Squash Vine Borer

Squash Vine Borer

A day-flying, wasp-mimicking moth whose orange fuzzy hind legs and metallic wings make it easy to mistake for a wasp as it darts around squash vines.

moth
Trichogramma Wasp

Trichogramma Wasp

Barely larger than a speck of dust, the trichogramma wasp is one of the tiniest insects known. These minute parasitoids lay their eggs inside the eggs of moths and butterflies.

wasp
Whitefly

Whitefly

A tiny, moth-like white insect that clusters on the undersides of leaves and bursts into a snowy cloud when the plant is disturbed. Despite the name, it is not a true fly but a sap-feeding relative of aphids and scale insects.

Antheraea Silkmoth

Antheraea Silkmoth

A large, robust silkmoth in the genus Antheraea with broad reddish-brown to tan wings, each marked with a prominent transparent, eye-like spot, representing a group of giant moths long valued for producing wild silk.

moth
Asian Tiger Mosquito

Asian Tiger Mosquito

A small, dark mosquito boldly marked with silvery-white stripes, including one distinctive stripe running straight down the center of its back, that bites readily in broad daylight.

fly

Louse 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.

Dead Leaf Mantis

Dead Leaf Mantis

A master of disguise whose broad, curled, vein-textured body is nearly indistinguishable from a curled, decaying leaf lying on the forest floor.

mantis-stick
Javanese Leaf Insect

Javanese Leaf Insect

A broad, veined, leaf-green body makes this insect nearly indistinguishable from the foliage it feeds on, a masterclass in disguise native to the forests of Southeast Asia.

mantis-stick
Red Wood Ant

Red Wood Ant

A large woodland ant with a reddish-brown thorax and dark abdomen, famous for building towering dome-shaped mounds of pine needles and twigs in forest clearings.

ant

Brown Lacewing

Smaller and less conspicuous than its green relatives, the Brown Lacewing is a subtle but effective predator of aphids and other tiny insects in gardens, forests, and orchards.

other

Soil Mite

A microscopic, heavily armored mite found by the millions in a single handful of soil, quietly breaking down leaf litter and helping build the fertile ground beneath forests and fields.

arachnid

Fireflies (Lightning Bug)

A soft-bodied beetle that turns summer evenings magical by flashing rhythmic patterns of cold light from its abdomen to attract mates across meadows and forest edges.

beetle
Northern Pearly-eye

Northern Pearly-eye

A shade-loving brown woodland butterfly with rows of dark, pale-ringed eyespots, more often seen resting on tree trunks in forest gaps than flying in open sun.

butterfly

Army Ant

A nomadic predator that never builds a permanent nest, instead forming temporary living bivouacs from its own linked bodies and sweeping through the forest floor in massive predatory raids.

ant
Western Conifer Seed Bug

Western Conifer Seed Bug

A large brown true bug with flattened, leaf-shaped hind legs, native to conifer forests of the western United States but now widespread and notorious for gathering on and inside buildings as cooler weather approaches.

true-bug
Ebony Jewelwing Damselfly

Ebony Jewelwing Damselfly

With a metallic emerald body and wings of solid inky black, the ebony jewelwing flutters like a delicate butterfly along shaded forest streams rather than darting like most other damselflies.

dragonfly
West Virginia White

West Virginia White

A delicate, pure-white spring butterfly of eastern hardwood forests with faint gray veining on the underside, flying only for a few weeks each year before its short-lived toothwort host plants fade.

butterfly
Wolf Spiderling

Wolf Spiderling

A tiny, fast-moving juvenile wolf spider, often seen riding in dozens on its mother's back before dispersing to hunt on its own across open ground.

spider
Golden Silk Orb Weaver

Golden Silk Orb Weaver

Suspended in a massive, glinting web strung between trees along a forest trail, the golden silk orb weaver is one of the largest and most striking web-building spiders in the Americas, spinning silk with a distinctive yellow-gold sheen.

spider
Harvestman

Harvestman

An arachnid built almost entirely of legs, with a single compact, oval body segment and no waist separating it into two parts like a true spider. Common in gardens and forests worldwide, it scuttles along on impossibly long, thin legs scavenging for food after dark.

arachnid
Human Bot Fly

Human Bot Fly

A stout, dark-bodied fly from the American tropics famous for an unusual reproductive trick: it captures a blood-feeding mosquito mid-flight and glues its own eggs to the mosquito's body before releasing it to carry them to a future host. The adult itself is rarely seen, spending most of its short life in shaded forest understory.

fly
Dragonfly Nymph

Dragonfly Nymph

A stocky, camouflaged underwater predator that spends months or years stalking prey along the pond bottom before transforming into an aerial dragonfly.

aquatic-insect

Mayfly Nymph

A short-lived aquatic grazer with feathery gills along its abdomen, living for months underwater before a brief, spectacular mass emergence as a winged adult.

aquatic-insect
Zebra Longwing

Zebra Longwing

A slow-flying, long-winged black butterfly striped boldly with yellow, unusual among butterflies for feeding on pollen as an adult, which extends its lifespan to several months.
