Granary Weevil
A small, shiny, dark reddish-brown to black weevil with a long curved snout that is unable to fly, spending its entire life cycle within stores of wheat and other cereal grains.
beetle
American Carrion Beetle
A broad, flattened black beetle with a striking pale yellow shield behind its head, commonly found on and around small animal carcasses where it feeds alongside fly larvae.
beetle
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
Bluet Damselfly
Small and delicate, bluet damselflies flash brilliant blue and black along the vegetated edges of ponds and lakes, forming mating pairs that fly in tandem while laying eggs directly into plant stems underwater.
dragonfly
Tussock Moth
A moth with a striking split lifestyle: winged, drab gray-brown males fly to seek out flightless, grub-like females, while the ornate caterpillars sport dense tufts of colorful bristly hair.
moth
Bumblebee
A large, round, densely furry bee with bold black-and-yellow banding, known for its loud, low-pitched buzz and its ability to fly and forage in cooler temperatures than most other bees.
bee
Termite Swarmer
A dense, short-lived cloud of dark, equal-winged insects pouring from a crack in soil or wood, each one a would-be founder of a brand-new termite colony.
other
Leaf-Footed Bug
A large, elongated brown true bug named for the flattened, leaf-shaped expansions on its hind legs, often found feeding on fruits, seeds, and vegetables in gardens and orchards.
true-bug
Northern Pearly-eye
A shade-loving brown woodland butterfly with rows of dark, pale-ringed eyespots, more often seen resting on tree trunks in forest gaps than flying in open sun.
butterfly
Flower Chafer Beetle
Often clad in brilliant metallic greens, golds, and bronzes, flower chafers are day-flying scarab beetles that feed on flowers. Many buzz loudly in flight and keep their wing covers closed as they take off.
beetle
Digger Bee
A robust, fast-flying, densely furry solitary bee that excavates tunnels in bare or sloped soil, often confused with bumble bees due to its bulky, hairy build and loud buzzing flight.
bee
Wasp
A slender-waisted, smooth-bodied flying insect typically banded in black and yellow, recognizable by its narrow 'wasp waist' and folded wings, and often social, building paper nests in colonies.
wasp
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
Six-spot Burnet Moth
A day-flying moth with glossy black-green forewings marked by six bold red spots and vivid crimson hindwings, a striking warning-colored insect often mistaken for a butterfly as it visits summer wildflowers.
moth
Mosquito Larva
A wriggling, comma-shaped aquatic larva that hangs from the water's surface to breathe before transforming into a flying adult mosquito.
aquatic-insect
Blue-eyed Darner
A large, fast-flying darner with brilliant sky-blue eyes that meet in a seam across the top of the head, patrolling ponds and open fields well into the evening.
dragonfly
Gypsy Cutworm Moth
A plain, mottled grey-brown night-flying moth whose stout, soil-dwelling larvae are known as cutworms for their habit of severing young plant stems near ground level.
moth
Lubber Grasshopper
Heavy-bodied and slow-moving, lubber grasshoppers make up for their poor flying ability with large size, bold coloring, and a lumbering, ground-bound lifestyle.
grasshopper-cricket
Bumblebee Moth
A fuzzy, day-flying sphinx moth that hovers at flowers like a bee, with mostly clear wings and a black-and-yellow banded body that mimics a bumblebee.
moth
Firefly
A soft-bodied, dusk-flying beetle famous for the bioluminescent flashes it produces from its abdomen to attract mates on warm summer evenings.
beetle
Squash Vine Borer
A day-flying, wasp-mimicking moth whose orange fuzzy hind legs and metallic wings make it easy to mistake for a wasp as it darts around squash vines.
moth
Spring Azure
One of the earliest-flying small blue butterflies of spring, with soft pale-blue upperwings, a whitish gray underside dotted with faint dark markings, and no tails on the hindwing.
butterfly
Zebra Longwing
A slow-flying, long-winged black butterfly striped boldly with yellow, unusual among butterflies for feeding on pollen as an adult, which extends its lifespan to several months.
butterfly
Emperor Dragonfly
One of Europe's largest and most powerful dragonflies, a fast, high-flying hunter with a bright sky-blue abdomen in males and a commanding, tireless patrol over open water.
