A gray fly that looks almost identical to the common house fly, but carries a rigid, forward-pointing proboscis built for piercing skin rather than sponging up liquids.

fly
Follicle Mite

Follicle Mite

An elongated, microscopic mite shaped almost like a tiny worm, living deep within hair follicles and oil glands of mammal skin where it spends its entire life largely unnoticed.

arachnid
Crane Fly Larva

Crane Fly Larva

Thick-skinned and worm-like, the crane fly larva, often called a leatherjacket, burrows through wet mud and decaying vegetation at the edges of ponds and streams, breaking down plant material as it grows.

Horse Fly Larva

Horse Fly Larva

Hidden in the wet mud along pond and stream margins, the horse fly larva is a tapered, tough-skinned predator that hunts other small soil and mud-dwelling invertebrates before eventually transforming into the familiar biting fly.

aquatic-insect
Scabies Mite

Scabies Mite

A microscopic, eyeless mite that spends its entire life cycle burrowed within the outer layer of a mammal's skin, among the smallest arachnids known to science. Unlike free-living mites, it has no independent existence away from a host and is studied primarily through microscopic examination rather than direct observation.

arachnid
Fox Moth

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
Rose Chafer

Rose Chafer

A slender, tan, long-legged scarab beetle that gathers in swarms on rose blossoms and other flowers in late spring, chewing petals and foliage into a lacy, skeletonized pattern.

beetle
Hummingbird Hawk-Moth

Hummingbird Hawk-Moth

A day-flying moth that hovers in front of flowers on blurring wings while unspooling a long proboscis to sip nectar, so closely mimicking a hummingbird in flight that it is frequently mistaken for one.

moth
Hummingbird Moth

Hummingbird Moth

Hovering at flowers with a blur of wings and a long uncoiling tongue, the hummingbird moth is easily mistaken for a tiny hummingbird. These plump, fast-flying hawk moths feed on nectar in broad daylight.

moth
Pond Skater

Pond Skater

Skimming effortlessly across the surface of still water on long, spindly legs, the pond skater uses ripples to detect struggling insects, which it seizes and pierces with needle-like mouthparts.

true-bug
Skipper Butterfly

Skipper Butterfly

A stocky, fast-darting butterfly with a large head, hooked antennae tips, and thick furry body, intermediate in appearance between butterflies and moths, named for its quick, skipping flight.
