spider
Blacklegged Tick
A tiny, teardrop-shaped tick with dark legs and a reddish-brown abdomen that lurks in leaf litter along woodland trails.
arachnid

A small mottled moth whose larva builds a tiny portable silk case, dragging its own protective shelter along as it grazes on wool and fur.
moth
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
Webbing Clothes Moth
A small, plain golden-buff moth that avoids light and flutters weakly from dark closets, leaving silken webbing where its larvae have grazed on wool and fur.
moth

beetle
Case-bearing Clothes Moth
A tiny, drab tan moth whose larva constructs and carries a small portable silk case as it feeds on wool, fur, and other keratin-based fibers, making it a recognized fabric pest in homes.
mothSnipe Fly
A slender, long-legged fly often seen perched head-down on a sunny tree trunk or fence post, patiently watching for smaller insects to ambush. Its tapered, wasp-like abdomen and habit of resting motionless with legs splayed give it a distinctive, almost sentry-like posture in woodland clearings.
flyPolyphemus Moth Caterpillar
A plump, apple-green giant silk moth larva with rows of silvery spots that swells to the size of a large finger before spinning a papery brown cocoon.
caterpillar-larva
Mealybug
A soft, oval insect coated in a powdery white waxy secretion that gives it a fuzzy, cotton-like appearance, typically found clustered in leaf joints and along stems of houseplants.
true-bugMosquito Larva
A wriggling, comma-shaped aquatic larva that hangs from the water's surface to breathe before transforming into a flying adult mosquito.
aquatic-insect
Silkworm
Plump, pale, and utterly dependent on humans, the silkworm is the domesticated caterpillar behind thousands of years of silk production, spinning a single continuous thread of silk to form its cocoon.
caterpillar-larvaBraconid 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
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.
