Water Scavenger Beetle
Rounded and glossy, water scavenger beetles paddle through weedy ponds gathering air with a short antenna rather than a snorkel-like tube, feeding mostly on decaying plant matter and algae.
beetle
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
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
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
Old Lady Moth
A large, dusky brown noctuid moth with an intricate, wood-grain-like pattern of dark streaks and pale flecks across broad wings, often found resting motionless in sheds and against tree bark by day.
moth
Drywood Termite
A termite that lives entirely within the dry wood it feeds on, needing no soil contact at all, and revealing itself mainly through small piles of pellet-like frass pushed from tiny exit holes.

Golden Tortoise Beetle
A tiny, dome-shaped beetle famous for its brilliant, mirror-like gold sheen, which it can dial down to a dull orange or spotted reddish tone within minutes when disturbed or handled.
beetle
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
Creeping Water Bug
Broad, oval, and flattened like a tiny shield, the creeping water bug crawls methodically through submerged vegetation rather than swimming freely, using its stout, raptorial front legs to seize prey.
true-bug
Devil's Coach Horse Beetle
A large, matte-black rove beetle that raises its flexible abdomen up and over its back like a scorpion's tail and gapes its jaws when threatened, one of the biggest and most dramatic rove beetles in Europe.
beetle
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
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
Vinegaroon
A robust, dark, scorpion-like arachnid whose long, thin whip for a tail gives it its name, and whose signature defense is spraying a concentrated mist of vinegar-scented fluid rather than stinging. Despite its intimidating look, it has no venom at all.
arachnid
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.
fly
Bark Scorpion
A slender, pale tan scorpion best known for its unusual habit of climbing trees, walls, and rock faces rather than staying on the ground like most scorpions. Its thin build and long, narrow tail set it apart from the stockier, heavy-clawed scorpions found elsewhere.
