A small, bright orange-and-black butterfly with fiery copper-colored forewings and dusky gray hindwings edged in orange, commonly seen darting low over weedy fields and vacant lots.
butterfly
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.
flyFire Ant Queen
The reproductive powerhouse of a fire ant colony, noticeably larger than the reddish worker ants and equipped with wings before she sheds them to found a new nest.
ant
Gray Hairstreak
A small slate-gray butterfly with thin white lines, an orange-capped black spot near the hindwing tail, and one of the broadest host-plant ranges of any North American butterfly, making it a familiar visitor to gardens and fields alike.
butterfly
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
Eastern Comma
A ragged-edged orange-and-brown woodland butterfly named for the small, silvery comma-shaped mark on the underside of its hindwing, with a cryptic dead-leaf pattern that camouflages it perfectly when its wings are closed.
butterflyLonghorn Bee
A fuzzy, medium-sized solitary bee named for the males' notably long, curved antennae, commonly seen foraging on sunflowers, asters, and other late-summer composite flowers.
bee
Daddy Longlegs
A small, oval-bodied arachnid carried on extremely long, thread-like legs, distinct from true spiders in having a one-piece fused body and no silk glands or web.
arachnidTreehopper
A small, oddly shaped sap-feeding bug best known for an enlarged, often bizarre pronotum extending backward over its body, sometimes shaped like a thorn, leaf, or spike.
true-bugOdorous House Ant
A dark, unassuming ant best known for releasing a smell reminiscent of rotten coconut when a worker is crushed.
antBot Fly
A stocky, bumblebee-mimicking fly whose adults never feed and live only long enough to mate and locate a rodent or rabbit burrow for their eggs. Despite their harmless, buzzing adult stage, bot flies are best known through the larvae that develop as internal parasites of small mammals.
fly
European Paper Wasp
A slender, orange-antennaed social wasp that builds small, open umbrella-shaped paper combs under eaves and ledges, now common well beyond its native European range.
wasp
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.
mothKatydid
A leaf-mimicking insect with broad, veined green wings shaped remarkably like foliage, best known for the loud, rhythmic 'katy-did, katy-didn't' chorus males produce on warm summer nights.
grasshopper-cricket
Roseate Skimmer
A vivid pink-violet dragonfly of southern wetlands, the mature male's rose-pruinose body makes it one of the most striking skimmers found around ponds and canals.
dragonfly
Rhinoceros Beetle
A massive, heavily armored beetle whose males sport a single large, curved horn projecting forward from the head, used to shove and flip rival males in contests of strength.
beetle
Non-Biting Midge
A mosquito look-alike that gathers by the thousands in swirling mating swarms near lakes and ponds, despite lacking any ability to bite.
fly
Common Whitetail Dragonfly
A stocky pond-side dragonfly whose mature males sport a broad, chalky white abdomen that flashes conspicuously against boldly banded wings.
dragonflySnipe Fly
A slender, long-legged fly often seen perched head-down on a sunny tree trunk or fence post, patiently watching for smaller insects to ambush. Its tapered, wasp-like abdomen and habit of resting motionless with legs splayed give it a distinctive, almost sentry-like posture in woodland clearings.
fly
Mosquito
A slender, long-legged fly with a needle-like proboscis, narrow wings, and a distinctive high-pitched wing hum, most active around dawn, dusk, and in shaded, humid areas.
fly
Twenty-plume Moth
A tiny, unusual moth whose wings are each divided into numerous slender, feather-like plumes rather than solid membranes, giving it a delicate, fringed appearance unlike almost any other moth.
mothAnt-mimic Spider
A slender jumping spider that walks on six legs while waving the front pair like antennae, convincingly passing itself off as an ant to fool predators and prey alike.
spider
Gulf Fritillary
A vivid orange, long-winged butterfly whose underside gleams with brilliant metallic silver spangles, closely tied to passionflower vines throughout the warmer parts of the Americas.
butterfly
Twelve-spotted Skimmer
A big, boldly patterned skimmer whose wings each carry three chocolate-brown patches, and whose mature males add chalky white flashes between them for a striking black-and-white flicker in flight.
