wasp
Southern Flannel Moth (Puss Caterpillar Moth)
A small, densely furred tan-to-orange moth best known for its unusual larva, a soft-looking, cat-tailed caterpillar whose fluffy coat hides rows of venomous spines.
moth
Leaf Miner
Rather than chewing from the outside, a leaf miner larva tunnels between the upper and lower surfaces of a leaf, leaving behind pale, winding trails or blotches that trace its path as it feeds.
fly
Codling Moth
A small, inconspicuous grey-brown moth best known through the work of its larva, the classic apple 'worm' that tunnels into fruit, making this tiny moth one of the most economically significant insects in orchards worldwide.
moth
Glowworm 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
Chigger
A nearly microscopic mite larva that waits in clusters on grass tips for a passing host, taking a single brief meal before dropping away unseen. Only this larval stage is parasitic; the free-living adult spends its life hunting tiny prey in the soil.
arachnid
Fox Moth
A stout, reddish-brown moth with a pale diagonal band across each forewing, closely resembling a fox in color, most often noticed as its large, densely furred dark caterpillar basking on open ground in spring.
moth
Lacewing

Regal Moth (Hickory Horned Devil)
One of the largest moths in North America, with orange-red and gray-veined wings on the adult, best known for its enormous, formidable-looking caterpillar, the hickory horned devil, a blue-green giant bristling with long orange spines.
moth
Onion Fly
A slender gray fly closely related to houseflies whose white legless larvae bore into onion bulbs, feeding in clusters within a single rotting bulb.
fly
Carpet Beetle
A tiny, rounded beetle with a mottled scale pattern of white, brown, and yellow, whose bristly larvae are known for feeding on wool, fur, and other dried animal fibers indoors.
beetle
Pink Toe Tarantula
An agile, tree-dwelling tarantula with a dark velvety body and distinctive pale pink tips on its feet, the pink toe spends nearly its entire life above ground, spinning silk retreats among leaves and bark high in the rainforest canopy.
spider
Stag Beetle
A large, glossy beetle whose males wield oversized, antler-like mandibles resembling a stag's rack of horns, used for wrestling rival males rather than for feeding.
beetle
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
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
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
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
Caddisfly
A moth-like insect whose larvae are famous for constructing portable protective cases out of silk and whatever sand, twigs, or debris they can find.
aquatic-insect
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
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
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.
