Furniture Beetle
A tiny, reddish-brown to dark brown cylindrical beetle whose larvae, commonly called 'woodworm,' bore small round tunnels through seasoned furniture and timber.
beetle
Longhorn Beetle
A beetle instantly recognizable by antennae often longer than its own body, ranging from small woodland species to large, dramatically patterned tropical and temperate forms.
beetle
Ground Beetle
A fast-moving, shiny black or metallic beetle with long legs and prominent jaws, usually found scurrying under rocks and debris where it hunts other small invertebrates.
beetleBurying Beetle
A black beetle marked with bold orange-red bands, notable for locating small dead animals, burying them underground, and cooperatively raising larvae with a partner over the buried carcass.
beetleGlowworm 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
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
Long-Legged Fly
A jewel-bright little fly that flashes metallic green, blue, or bronze in the sunlight as it darts across leaves on comically long, stilt-like legs, pausing to perform quick territorial displays. Both adults and larvae are active hunters of even smaller insects, making this tiny fly a useful predator in gardens and wetlands alike.
fly
American Carrion Beetle
A broad, flattened black beetle with a striking pale yellow shield behind its head, commonly found on and around small animal carcasses where it feeds alongside fly larvae.
beetle
Striped Cucumber Beetle
A small, bright yellow beetle marked with three bold black stripes running the length of its wing covers, a frequent and highly visible visitor to cucumber, squash, and melon plants.
beetle
Spotted Cucumber Beetle
A small, elongated yellow-green beetle marked with twelve black spots across its wing covers, commonly seen on cucurbit and corn plants throughout the growing season.
beetleWater Penny Beetle
A flattened, coin-shaped larva that clings almost invisibly to the surface of submerged stream rocks, named for its uncanny resemblance to a small penny.
aquatic-insectGnat
A catch-all common name for a wide range of tiny, delicate flies, some no bigger than a grain of pepper, often seen hovering in small clouds near water, moist soil, or overripe produce.
fly
Flesh Fly
A bristly gray fly marked with three dark thoracic stripes and a checkerboard-patterned abdomen, often spotted hovering near carrion or garbage.
fly
Crane Fly
A long-legged, mosquito-like fly with a slender tan or gray body and a single pair of narrow wings, often seen wobbling clumsily around outdoor lights on summer evenings.
flyLouse Fly
A flattened, leathery-bodied fly that clamps onto fur or feathers with stout claws and scuttles sideways like a tiny crab rather than taking flight when disturbed. Several species shed their wings for good once they settle on a permanent host, spending the rest of their lives buried in fleece or plumage.
flyMarsh Fly
A slender, unassuming fly best known for larvae with a remarkable diet: nearly every species in the family feeds on aquatic or terrestrial snails and slugs, making marsh flies natural specialists in wetland food webs. Adults are often found resting quietly on sedges and other marsh vegetation near the water's edge.
fly
Ladybug
A small, round, brightly colored beetle with a domed, shiny shell typically red or orange with black spots, one of the most recognizable and beloved beetles found in gardens worldwide.
beetleTsetse 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.
flySoldier Fly
A wasp-mimicking fly with a flattened, often metallic body that spends its larval life quietly breaking down decaying plant matter or aquatic debris.
flyPhorid Fly
A tiny, hump-backed fly best known for scuttling erratically across countertops and floors rather than taking flight, drawn to anything rotting or moist.
fly
Fig Beetle
A large, dull metallic-green scarab beetle with a loud, buzzing flight, often seen crash-landing near ripe or overripe fruit and compost piles on warm summer days.
beetleWarble Fly
A furry, bee-mimicking fly that never lands on flowers or feeds as an adult, spending its brief life darting around grazing cattle to lay eggs on their legs and lower body. Herds sometimes react with sudden panicked runs, known as gadding, whenever a warble fly approaches.
fly
Jewel Beetle
A sleek, bullet-shaped beetle wrapped in brilliant iridescent metallic colors — green, copper, blue, or gold — that seem to shift with the angle of light.
beetleDung Beetle
A stout, often glossy black or metallic beetle famous for rolling, burying, or tunneling into animal dung, an unglamorous but ecologically vital habit that recycles nutrients back into the soil.
