The larval stage of butterflies and moths — voracious eating machines that can consume 27,000 times their birth weight before pupating, with thousands of species ranging from harmless monarchs to dangerous puss caterpillars.
Large, clumsy, nocturnal beetles that blunder noisily into windows and lights on warm summer evenings — the adults are harmless leaf-grazers but the larvae (white C-shaped grubs) live in soil for 3–4 years eating plant roots, damaging lawns and crops; badgers and rooks dig up turf to find them.
The world's greatest jumper relative to body size — the common froghopper can jump 70 cm straight up, accelerating at 400 g, which is greater than the force experienced by a fighter pilot in a dogfight; the larvae are hidden inside "cuckoo spit" — the white froth seen on plant stems each spring.
A jumping insect with powerful hind legs and short antennae, eaten across many human cultures and capable, in certain species, of transforming into devastating swarming locusts.
An eight-legged predatory arachnid (technically not an insect but commonly grouped with them) — over 50,000 species worldwide, with prey-capture techniques ranging from web-building to ambush, jumping, lassoing, and net-casting.
An insect that walks on the surface film of still or slow-moving water using hydrophobic leg hairs that trap air — an iconic example of surface-tension locomotion and a model organism for materials science research.
