Search and identify bugs & insects — beetles, butterflies, moths, ants, bees, spiders and more — with size, habitat, danger, behavior, and how to tell them apart.
Puss Moth
A stout, furry gray-and-white moth named for its dense, cat-like coat of hair, best known for its bizarre green caterpillar with a hump-backed, face-like front end and forked tail filaments used in defensive displays.
moth
Giant Leopard Moth
A striking white moth patterned with bold, hollow black rings and dots resembling leopard spots, revealing an iridescent blue-black abdomen marked with orange when its wings part, making it one of the most eye-catching tiger moths in North America.
moth
Lone Star Tick
Named for the single silvery-white spot on the back of the adult female, the lone star tick is unusually active for a tick, moving toward hosts rather than simply waiting for them to pass. Its reddish-brown, ornamented body makes it one of the easier North American ticks to identify at a glance.
arachnid
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.
true-bug
Praying Mantis
An elongated, ambush-hunting insect instantly recognizable by its triangular head, bulging compound eyes, and spiked raptorial forelegs held folded as if in prayer while it waits motionless for prey.
mantis-stick
Bee Fly
A fuzzy, bee-mimicking fly with a long, forward-pointing proboscis that hovers motionless in front of spring flowers while sipping nectar.
fly
Anopheles Mosquito
A slim, mottled-winged mosquito best known for the distinctive head-down, tail-up posture it strikes while resting on walls and vegetation.
fly
Common House Mosquito
A slender, drab brown mosquito that emerges at dusk from catch basins and forgotten containers to fill neighborhoods with its familiar high-pitched whine.
fly
Black Vine Weevil
A flightless, all-black snout beetle notorious for notching the edges of leaves at night while its underground larvae feed on plant roots and crowns.
beetle
Harvester Ant
A large, industrious desert ant that clears a bare, sunburned disk of ground around its nest entrance while collecting and storing seeds by the thousands.
ant
Dance Fly
A slender, long-legged predatory fly named for the swarming courtship dances males perform at dusk, often while carrying a captured insect as an offering.
fly
Common Blue
A small, sun-loving butterfly whose males flash brilliant violet-blue wings while females wear warm brown with a scattering of orange spots.
butterfly
Black Soldier Fly
A sleek, dark, wasp-like fly whose larvae are voracious decomposers of decaying organic material, while the short-lived adults do not feed at all.
fly
Painted Lady Caterpillar
A spiky, mottled caterpillar that spins loose silk webbing over thistle or mallow leaves and hides inside its own protective tent while feeding.
caterpillar-larva
Diana Fritillary
A large southern Appalachian fritillary famous for extreme sexual dimorphism — males are burnt-orange and black while females are an iridescent blue-black that mimics a distasteful swallowtail.
butterfly
Leaf Insect
A living illusion, this flattened green insect reproduces the veins, edges, and even blemishes of a real leaf so precisely that it can vanish while resting in plain sight.
mantis-stick
Deer Fly
A small but aggressive fly with strikingly patterned, dark-banded wings and bright green or gold eyes, often circling the head and shoulders while hunting for a blood meal.
fly
Cabbage Looper Moth
A drab mottled-brown moth best known for its pale green, looping caterpillar that arches its back like an inchworm while feeding on garden vegetables.
moth
Book Scorpion
A tiny, flattened arachnid that looks like a scorpion in miniature, minus the tail, scuttling sideways through old paper and dusty corners while hunting even smaller pests.
arachnid
Ambush Bug
A chunky, irregularly shaped true bug with thickened, raptorial front legs, the ambush bug hides motionless on flowers, blending into the petals while waiting to seize visiting pollinators.
true-bug
Yellow Dung Fly
A golden, densely furred fly whose bright males cluster on fresh cow pats in pastures, competing for mates while ambushing smaller insects drawn to the same spot.
fly
Jerusalem Cricket
A large, wingless, ground-dwelling insect with a shiny amber body, a strikingly human-like face, and a robust, banded abdomen, most often uncovered while digging in soil.
grasshopper-cricket
Hummingbird Hawk-Moth
A day-flying moth that hovers in front of flowers on blurring wings while unspooling a long proboscis to sip nectar, so closely mimicking a hummingbird in flight that it is frequently mistaken for one.
moth
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.
