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.

Tussock Moth

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

Madagascan Sunset Moth

Madagascan Sunset Moth

A day-flying moth with iridescent wings that shimmer through bands of green, blue, red, and gold, so vividly colored that it is frequently mistaken for a butterfly despite being a true moth.

moth
Dragonfly Nymph

Dragonfly Nymph

A stocky, camouflaged underwater predator that spends months or years stalking prey along the pond bottom before transforming into an aerial dragonfly.

aquatic-insect
Angle Shades Moth

Angle Shades Moth

A common night-flying moth whose forewings fold into a crumpled, tent-like shape that mimics a withered or damaged leaf, marked with bold olive-green and pinkish-brown zigzag bands.

moth

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
Fishfly Larva

A flattened, armor-plated predator of stream bottoms, the fishfly larva spends one to three years underwater seizing prey with sickle-shaped jaws before briefly taking wing as a short-lived winged adult.

aquatic-insect
Vaporer Moth

Vaporer Moth

A tussock moth with dramatic sexual differences: the male is a small rusty-brown day-flying moth with a white wing spot, while the female is a flightless, wingless gray sac-like insect that never leaves her cocoon.

moth
Non-Biting Midge Larva (Bloodworm)

Non-Biting Midge Larva (Bloodworm)

Wriggling through soft bottom mud in dense colonies, the bloodworm gets its striking red color from a specialized blood pigment that lets it survive in oxygen-poor water where few other insects can.

aquatic-insect
Vapourer Moth

Vapourer Moth

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
Flower Chafer Beetle

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
Mourning Cloak

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
Squash Vine Borer

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
Glowworm Beetle

Glowworm Beetle

A beetle whose females remain larva-like and glowing for their entire lives, producing rows of soft greenish light along their segmented, worm-like bodies, while males develop into small, feathery-antennaed flying beetles.

beetle
Meadow Fritillary

Meadow Fritillary

A small, fast-flying orange-and-black fritillary of open grassy fields, easily told from its larger cousins by its lack of silvery spots on the underside of the hindwing.

butterfly
Six-spot Burnet Moth

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.

Emperor Moth

A striking silk moth with a large eyespot on each of its four wings, showing pronounced differences between the smaller, orange-brown, day-flying males and the larger, greyer, night-flying females.

moth
Red Admiral

Red Admiral

A fast-flying, strikingly patterned butterfly with velvety black wings crossed by a bold orange-red band and white-spotted tips, often seen basking on tree trunks or sipping from fallen fruit.

butterfly
Silver Y Moth

Silver Y Moth

A fast-flying, day-active noctuid moth named for the metallic silver Y- or gamma-shaped mark on each mottled grey-brown forewing, famous for its long-distance migratory flights.

moth
Digger Bee

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.
