Some invasive insects appear to be trying to win us over through sly public-relations moves. Emerald ash borer (EAB), the Asian beetle killing our ash trees, arrived looking like it just came from a Mary Kay convention, all bright, glitzy and glitter-coated. And it could have been simply called the green ash borer, but instead managed to get itself branded “emerald,” something everyone likes.
A new forest pest on the horizon seems to have taken a page from EAB. Trichoferus campestris, better known as the velvet longhorned beetle, has cleverly brought the cuddliness of the Velveteen Rabbit and the romantic image of Texas Longhorns together in its name. Don’t be fooled by this brilliant strategy, though. Let’s pull back the curtain and expose the velvet longhorned beetle (VLB) for what it really is. » Continue Reading.
I had just finished my safety talk to some middle school students when I heard a bloodcurdling scream. In many years handling aquatic insects and other small water creatures, I have never been wounded. Crayfish have once or twice gotten hold of me but never drawn blood. So I was quite surprised to hear through the minor chaos that a student had actually been bitten.
There were no crayfish where we sampled in Winooski, Vermont floodplain ponds and only one likely candidate to produce such a scream. It was the reason I had specifically warned my students to use forceps. » Continue Reading.
Excessive tinder is a major contributor to forest fires, but a shortage of Tinder can lead to an early death. For social animals like canines, deer, dolphins, elephants, primates such as bonobos and humans, and even bees and ants, contact with others is as essential to well-being as food and water.
A 2015 study done at Brigham Young University which garnered much news coverage in 2017 and early this year found that loneliness may be a greater health risk than smoking and obesity combined. » Continue Reading.
So here’s my movie concept: during a laboratory accident, a scientist exchanges his DNA with a fly. Over the next few weeks, our hero slowly shrinks in size and transforms into an insect with black spiky body hair, maroon eyes, and translucent, buzzing wings.
What distinguishes this movie from previous versions of “The Fly” is that this time, the scientist swaps his genes with a cluster fly. Instead of developing super-fast reflexes, he becomes clumsy and lethargic. Instead of rampaging through a city terrorizing people, he alternates his time between crashing against the window and lying upside-down on the floor, twitching. The crisis comes when his irritated girlfriend picks him up with a tissue and tosses him outside. He soars into the clear blue winter sky… but then his wings freeze. The final image: a tiny crater in the snow. » Continue Reading.
A few Thanksgivings ago, my then-ten-year-old daughter and I went for an afternoon stroll. Unseasonably warm weather made for a longer than planned walk through a power line right-of-way and on down through steeply sloping woods to the Winooski River. As we moved through the tall scrub, Lauren’s interest was drawn to the golf ball-sized swellings on desiccated goldenrod stalks.
As usual, she had many really good questions: what were these woody spheres on dead plants; why did some have holes; what did they look like inside? We pocketed a few and continued our walk. The soft silty river bank was peppered with footprints left by raccoons, herons, skunks, and deer that prompted more questions. By sunset we had made it through the Muddy Brook Natural Area and back out onto the gravel road. Our catch of the day remained in our pockets until after dinner. » Continue Reading.
This time of year, I keep the windows cracked open on even marginally warm nights, savoring the sweet air that sifts through the screens. On that air comes the sound of others relishing the last bit of warmth before frost settles in: namely, crickets and katydids.
With trills and chirps, clicks and buzzing, these winged insects – all members of the order Orthoptera, along with grasshoppers – woo potential mates. This music is ancient – and has been a key to the insects’ survival for some 200 million years. » Continue Reading.
The Adirondack Park is tinted with a new hue of brown this past week, and not from the changing foliage of deciduous trees for winter. The painted lady butterfly with its cinnamon orange wings outlined by mocha appendages is making moves South for what is seemingly the “most massive migration since the ’80’s” as Chip Taylor of Monarch Watch claims.
Commonly mistaken for the monarch butterfly because of the similar coloration, the painted lady finds residence on all continents except for Australia and Antarctica. In the United States, extremely well breeding populations are found in the North, West and Eastern regions. Taylor said he is receiving “reports from Montreal to the Front Range of Colorado [that] entail the mid-continental migration of possibly billions of painted lady butterflies” this year. » Continue Reading.
The New York State Department of Environmental Conservation (DEC) has announced that invasive pest emerald ash borer (EAB) has been found and confirmed for the first time in Franklin and St. Lawrence counties. DEC captured the insects in monitoring traps at the two locations.
DEC confirmed the specimens as adult EABs on August 25. The invasive pest was found within a few miles of the Canadian border and may represent an expansion of Canadian infestations into New York. » Continue Reading.
My students and I were conducting research in the Winooski River floodplain at Saint Michael’s College last week when the buzzing became particularly intense. A brisk walk is enough to outdistance mosquitoes, but deerflies combine fighter jet speed with helicopter maneuverability. And a slap that might incapacitate a mosquito seems to have little effect on these relentless pests. Deerfly season 2017 started slowly, but by late July there were enough to carry off small children. On trails between wetlands and farm fields, we were dive-bombed by countless, persistent, little winged vampires. Insect repellent did little to repel them. We slapped, feinted, grabbed at thin air, and usually came up empty. It was like Caddyshack, but with flies rather than gophers.
The horsefly family Tabanidae includes deerflies, along with larger Alaskan “mooseflies,” and the greenheads that ruin many a trip to New England’s beaches. Iridescent green eyes that make up most of the fly’s head give them their common name. Far more impressive is their bite: they truly hurt. Because greenheads emerge only from saltmarshes, we know they travel up to two miles in search of blood. » Continue Reading.
A small boy asked “what’s your favorite insect?” I answered without hesitation: caddisflies. Not the short-lived adults, which while charming in their own hairy moth-like way, do not capture my attention. My caddisfly predilection is reserved for the larval stages that last for most of the insect’s one or, less often, two or three year life span. These larvae, like their caterpillar cousins, make and use silk in ways that fascinate me. Silk permits their use of a wide variety of freshwater habitats and food sources.
Consider the caddisflies of the family Rhyacophilidae. Their name translates to “rock loving,” and this preference serves them well in fast-flowing streams. They spin silk ropes that anchor firmly to rocky surfaces, helping them to defy the pull of currents, and stay off some trout’s dinner menu. Like ice climbers using crampons, they also have impressive claws that grow right out of their rear ends. Their anal claws and silk lines keep their bulging, segmented, Michelin-Man bodies secured while they scramble about, eating insects including other caddisflies. » Continue Reading.
Walk through a hardwood forest this month and it may seem more like October than July. Trees that normally provide cool shade have bare crowns with just a hint of green. And is the bark on that sugar maple moving? This is not a trick of the light: you are, in fact, in the middle of a forest tent caterpillar outbreak.
Despite the name, forest tent caterpillars don’t actually build tents like their cousins the eastern tent caterpillars. Instead, you’ll find them congregated on silken mats on tree trunks or branches. If you’re in an infested area, they won’t be hard to find. Sugar maples and aspen are often the favorite host species in the Northeast, as well as birch, cherry, basswood, and ash. » Continue Reading.
A screened-in porch is an ideal place to relax on a summer evening in the Adirondacks. 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 backwoods ambiance of that peaceful Adirondack evening. Biting midges are small enough to pass through traditional screens, allowing them access to any individual wanting to enjoy the evening.
The biting midges form a large group of exceedingly small true flies that are roughly the size of a sand grain, and are known to many as punkies or no-see-ums. The latter common name comes from this bug’s ability to remain unseen in low light conditions, such as on a porch after sunset, even when one of these pests has started to chew into your skin. Despite their dark color, no-see-ums are still a challenge to see clearly, even when standing against a patch of light colored skin. On a person with a dark complexion, punkies can be impossible to spot, regardless of how good the light may happen to be. » Continue Reading.
Forest clearings in the Adirondacks are especially attractive settings for many forms of wildlife. The warmth of the ground when the sun is shining is particularly inviting to cold-blooded creatures, and the stands of trees that surround these openings in the canopy serve as a source of food and shelter.
Clearings created during logging operations, wide sections along secondary roads, and the open space that typically exists around lean-tos and campsites are places frequented by numerous animals. Among the creatures easily observed during the coming month in these sunny oases of our deciduous and mixed woodlands is a strikingly attractive, black butterfly with a distinct white strip across its wings. The white admiral butterfly (Limenitis arthemis) is a common component of our fauna and regularly lingers around small forest clearings during the early summer throughout the Park. » Continue Reading.
Scanning a sunlit pond floor for crayfish, I was distracted by seven dark spots gliding in a tight formation. Six crisp oval shadows surrounded a faint, less distinct silhouette. The shapes slid slowly and then, with a rapid motion, accelerated before slowing to another glide. I can remember seeing this pattern as a child, in my first explorations of pond life.
Water strider shadows are far larger than the insects casting them. To visualize the surprising proportion of legs to body, it may help to think in human scale. For mathematical simplicity, picture a six-foot-tall man lying flat on the water surface. Imagine that attached near his hips he has a pair of seven-foot-long, stick-skinny legs pointing back at a 45 degree angle. Just forward of these spindles he has another pair pointing forward at a 45 degree angle; these are nine feet long. A pair of three-foot-long arms point forward and each has a single claw protruding from the palm. » Continue Reading.
The Adirondack Pollinator Project (APP) is a new initiative of AdkAction in partnership with The Wild Center, The Lake Placid Land Conservancy, and Common Ground Gardens, that features an extensive program of educational activities and events throughout the summer. The program will kick off at area farmers’ markets and The Wild Center during National Pollinator Week, June 19-25th.
Film showings, hands-on beekeeping, gardening and citizen science workshops, and free public lectures by pollinator researchers are planned throughout the Adirondacks to help inspire individual and collective action to help pollinators thrive. Highlights of the programming are two free public lectures from Dr. Christina Grozinger, Director of the Center for Pollinator Research at Penn State University, at The Wild Center on July 19th and at View Arts in Old Forge on July 20th. » Continue Reading.
