List of 11-letter Insects

    1

    Assassin Bug

    Reduviidae (family; approximately 6,800 species)

    A predatory true bug that ambushes and stabs other insects with a powerful curved rostrum, injecting saliva that liquefies the victim's tissues — with some species also capable of transmitting Chagas disease to humans.

    2

    Buff-tip Moth

    Phalera bucephala

    One of Britain's most extraordinary camouflaged insects — at rest, the buff-tip moth is almost indistinguishable from a broken birch twig, with its pale yellow-buff wing tips and grey middle aligned to mimic a stub of birch; the hairy, yellow-and-black larvae are gregarious and can strip a tree of leaves in days.

    3

    Caterpillar

    Lepidoptera (order, larval stage)

    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.

    4

    Click Beetle

    Agrypnus murinus

    A beetle that escapes predators by snapping its body to launch itself into the air with an audible click — a remarkable mechanical hinge mechanism that can catapult the beetle up to 30 cm high.

    5

    Emperor Moth

    Saturnia pavonia

    Britain's only day-flying member of the silk moth family — the male emperor moth is one of the most spectacular insects on British heathland, with large owl-like eyespots on all four wings; the male can detect a female's pheromone from up to 11 km away; the caterpillar is a vivid green and black jewel, and the silk cocoon was once harvested.

    6

    Grasshopper

    Schistocerca americana (American grasshopper)

    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.

    7

    Scorpionfly

    Panorpa communis (and related Panorpa species)

    A bizarre-looking woodland insect named for the male's upturned, scorpion-like tail — actually the genitalia, not a sting; scorpionflies have a long, beak-like rostrum, mottled brown and yellow wings, and a peculiar habit of stealing prey from spider webs; they are significant scavengers of dead insects and small animals, and are among the oldest winged insect lineages.

    8

    Stick Insect

    Phasmatodea (order)

    Masters of camouflage that resemble twigs, leaves, or sticks — over 3,000 species worldwide, with some Asian species reaching 60 cm long, including several capable of parthenogenetic reproduction without males.

    9

    Tortrix Moth

    Family Tortricidae (various genera)

    Small, bell-shaped moths whose caterpillars are among the most damaging to gardens and orchards — they roll leaves into shelters bound with silk and eat the enclosed tissue; the codling moth (apple's worst enemy) and the light brown apple moth are tortrix moths, and European vine moth damages grapevines worldwide.

    10

    Water Beetle

    Dytiscus marginalis (great diving beetle) and related Dytiscidae

    Aquatic beetles that have evolved to live in ponds, streams, and lakes — the great diving beetle is Britain's most spectacular aquatic insect, an aggressive predator that will attack fish, frogs, and newts; it carries an air bubble under its wing cases to breathe underwater and can fly between ponds at night.
