Wandering Glider
One of the most widely traveled insects on Earth, this golden dragonfly rides high-altitude winds across oceans and continents, rarely landing as it forages endlessly on the wing.
dragonflyGreen Lacewing
With delicate pale green wings and glittering golden eyes, the Green Lacewing is a familiar garden insect whose larvae are voracious predators of aphids and other soft-bodied pests.

Broad-Bodied Chaser
A stout, flat-bodied dragonfly that is often the first to colonise a new garden pond, with males showing a powdery pale blue abdomen and females a warm golden-brown one.
dragonfly
Western Honey Bee
The familiar golden-brown, fuzzy-banded honey bee kept worldwide for honey production and crop pollination, living in large perennial colonies built around wax comb and a single egg-laying queen.
bee
Fox Moth
A stout, reddish-brown moth with a pale diagonal band across each forewing, closely resembling a fox in color, most often noticed as its large, densely furred dark caterpillar basking on open ground in spring.
mothAntlion
An insect best known for its larval stage, the doodlebug, which digs a small conical pit trap in loose sand to ambush unwary ants, while the winged adult resembles a slender, delicate damselfly.
otherFirefly
A soft-bodied, dusk-flying beetle famous for the bioluminescent flashes it produces from its abdomen to attract mates on warm summer evenings.
beetle
Boll Weevil
A small, grayish-brown snout beetle with a long, curved rostrum, historically famous for its close feeding association with cotton flower buds and bolls.
beetle
Seven-spotted Ladybird
A classic bright red ladybird with exactly seven black spots, one of the most iconic and widely recognized beetles in the world.
beetle
Vine Weevil
A slow, flightless, matte-black beetle that hides by day and emerges at night to notch neat semicircular bites from the edges of leaves.
beetle
Emerald Ash Borer
A slender, bullet-shaped beetle with brilliant metallic-green coloring, whose bark-tunneling larvae feed almost exclusively within ash trees.

Two-Spotted Stink Bug
A boldly patterned black-and-orange predatory stink bug named for the pair of dark spots on its back, best known for hunting Colorado potato beetle larvae in gardens and fields.
true-bugFireflies (Lightning Bug)
A soft-bodied beetle that turns summer evenings magical by flashing rhythmic patterns of cold light from its abdomen to attract mates across meadows and forest edges.
beetle
Spined Soldier Bug
A predatory stink bug identified by the sharp, pointed spines projecting from its shoulders, valued in gardens and farm fields for hunting caterpillars, beetle larvae, and other pest insects.
true-bug
Cottonwood Borer
A large, boldly patterned longhorn beetle in black and chalky white checkerboard markings, often found clinging to the trunks of cottonwood and poplar trees near its larvae's root tunnels.
beetle
Regal Moth (Hickory Horned Devil)
One of the largest moths in North America, with orange-red and gray-veined wings on the adult, best known for its enormous, formidable-looking caterpillar, the hickory horned devil, a blue-green giant bristling with long orange spines.
mothPredatory 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.
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-bugRootworm
Working unseen below ground, rootworm larvae chew tunnels through the root systems of corn and other crops, the underground counterpart to the small, often striped or spotted beetles seen on leaves and flowers above.
beetle
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.

Crab Spider
Perched motionless atop a flower petal, often perfectly matched to its color, the crab spider is a patient ambusher that waits for pollinators to land within reach of its outstretched front legs.
spider
Fireflies Larvae Glowworm
The larval form of fireflies, often called glowworms, are flattened, segmented crawlers that glow with a steady greenish light. These little predators hunt slugs, snails, and worms in damp ground.
beetle
Water Measurer
Thin as a splinter and slow-stepping across the surface film, the water measurer creeps along pond edges spearing tiny prey with its needle-like snout.
true-bug
Red-Shouldered Bug
A dark, flattened true bug with a bright red-orange collar across its shoulders, often seen clustering beneath goldenrain trees and other soapberry-family hosts.
