Bug Encyclopedia
Search and identify bugs & insects — beetles, butterflies, moths, ants, bees, spiders and more — with size, habitat, danger, behavior, and how to tell them apart.
Flea
A tiny, wingless, laterally flattened insect built for moving swiftly through fur, famous for its powerful hind legs that allow it to leap many times its own body length.
other
Wool Carder Bee
A stocky, yellow-and-black solitary bee named for its habit of scraping soft plant fibers from fuzzy leaves to line its nest, with territorial males that aggressively patrol and defend flower patches.
bee
Huntsman Spider
With legs splayed crab-like to either side of a flattened body, the huntsman spider is built for speed, capable of scuttling sideways across walls and tree trunks in pursuit of prey.
spider
Marbled Orbweaver
A round-bodied orb weaver with a swollen, marbled orange-and-purple abdomen that builds large, symmetrical webs in damp woodland edges.
spider
Death Watch Beetle
A mottled brown wood-boring beetle famous for the faint ticking sound it taps out inside old timbers, once thought by superstitious listeners to be an omen of death.
beetle
Dampwood Termite
A relatively large termite that nests directly inside heavily moistened, decaying wood such as rotting logs and stumps, needing no soil contact but requiring consistently damp timber.
other
Carpenter Ant
A large, often shiny black ant that excavates smooth tunnels in dead or damp wood for nesting, recognizable by its size, evenly rounded thorax, and elbowed antennae.
ant
Eastern Subterranean Termite
A pale, soft-bodied social insect that lives in vast underground colonies and builds mud tubes to reach and feed on wood cellulose, including structural timber.
other
Bumblebee Carpenter Bee
A large, robust bee that closely resembles a bumblebee at a glance but has a smooth, shiny, hairless abdomen and a habit of boring round nesting tunnels into bare wood.
bee
Termite Swarmer
A dense, short-lived cloud of dark, equal-winged insects pouring from a crack in soil or wood, each one a would-be founder of a brand-new termite colony.
other
Old House Borer
A grayish-brown to nearly black longhorn beetle whose larvae bore extensively through structural softwood, capable of causing large galleries hidden beneath the wood surface.
beetle
Pine Sawyer Beetle
A large, long-antennaed longhorn beetle of pine and spruce forests, mottled gray-brown to black, that produces a rasping sound when handled and whose larvae tunnel deep into dead or dying conifer wood.
beetle
Old Lady Moth
A large, dusky brown noctuid moth with an intricate, wood-grain-like pattern of dark streaks and pale flecks across broad wings, often found resting motionless in sheds and against tree bark by day.
moth
Termite
A pale, soft-bodied social insect that lives in hidden colonies and feeds on cellulose in wood and plant debris, often mistaken for an ant despite belonging to an entirely different insect order.
other
Buff-tip Moth
A moth so convincingly disguised as a broken birch twig that it is often overlooked entirely, with silvery-gray wings and pale buff patches at the tip and base that complete the illusion of snapped, weathered wood.
moth
Ironclad Beetle
A slow-moving, mottled gray beetle famed for having one of the hardest, most crush-resistant exoskeletons of any insect, often found clinging motionless to dead wood or tree bark.
beetle
Drywood Termite
A termite that lives entirely within the dry wood it feeds on, needing no soil contact at all, and revealing itself mainly through small piles of pellet-like frass pushed from tiny exit holes.
other
Ichneumon Wasp
A slender, long-antennaed parasitoid wasp, often mistaken for a giant mosquito or a stinging insect, that is best known for the extraordinarily long ovipositor some species use to drill into wood and lay eggs on hidden larvae.
wasp
Asian Longhorned Beetle
A large, glossy black longhorn beetle patterned with irregular white spots and boldly banded blue-white antennae, notable as one of the largest and most eye-catching wood-boring beetles seen in temperate hardwood trees.
beetle
Meadow Katydid
Small, slender, and beautifully camouflaged among grass blades, meadow katydids fill open fields and marsh edges with a soft, buzzy, insect-like ticking that blends into the summer evening background.
grasshopper-cricket
Clothes Moth
A tiny, pale golden moth that avoids light and flutters weakly from dark closets, more often noticed by the damage its larvae leave in stored fabrics than by the moth itself.
moth
Tsetse Fly
A stout grayish-brown fly of African woodlands whose rigid, forward-jutting proboscis and scissor-folded wings set it apart from any ordinary house fly.
fly
Great Spangled Fritillary
A large, robust orange butterfly with bold black markings above and a striking array of large silvery spangles on a tawny-brown underside, closely tied to woodland violets.
butterfly
Banded Hairstreak
A gray-brown, tailed hairstreak marked by a postmedian band of white-edged dark spots on the hindwing underside and a small orange-capped blue spot near the tail, closely tied to oak and hickory woodlands.
