Fire 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
Odorous House Ant
A dark, unassuming ant best known for releasing a smell reminiscent of rotten coconut when a worker is crushed.
ant
Antlion
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.
other
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
Broad-Headed Bug
A slender, dark true bug with a notably wide head, whose nymphs are remarkable ant mimics that scurry among leaf litter before maturing into fliers that resemble small leaf-footed bugs.
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-bug
Orange Tip
A dainty white butterfly whose males flash vivid orange wingtip patches, while both sexes show a beautifully marbled green-and-white pattern on the underwings.
butterfly
Falcate Orangetip
An early-spring white butterfly whose males flash bright orange wingtips, while both sexes show a distinctive hooked (falcate) forewing shape and marbled green underside pattern.
butterfly
Digger Bee
A robust, fast-flying, densely furry solitary bee that excavates tunnels in bare or sloped soil, often confused with bumble bees due to its bulky, hairy build and loud buzzing flight.
bee
Vaporer Moth
A tussock moth with dramatic sexual differences: the male is a small rusty-brown day-flying moth with a white wing spot, while the female is a flightless, wingless gray sac-like insect that never leaves her cocoon.
moth
Vapourer Moth
A small tussock moth with striking sexual dimorphism: rusty-orange, day-flying males with feathery antennae contrast with flightless, grub-like grey females that never leave their cocoon to lay eggs.
moth
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
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
Moth
A broad group of scale-winged insects related to butterflies, typically nocturnal, with stout, often furry bodies and feathery or thread-like antennae.
moth
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
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
Midge
A slender, mosquito-like fly that forms dense swarms near water at dusk, easily mistaken for a mosquito but lacking any biting mouthparts.
fly
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
Giant Asian Mantis
A bulky, leaf-green predator that sits patiently among foliage, its powerful spined forelegs poised to snatch any insect that strays too close.
mantis-stick
Cloudless Sulphur
A large, bright lemon-yellow butterfly that flies with strong, direct wingbeats and rarely shows any dark markings, giving it an almost uniformly 'cloudless' appearance.
butterfly
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.
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
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
Screech Beetle
This small, oval water beetle earns its name from the loud squeak it produces when picked up, a sound made by rubbing internal body parts together rather than by any vocal organ.
