Picture-Winged Fly

Picture-Winged Fly

A small fly whose clear wings are decorated with bold bands, spots, or intricate patterns, often waved and flicked in slow, deliberate displays that give the impression of a tiny fan being opened and closed. Some species even raise their patterned wings above the body and walk sideways in courtship displays reminiscent of a strutting peacock.

Creeping Water Bug

Creeping Water Bug

Broad, oval, and flattened like a tiny shield, the creeping water bug crawls methodically through submerged vegetation rather than swimming freely, using its stout, raptorial front legs to seize prey.

Toe-Biter

Toe-Biter

One of the largest true bugs in the world, the toe-biter is a broad, flattened ambush predator that lies in wait among pond vegetation, seizing prey many times its own size with powerful raptorial front legs.

true-bug
Red Velvet Mite

Red Velvet Mite

A plump, brilliant red mite covered in a dense coat of short velvety hairs, often seen emerging onto the soil surface in numbers right after a heavy rain. Its vivid color and unusual size for a mite make it one of the more eye-catching arachnids most people will ever encounter.

arachnid
Coral Hairstreak

Coral Hairstreak

A tailless hairstreak identified by a bright row of coral-red spots lining the outer margin of the hindwing underside, often seen nectaring in numbers on milkweed and butterfly weed in midsummer meadows.

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
Fishfly

Fishfly

A smaller, more modestly built cousin of the dobsonfly, often mistaken for its larger relative but lacking the dramatic elongated mandibles of male dobsonflies.

aquatic-insect
Gnat

Gnat

A catch-all common name for a wide range of tiny, delicate flies, some no bigger than a grain of pepper, often seen hovering in small clouds near water, moist soil, or overripe produce.

fly
Non-Biting Midge

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

Midge

A slender, mosquito-like fly that forms dense swarms near water at dusk, easily mistaken for a mosquito but lacking any biting mouthparts.

fly
Tortoise Beetle

Tortoise Beetle

A small, flat, disc-shaped beetle whose expanded wing covers and pronotum hide its head and legs almost entirely, giving it the look of a miniature turtle shell crawling across a leaf.

beetle
Promethea Moth

Promethea Moth

A medium-sized silk moth showing striking differences between the sexes, with dark, blackish-maroon males that mimic a distasteful swallowtail butterfly in flight and larger, more colorful reddish-brown females marked with pale borders and eyespots.

moth
Harvestman

Harvestman

An arachnid built almost entirely of legs, with a single compact, oval body segment and no waist separating it into two parts like a true spider. Common in gardens and forests worldwide, it scuttles along on impossibly long, thin legs scavenging for food after dark.

arachnid
Caddisfly Larva

Caddisfly Larva

A soft-bodied aquatic larva famous for building a portable protective case from sand, gravel, or plant debris bound together with silk.

aquatic-insect
White Grub

White Grub

A pale, C-shaped larva with a brown head capsule and six stubby legs, spending its entire early life hidden underground feeding on roots before emerging as a stout May or June beetle.

beetle
June Bug

June Bug

A chunky, reddish-brown to nearly black scarab beetle that bumbles noisily around porch lights on warm late-spring and early-summer evenings.

beetle
Rove Beetle

Rove Beetle

A slender, fast-running beetle with unusually short wing covers that leave much of its flexible abdomen exposed, often curling its tail upward like a scorpion when alarmed.
