Winter Moth

A small tan-brown moth unusual for flying in the cold of late autumn and early winter, with strongly dimorphic sexes: fully winged males and flightless, near-wingless females that climb tree trunks to lay eggs.

moth
Greenhead Fly

A stout, strikingly green-eyed horse fly that emerges from Atlantic salt marshes in midsummer swarms, where the females bite to feed on blood.

fly
Acorn Weevil

Acorn Weevil

A small brown weevil with an extraordinarily long, thread-thin snout, often longer than its own body, which it uses to drill into developing acorns before laying its eggs inside.

beetle
Vapourer 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
Spotted Wing Drosophila

Spotted Wing Drosophila

A tiny reddish-brown fruit fly, each male marked with a single dark spot near the wingtip, notable for laying eggs in ripening rather than overripe fruit.

fly
Braconid Wasp

Braconid Wasp

A tiny, often overlooked parasitoid wasp best known for laying eggs inside caterpillars and other insect hosts, sometimes leaving telltale clusters of small white cocoons on a host's back.

wasp
Bluet Damselfly

Bluet Damselfly

Small and delicate, bluet damselflies flash brilliant blue and black along the vegetated edges of ponds and lakes, forming mating pairs that fly in tandem while laying eggs directly into plant stems underwater.

dragonfly

Named for the silken nursery tent females weave to guard their hatching young, this slender, long-legged spider carries her large egg sac beneath her body in her fangs until the eggs are ready to hatch.

spider
Wolf Spider

A robust, hairy, ground-dwelling spider with excellent night vision and a habit of chasing down prey rather than trapping it in a web; females are often seen carrying an egg sac or a back full of spiderlings.

spider
Fig Wasp

Fig Wasp

A pinhead-sized wasp that spends nearly its entire life inside a fig, forming one of the most tightly co-evolved partnerships in nature as it pollinates the tree in exchange for a place to lay its eggs.

wasp
Ichneumon Wasp

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
Western Honey Bee

Western Honey Bee

The familiar golden-brown, fuzzy-banded honey bee kept worldwide for honey production and crop pollination, living in large perennial colonies built around wax comb and a single egg-laying queen.

bee
Cuckoo Bee

Cuckoo Bee

A slender, wasp-like bee that lacks pollen-carrying hairs because it never gathers its own pollen, instead sneaking into the nests of other solitary bees to lay eggs that hatch and consume the host's food stores.

bee
Warble Fly

Warble 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
Eastern Pondhawk

Eastern Pondhawk

A bold, ground-perching dragonfly whose bright green females and powdery blue males look almost like different species, and which readily preys on other dragonflies.

dragonfly
Eastern Forktail

Eastern Forktail

One of the smallest and most adaptable damselflies in eastern North America, the Eastern Forktail thrives in everything from wild marshes to roadside ditches, with bright green-and-black males and color-changing females.

Birdwing Butterfly

Birdwing Butterfly

Among the largest butterflies on Earth, birdwings soar through rainforest canopies on angular, bird-like wings. Males dazzle with iridescent greens, golds, and blues, while the larger females wear more subdued browns.

butterfly
Glowworm Beetle

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.
