fringe areas between woods and the border, where they will wait patiently on the tips of vegetation for an unsuspecting host to walk by.

Life is too short to avoid the outdoors during our short spring, summer and fall. In Maine, that is about half the year. There is no need to be brave, just be smart: cover your body; wear repellant; check yourself for ticks, if you find a tick, remove it immediately; shower soon after being outdoors; throw clothing in the dryer, that will kill any ticks present; and finally, if you are concerned, don’t hesitate to contact your doctor.

The best way to remove a tick is to use fine-point tweezers and grab the tick as close to the skin surface as possible. Pull backwards gently but firmly, using an even, steady pressure. Do your best not to jerk or twist. Don’t squeeze, crush or puncture the tick’s body, the fluids inside may contain infection-causing organisms. After removing the tick, wash the skin and your hands thoroughly with hot soap and water. If any mouth part of the tick remain in the skin, leave them alone. They will be expelled on their own. It could take weeks. Trying to remove them will only cause you unnecessary pain.

For the deer tick, Ixodes scapularis, deer are the preferred host, but they can also be found in small rodents. After the female is engorged, the tick drops off and overwinters in the leaf litter of the forest floor. The following spring, she will lay several hundred to a few thousand eggs in clusters. They are very hardy creatures. They will be active even after a moderate to severe frost, as daytime temperatures can warm them enough to keep them actively searching for a host. In the spring, they are one of the first invertebrates to become active.

It may be monotonous to keep hearing about the health hazards of being infected by a deer tick, but it’s one that needs to be repeated.

Snowy tree cricket

by Roland D. Hallee

Over the last 50 years or so of my adult life, I have been involved in many activities, including coaching sports at the youth and high school levels, and have done my share of local political participation. So, in exposing myself to critics, I have been called some unflattering names. Some more colorful than others. But, one thing of which I have never been accused is being a nerd.

So, with that, I must make a confession. Although skeptical at first, I have become a follower of the now defunct TV sitcom, The Big Bang Theory. That group of nerds deals solely in science, and very rarely on practicality. My original evaluation of the show was that no one could be that nerdy. So, in one recent rerun episode, Sheldon, the “top” nerd of the group, talked about the Snowy Tree Cricket.

That was a good one. Who made up that name? It sounds contrary to anything about crickets I know. Well, I looked it up, and sure enough, it actually exists.

This is what I found. The snowy tree cricket, Oecanthus fultoni, also known as the thermometer cricket, is a species of tree cricket from North America. It feeds on leaves but also damages fruit. The chirp of this species is often dubbed onto sound tracks of films and television shows to depict a quiet summer’s night, or ridicule from an audience attending a comic’s show when they don’t think the joke was funny. The rate of chirp varies depending on the heat of the environment, allowing a listener to estimate the temperature.

The cricket’s common name of the thermometer cricket is derived from a relationship between the rate of its chirps and the temperature. An estimate of the temperature in Fahrenheit can be made by adding 40 to the number of chirps made in 15 seconds. Before 1960, the name Oecanthus niveus was wrongly applied to this species. Oecanthus fultoni was named in honor of Bentley Ball Fulton (1880 – 1960), an American entomologist who laid the principal groundwork on North American cricket classification.

Of course, if you are really interested in using the snowy tree cricket as a thermometer, you should calibrate your local crickets against a thermometer placed near where they sing. Count their chirps per minute at a variety of temperatures, graph the results, draw a line that fits the points, and use a little algebra to arrive at a handy formula.

The species is about a half inch long and is light green with translucent light green wings. It has black marks on the first and second antennal segments, that are either round or oval shaped, and is about half the length of a segment. The antennae are longer than its body and it has a small head. The eggs are pale yellow and shaped like a kidney. Its nymphs are pale and slender with wings that are not completely developed. The nymphs develop wings slowly. It has one generation per year.

American novelist Nathaniel Hawthorne said of the species’ chirps, “If moonlight could be heard, it would sound just like that.”

The species can be found throughout the United States except the southeastern part of the country. In Maine, they are predominantly in York and Cumberland counties. It is located in shrubs, vines, fruit trees, broad-leaved trees, and oaks. The cricket can rarely be found in grass. Adults of the species can be found from mid-July to mid-November. The cricket can sometimes be so high in oak trees that its chirp is the only way to identify it.

Both nymphs and adults feed on leaves and their feeding causes barely any damage. The cricket is known to destroy apples, plums, peaches, and cherries. The female drills a hole into a twig’s cambium in which to lay its egg. It then makes a row of punctures on one side of the hole and seals it with either excrement or chewed plant tissue once the egg is placed. Adults of the species eat holes in ripe fruits which results in the fruit rotting. It normally does not cause any damage in orchards that are consistently sprayed.

There is yet more to know about the song of the snowy tree cricket. Although Sheldon talked about it, the cricket never did make an appearance.

Not quite the whole show

Well, I caved in. At first showing no interest in the solar eclipse that occurred on April 8, a colleague came into the office with some extra pairs of viewing glasses. My curiosity took over.

I sat outside for approximately 25 minutes, and from my vantage point in China, I witnessed what I would classify as a 98.5 percent eclipse. In that 25 minutes, it never came to totality.

Oh well, there’s always 2044.
