Deer Tick
A small, dark-legged tick with a reddish-brown, teardrop-shaped body, noticeably smaller than many other common tick species and often found questing in wooded or grassy edge habitats.
arachnid
Burying Beetle
A black beetle marked with bold orange-red bands, notable for locating small dead animals, burying them underground, and cooperatively raising larvae with a partner over the buried carcass.
beetle
Vivid Dancer
A brilliant violet-blue damselfly of western streams, the Vivid Dancer is one of the most striking members of the dancer genus and is notably tolerant of warm, mineral-rich waters.
dragonfly
Spotted Wing Drosophila
A tiny reddish-brown fruit fly, each male marked with a single dark spot near the wingtip, notable for laying eggs in ripening rather than overripe fruit.
fly
Black Vine Weevil
A flightless, all-black snout beetle notorious for notching the edges of leaves at night while its underground larvae feed on plant roots and crowns.
beetle
Japanese Beetle
A small, iridescent beetle with a metallic green head and thorax and coppery-bronze wing covers, notorious for skeletonizing the leaves of roses, grapevines, and hundreds of other garden plants.
beetle
Bumble Bee Queen
The large, robust foundress of a bumble bee colony, noticeably bigger and fuzzier than her worker offspring, seen alone in early spring searching for a nesting cavity before her colony's first workers emerge.
bee
Darkling Beetle
A uniformly dark, matte-black ground beetle often seen walking deliberately across open soil, known for tilting its rear end skyward in a distinctive defensive posture when disturbed.
beetle
Longhorn Bee
A fuzzy, medium-sized solitary bee named for the males' notably long, curved antennae, commonly seen foraging on sunflowers, asters, and other late-summer composite flowers.
bee
Ruby Meadowhawk
A small, brilliant-red dragonfly of late summer meadows, so intensely colored that mature males seem to glow when perched low in the grass.
dragonfly
Red-spotted Purple
A large, iridescent blue-black butterfly lacking tails, notable for closely mimicking the unpalatable Pipevine Swallowtail, with rows of red-orange spots visible along the underside wing margins.
butterfly
Mourning Cloak
A dark, velvety maroon-brown butterfly edged with a ragged cream-yellow border and a row of iridescent blue spots, notable for overwintering as an adult and often being one of the very first butterflies seen flying in early spring.
butterfly
Hackberry Emperor
A brown-and-cream butterfly closely tied to hackberry trees, notable for its bold eyespots and habit of landing on people, cars, and other unusual surfaces rather than flowers.
butterfly
Blue Morpho Butterfly
A dazzling, hand-sized rainforest butterfly whose wings flash brilliant metallic blue in flight, an effect created not by pigment but by microscopic light-bending scales.
butterfly
Fall Armyworm
A brownish-green caterpillar marked with a pale inverted "Y" on its head, notorious for rapid, large-scale outbreaks that devastate corn and other grass crops across the globe.
caterpillar-larva
March Fly
A stout, all-black fly that emerges in sudden, dense swarms during the first warm days of spring, often dangling its long hind legs conspicuously in slow, low flight over grass. Its name comes from its habit of appearing reliably around the start of the month, sometimes on cue near a particular saint's feast day in the traditional European calendar.
fly
Common Whitetail Dragonfly
A stocky pond-side dragonfly whose mature males sport a broad, chalky white abdomen that flashes conspicuously against boldly banded wings.
dragonfly
Fall Webworm
A pale, hairy caterpillar that spins loose, messy silk webs enclosing entire leaf clusters at the tips of tree branches, becoming especially noticeable in late summer and fall.
caterpillar-larva
Whitefly
A tiny, moth-like white insect that clusters on the undersides of leaves and bursts into a snowy cloud when the plant is disturbed. Despite the name, it is not a true fly but a sap-feeding relative of aphids and scale insects.
true-bug
Hornet
A large, robust social wasp with a reddish-brown and yellow patterned body, notably bigger than yellowjackets, building enclosed papery nests often high in tree cavities or wall voids.
wasp
Devil's Coach Horse Beetle
A large, matte-black rove beetle that raises its flexible abdomen up and over its back like a scorpion's tail and gapes its jaws when threatened, one of the biggest and most dramatic rove beetles in Europe.
beetle
Grub Worm
A plump, C-shaped, creamy-white larva with a distinct brown head, living underground where it feeds on grass and plant roots before eventually maturing into a scarab beetle.
beetle
Powdered Dancer
Named for the pale, frosty bloom that coats mature males, the Powdered Dancer is a robust river damselfly often seen basking on sunlit rocks and gravel bars.
dragonfly
Lanternfly (Spotted Lanternfly)
A strikingly patterned planthopper with grey, spotted forewings that flash to reveal crimson hindwings when it leaps, now notorious as an invasive agricultural pest far from its native range.
