Walking Stick

Walking Stick

A remarkably twig-like insect with a long, slender, brown to green body and thin legs, so effective at mimicking a plant stem that it can be nearly invisible while motionless on vegetation.

Malachite Butterfly

Malachite Butterfly

A large tropical butterfly named for the vivid green, mineral-like patches that break up its otherwise dark brown wings, giving it a translucent, stained-glass appearance in flight.

butterfly

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
Common Baskettail

Common Baskettail

One of the earliest dragonflies to appear each spring, this brown, green-eyed skimmer often swarms in numbers over sunny clearings before most other species have emerged.

Predatory Stink Bug

Unlike its plant-feeding relatives, the predatory stink bug is a hunter that spears caterpillars and beetle larvae with a stout beak. The spined soldier bug is a familiar shield-shaped garden ally.

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
Falcate Orangetip

Falcate Orangetip

An early-spring white butterfly whose males flash bright orange wingtips, while both sexes show a distinctive hooked (falcate) forewing shape and marbled green underside pattern.

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.

moth
Gypsy Moth (Spongy Moth)

Gypsy Moth (Spongy Moth)

A strongly sexually dimorphic moth, recently renamed the Spongy Moth for its distinctive spongy, tan egg masses, whose caterpillars are known for periodically defoliating oak and other hardwood trees in large outbreak years.

moth
Fall Webworm Moth

Fall Webworm Moth

A plain white (sometimes lightly speckled) moth whose caterpillars are far more familiar than the adult, spinning large communal silk webs over the ends of tree branches in late summer and early autumn.

moth
Fork-tailed Bush Katydid

Fork-tailed Bush Katydid

Slimmer and greener than its treetop relatives, the fork-tailed bush katydid lives among shrubs and garden plants, with males identified by the distinctive forked appendages at the tip of the abdomen that give the species its name.

grasshopper-cricket
Bold Jumping Spider

Bold Jumping Spider

A stocky, fuzzy black spider with iridescent green or blue mouthparts and a bold white or orange spot on its abdomen, the bold jumper is known for its excellent eyesight, curious behavior, and ability to leap many times its own body length.

spider
Screwworm Fly

Screwworm Fly

A metallic blue-green blowfly whose larvae are unusual among maggots for feeding on living tissue rather than carrion, drawn to even small open wounds on warm-blooded animals. The species has been the target of one of the most successful large-scale insect eradication campaigns in history across much of North America.

fly
Tachinid Fly

Tachinid Fly

A bristly, house-fly-like insect that looks unremarkable at a glance but hides one of the most important ecological roles among flies: its larvae develop as internal parasites of caterpillars, beetles, and other insects, quietly regulating populations across the landscape. Gardeners often welcome tachinid flies as natural allies against crop-damaging pests.

fly
Drinker Moth

Drinker Moth

A stout, furry moth with warm tawny-orange to buff-brown wings marked by two small white spots on each forewing, named for its caterpillar's habit of drinking water droplets from grass blades.

moth

Horse Fly

A stout, fast-flying fly with large iridescent eyes and a heavy, robust body, known for its persistent, buzzing pursuit of large mammals on warm summer days.

fly
Aphid

Aphid

A tiny, soft-bodied, pear-shaped insect that clusters in dense colonies on plant stems and leaf undersides, feeding on sap through needle-like mouthparts and often coated in sweet honeydew.

true-bug
Whitefly

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
Jewel Bug

Jewel Bug

A living gemstone of the insect world, the jewel bug shimmers in dazzling metallic greens, blues, reds, and golds. Its enlarged shield-like back covers the entire body, making it look like a polished piece of enamelware.

true-bug
Lime Hawk-Moth

Lime Hawk-Moth

A stout, angular-winged hawk-moth in muted greens, browns, or pinks with deeply scalloped wing margins, closely tied to lime (linden) trees for its larval development.

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

Birdwing Butterfly

Among the largest butterflies on Earth, birdwings soar through rainforest canopies on angular, bird-like wings. Males dazzle with iridescent greens, golds, and blues, while the larger females wear more subdued browns.

butterfly
Face Fly

Face Fly

A house fly look-alike that clusters persistently around the eyes, muzzle, and face of grazing livestock to feed on moisture and secretions.

fly

Dobsonfly

A massive, primitive-looking insect whose males brandish absurdly long, curved mandibles used for wrestling rivals rather than for feeding.
