After several days without a significant rain, an observant gardener pulling up clumps of weeds, or a perceptive hiker traveling through a pine forest or a meadow near a stand of conifers may notice a glob of saliva-like fluid attached to a wildflower stalk or the stem of a piece of grass.

19th Century Tales Of Cabbage Worms
In Ray Bradbury’s 1952 science fiction story A Sound of Thunder, Eckels, a time-traveling safari hunter accidentally steps on a butterfly during prehistoric times, which triggers a massive change to the eco-system when Eckels returns to 2055 society.
If it’s so that a single action can have consequences centuries later, I wonder about ramifications from the mass extermination of butterflies by a witty, well-meaning, 19th century Hague (on Lake George in Warren County) cabbage farmer. [Read more…] about 19th Century Tales Of Cabbage Worms
The Northeast’s Lymantria dispar Outbreak
Occasionally I get an email from a camp, school, or even my local Rotary asking if I can present a program on insects. So it was not unusual last week for me to be handing insect nets to excited Cub Scouts. I led them toward some ash trees and made sure each Scout had an insect to examine under the microscope. Our field trip ended beneath a maple, where a parent had pointed out a profusion of caterpillars. [Read more…] about The Northeast’s Lymantria dispar Outbreak
Science Behind Our Gypsy Moth Caterpillar Outbreak
This spring, there has been larger-than-usual gypsy moth populations and leaf damage in several parts of New York State. Gypsy moths are non-native but are naturalized, meaning they will always be around in our forests.
Their populations spike in numbers roughly every 10 to 15 years, but these outbreaks are usually ended by natural causes such as disease and predators. Because of this, the State typically does not manage them and does not provide funding for treating gypsy moths on private property.

Insectivorous Plants: Sundews
In 1860, a year after publication of his seminal work on the origin of species, Charles Darwin wrote to a friend, “At the moment, I care more about Drosera than the origin of all the species in the world.”
Darwin maintained a lifelong fascination with carnivorous plants, including members of the genus Drosera, collectively called sundews. His research into these fascinating species led to the 1875 publication of Insectivorous Plants, which remains a major reference work today. [Read more…] about Insectivorous Plants: Sundews
New York Insects: Paper Wasps
While working around the home this summer, it is not unusual to notice the papery nest of a wasp tucked under the eaves, hidden behind a loose shutter, or placed in some other protected spot. While an encounter with this type of structure may temporarily disrupt a painting project or repair work, such a sanctuary is vital to the summer success of these familiar yellow and black insects, and should be left alone if at all possible as wasps play a role in helping to control the populations of numerous insects, spiders and other bugs.

Web of Mystery: Euonymus Caterpillars
Janet Hayward Burnham, of Bethel, Vermont, was driving to the bank one day when she saw a tree on the side of the road that looked like it was covered in decorative webbing, “cans and cans” of it, as if for Halloween. However, it was June. [Read more…] about Web of Mystery: Euonymus Caterpillars
The Hardy Bumble Bee
Shortly before apple blossoms open and honeysuckle flowers emerge from their buds, queen bumble bees awaken from their winter dormancy and begin the chore of establishing the small colony over which they will reign throughout the coming growing season. [Read more…] about The Hardy Bumble Bee
Bug Season: Biting Midges
A screened-in porch is an ideal place to relax on a summer evening. The tight, wire mesh that covers the walls allows the enjoyment of nature’s unique fragrances and wildlife sounds without the harassment of mosquitoes and other flying nocturnal pests.
However, during the early parts of summer, there is one bug that can detract from the ambiance. Biting midges are small enough to pass through traditional screens, allowing them access to any individual wanting to enjoy the evening. [Read more…] about Bug Season: Biting Midges
Flight Control Science of Flies
On sunny, warm days, house flies hatch and buzz around homes and offices. These flies complete aerobatic stunts that easily evade human efforts at swatting or shooing. That aerial agility, so frustrating to the would-be swatters, is thanks to a pair of highly specialized sense organs called halteres. [Read more…] about Flight Control Science of Flies
