true-bug
Bordered Plant Bug
A dark, oval-bodied true bug with a distinct pale margin around its wing edges, often mistaken for a large ant or beetle when its nymphs cluster together in tight groups.
true-bugDigger 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
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

A small tussock moth with striking sexual dimorphism: rusty-orange, day-flying males with feathery antennae contrast with flightless, grub-like grey females that never leave their cocoon to lay eggs.
moth
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.
butterflyGlowworm Beetle

beetle
Non-Biting Midge
A mosquito look-alike that gathers by the thousands in swirling mating swarms near lakes and ponds, despite lacking any ability to bite.
fly
Midge
A slender, mosquito-like fly that forms dense swarms near water at dusk, easily mistaken for a mosquito but lacking any biting mouthparts.

Giant Asian Mantis
A bulky, leaf-green predator that sits patiently among foliage, its powerful spined forelegs poised to snatch any insect that strays too close.
mantis-stick
Cloudless Sulphur
A large, bright lemon-yellow butterfly that flies with strong, direct wingbeats and rarely shows any dark markings, giving it an almost uniformly 'cloudless' appearance.
butterflyIronclad Beetle
A slow-moving, mottled gray beetle famed for having one of the hardest, most crush-resistant exoskeletons of any insect, often found clinging motionless to dead wood or tree bark.
beetle
Screech Beetle
This small, oval water beetle earns its name from the loud squeak it produces when picked up, a sound made by rubbing internal body parts together rather than by any vocal organ.
beetleTsetse Fly
A stout grayish-brown fly of African woodlands whose rigid, forward-jutting proboscis and scissor-folded wings set it apart from any ordinary house fly.
flyCone-headed Katydid
A large, grass-colored katydid named for its sharply pointed, cone-shaped head, best known for producing some of the loudest, most sustained buzzing calls of any North American insect.
grasshopper-cricket
Twenty-plume Moth
A tiny, unusual moth whose wings are each divided into numerous slender, feather-like plumes rather than solid membranes, giving it a delicate, fringed appearance unlike almost any other moth.
