Emerald Ash Borer Confirmed in Northern New York

emerald ash borer photo courtesy DECThe 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.

North Country Deerflies

deerfly 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.

Caddisflies: Submerged Silk Spinners

caddisflyA 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.

Adirondack Insects: Forest Tent Caterpillars

forest tent caterpillarWalk 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.

Biting Midges: Part of Life in the Adirondacks

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.

Adirondack Butterflies: The White Admiral

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.

Striders: Summer Insects Who Skate On Water

Water Strider 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.

Adirondack Pollinator Project Celebrating Pollinator Week

monarch butterflyThe 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.

Spring Visitors: Ladybug Beetles

ladybugAmong the many groups of insects that exist on our planet, the most abundant, diverse and ecologically successful are the beetles. And while many of these hard-shelled bugs are viewed as ugly and unwanted by humans, the ladybug beetle is considered to be one of the most attractive and environmentally friendly creatures in nature.

With a conspicuous dome-shaped, orange shell marked with black spots, the ladybug is difficult to mistake for any other invertebrate. Like all insects, there are numerous species of ladybugs that reside in our region, and the subtle differences in the color and pattern of its markings is the common means of distinguishing among the members of this insect group. » Continue Reading.

Don’t Go Out Without A Net: It’s Black-fly Season in the Adirondacks

Bug net photo of and by Tracy Ormsbee

With the blooming of the first spring flowers comes another rite of spring: black flies. Consider this a warning, since you may have a little time before they start biting, according to scientist Curt Stager, a professor at Paul Smith’s College.

“They’re out already,” he said, adding, “Often they don’t bite right away. They just swarm and see what’s on the buffet.”

And that’s us. » Continue Reading.

Before The Black Flies Come, There Are Ants

carpenter antPrior to the start of black fly season, and continuing for several weeks after the swarms of those tiny, biting demons have faded, there is another insect onslaught that impacts numerous people throughout the Adirondacks. Shortly after the soil has thawed in spring, ants begin to invade the living space of humans, especially kitchens and dining areas where bits of food are readily available.

Since there are so many types and species of ants in the North Country, it is impossible to say what kind of ant is appearing around countertops, near pantry closets, in garbage containers, and under tables where morsels of edibles lie undisturbed on the floor. However, it is easy to state that numerous ants readily welcome themselves indoors, as long as there is something worthwhile for them to collect and transport back to their colony. » Continue Reading.

Tipulidae: The Cute Faced Crane Fly

crane flyAn email chirped in my inbox; “Check out the cute face on this insect we found.” I opened the attachment (yes, from a reliable source). My colleague Professor Peter Hope had taken a spectacular photograph through his microscope. The larva in question had fallen into a pit trap set by our first-year Saint Michael’s College students in Camp Johnson in Colchester.

The ‘face’ seemed to have two very circular black eyes, a downturned smile, and a wild cartoonish hairstyle sprouting from lobes radiating in five directions. My esteemed colleague, a gifted botanist, had photographed the rear end of a crane fly larva. In fairness, any reasonable person might have made this mistake, especially because the front of the insect doesn’t look like a front, its head pulled so far back into the body as to be invisible. » Continue Reading.

A Moffitt Beach Campground Invasive Species Survey

Tom Colarusso and I teamed up for an invasive insect forest survey on a sunny, warm January day.  Tom is a Plant Protection and Quarantine Officer for the United States Department of Agriculture’s Animal and Plant Health Inspection Service.  We survey one campground a year for invasive insects, and his expertise has fueled my understanding of these hungry bugs.

We headed to Moffitt Beach Campground to check trees for hungry bugs like Asian longhorned beetle (ALB), emerald ash borer (EAB), and hemlock woolly Adelgid (HWA). » Continue Reading.

The Arthropods Among Us

Not to alarm you, but you’re surrounded.

There, buzzing stupidly into the slats of your venetian blinds, is a house fly. Nearby, nestled in a crevice of the window-frame, a ladybug waits out the winter. In a corner overhead, a spindly house spider sits motionless in its haphazard web. Underfoot, bristly little carpet beetle larvae nibble at the fibers of an old rug. And that’s to say nothing of the dust mites, which are too small to see and too numerous to count. » Continue Reading.
