Carpet Beetle
A tiny, rounded beetle with a mottled scale pattern of white, brown, and yellow, whose bristly larvae are known for feeding on wool, fur, and other dried animal fibers indoors.
beetleLily Leaf Beetle
A brilliant scarlet-red beetle with a jet-black head, legs, and underside that feeds almost exclusively on true lilies and fritillaries, often stripping leaves down to bare stems.

Black Soldier Fly
A sleek, dark, wasp-like fly whose larvae are voracious decomposers of decaying organic material, while the short-lived adults do not feed at all.
flyGlowworm 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.
beetle
Bagworm Moth
A moth best known for its larva's habit of constructing and living inside a spindle-shaped case of silk and plant debris that hangs from twigs, with adult males a plain sooty-winged moth and females remaining wingless and grub-like inside the bag for life.
moth
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.
beetleFlea Beetle
A tiny, shiny beetle that springs away like a flea when disturbed, leaving characteristic small round holes peppered across the leaves it feeds on.
beetle
Goliath Beetle
One of the largest and heaviest beetles on Earth, a massive scarab with a bold pattern of black, white, and brown stripes across its shield-like body.
beetle
Hercules Beetle
One of the largest beetles in the world, with males bearing dramatic, forceps-like horns nearly as long as the rest of their armored, olive-green body.
beetle

beetle
Long-Legged Fly
A jewel-bright little fly that flashes metallic green, blue, or bronze in the sunlight as it darts across leaves on comically long, stilt-like legs, pausing to perform quick territorial displays. Both adults and larvae are active hunters of even smaller insects, making this tiny fly a useful predator in gardens and wetlands alike.

Rove Beetle
A slender, fast-running beetle with unusually short wing covers that leave much of its flexible abdomen exposed, often curling its tail upward like a scorpion when alarmed.
beetleWater 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.
beetleGolden 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
Scarab Beetle
A broad, often glossy beetle family recognized by its distinctive fan-like clubbed antennae, ranging from tiny dung-rollers to massive horned giants, found on every continent except Antarctica.
beetle
Tachinid Fly
A bristly, house-fly-like insect that looks unremarkable at a glance but hides one of the most important ecological roles among flies: its larvae develop as internal parasites of caterpillars, beetles, and other insects, quietly regulating populations across the landscape. Gardeners often welcome tachinid flies as natural allies against crop-damaging pests.
