Tiny beetles that bore beneath tree bark to lay eggs in galleries — under normal conditions they kill only weakened trees, but when populations explode during drought or after storm damage, they can kill millions of healthy trees across entire forests; the European spruce bark beetle has killed more trees than any other insect in European history.
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.
A large, fuzzy, surprisingly cold-tolerant social bee that pollinates many crops honeybees can't reach — beloved by gardeners, declining alarmingly across multiple species.
A brilliantly coloured day-flying moth of chalk downland and coastal grassland — the six-spot burnet has six vivid red spots on metallic blue-black forewings, a warning colouration that advertises its toxicity; burnet moths produce hydrogen cyanide from their own tissues as a chemical defence, making them poisonous to predators; conspicuous in sunshine on downland flowers, flying weakly but apparently without concern for predators.
A large orange-and-black butterfly famous for an annual multi-generation migration of up to 4,800 km between Canada and central Mexico.
An aquatic insect whose larvae build elaborate protective cases from pebbles, sand, twigs, or leaf fragments cemented with silk — a key indicator of clean water quality and the inspiration for fly-fishing artificial lures.
A fast-moving multi-legged predatory arthropod (technically not an insect but commonly grouped with them) — its venomous front "fangs" make it one of the few terrestrial invertebrates capable of delivering a painful bite to humans.
A loud-singing insect spending 13 or 17 years underground as a nymph before emerging in massive synchronized broods to mate and die within weeks.
Moths with transparent wings that convincingly mimic wasps and bees — the hornet moth looks exactly like a hornet; other species mimic bumblebees or wasps so precisely that even experienced naturalists hesitate; adults are active by day and fly fast; larvae bore in tree trunks, stems, and roots for 2–3 years.
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.
A slender relative of the dragonfly that holds its wings folded together over its back at rest — graceful aerial hunters of stream and pond edges, distinguishable from dragonflies by their delicate build.
A large, prehistoric-looking aquatic insect with enormous sickle-shaped jaws (in males) whose larvae spend up to three years in clean streams before emerging for a brief, non-feeding adult life of 3–7 days.
A large, fast-flying dragonfly that migrates thousands of kilometers across North America in a multi-generational journey, an ancient predator with extraordinary aerial agility.
An insect that feeds, reproduces, and navigates by animal dung — it rolls dung balls away from the pile, buries them, and lays eggs inside; the ancient Egyptians considered the scarab dung beetle sacred and a symbol of resurrection.
A bioluminescent beetle whose flashing courtship signals light up summer evenings, with each species using a distinctive flash pattern to find mates.
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.
Britain's only green butterfly — the vivid emerald underside of its wings makes it one of the most beautiful small butterflies of spring; the upperwing is a dull brown, making it effectively invisible when perched on brown vegetation, but when it opens its wings momentarily in sunlight the green underside flashes brilliantly; associated with gorse, broom, and bilberry on heathland and downland.
A large, fast-moving, predatory beetle that hunts at night — one of the gardener's best allies, consuming slugs, aphids, and other pests by the thousand, and a key component of healthy soil ecosystems.
A flying social insect that pollinates roughly a third of human food crops and produces honey from the nectar of flowers.
A large biting fly with painful blood-feeding females — capable of cutting through skin with scissor-like mouthparts, leaving wounds that bleed freely and persist for hours, with major impacts on livestock and outdoor activities.
The master mimics of the insect world — hoverflies are entirely harmless flies that mimic the yellow-and-black warning patterns of bees and wasps with remarkable accuracy; they hover motionless mid-air and visit flowers as important pollinators; the larvae include important aphid predators and the bizarre "rat-tailed maggot" that breathes through a snorkel tube while living in polluted water.
A common name for several stout-bodied scarab beetles that emerge in early summer in North America, the bumbling, light-attracted nighttime fliers familiar to anyone with a porch light.
A green, leaf-mimicking long-horned insect closely related to crickets and grasshoppers, with an iconic raspy "katy-did, katy-didn't" night call from male wing-rubbing.
A delicate green or brown insect with large, elaborately veined transparent wings and golden eyes — whose larvae are ferocious aphid hunters earning them the nickname "aphid lion," making lacewings one of the most beneficial insects in gardens and agriculture.
A small, dome-shaped beetle in red, orange, or yellow with black spots — beloved by gardeners as a voracious aphid predator and a symbol of good luck across cultures.
A multi-legged arthropod with two pairs of legs per body segment (unlike centipedes' one) — slow-moving detritivores essential to forest decomposition, with some giant African species reaching nearly 40 cm long.
A small, blood-feeding fly responsible for more human deaths annually than any other animal, the primary vector for malaria, dengue, yellow fever, and Zika.
A tiny biting midge so small it slips through standard window screens, leaving disproportionately painful itchy welts — the bane of summer evenings in coastal and wetland areas.
A strange, flightless beetle with a swollen, soft abdomen and a fascinating life history — females lay thousands of eggs, the tiny larvae (triungulins) climb flowers and hitch a ride on mining bees back to their burrows, where they feed on the bee's pollen stores and develop through multiple larval stages; when threatened, the beetles exude a blistering oil (cantharidin) from their leg joints.
The most economically damaging forest pest in Europe — the large pine weevil is a dark, mottled brown weevil whose adults feed on the bark of young conifer trees, girdling and killing transplanted seedlings; it is the primary threat to commercial conifer replanting across Scandinavia and northern Europe, where it can destroy entire newly planted coupes; adults feed at night, concealing themselves under bark and debris by day.
The single reproductive female of a honey bee colony, mother to all 50,000+ workers, possessing distinctive elongated body, a smoother stinger she uses repeatedly, and a lifespan many times longer than worker bees.
The apex predators of the insect world — powerfully built flies that hunt other insects on the wing, seizing prey mid-air with spiny legs and injecting a paralysing venom, then sucking the prey dry; they tackle prey larger than themselves including wasps, bees, and dragonflies.
A large family of beetles with characteristically short wing covers that expose most of the abdomen — the most species-rich beetle family, playing crucial roles as predators, scavengers, and even ant-colony infiltrators.
An ancient arachnid with venomous tail and pincered front claws — among the oldest land animals on Earth (430 million years), with surprising longevity and bizarre fluorescence under UV light.
A small, primitive, wingless insect with a silver-gray scaly body and a long-evolutionary lineage, found in damp homes feeding on starches, paper, and book bindings.
Britain's largest insect — the male stag beetle's enormous antler-like jaws can be longer than his body but are used for wrestling rival males rather than biting; a declining species dependent on rotting wood in old gardens and ancient parkland; adults do not feed and live only a few weeks as adults after 3–7 years as grubs.
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.
An ancient aquatic insect whose larvae are the gold standard of clean water — stonefly larvae require highly oxygenated, cold, unpolluted streams to survive, making them invaluable biological indicators of water quality; adults are drab, flat-winged insects that rest on bankside stones and vegetation, rarely flying far from the stream where they developed; one of the most ancient insect orders, with fossils over 300 million years old.
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.
A wingless wasp despite the name "ant," covered in dense bright fur, with a famously painful sting earning the nickname "cow killer" — the female only; males have wings and don't sting.
The most damaging garden pest in Britain — its soil-dwelling larvae eat through the roots of container plants and garden favourites including fuchsia, begonia, heuchera, and strawberry, causing sudden plant collapse; the adult is a dull black beetle that notches leaf edges at night and cannot fly.
A tiny sap-sucking insect pest that colonizes the undersides of leaves, weakening plants and transmitting viruses — a major problem in greenhouse agriculture and tropical food crops worldwide.
A small blue butterfly of California's San Francisco peninsula — extinct since the 1940s, the first North American butterfly species lost to habitat destruction, and the namesake of the Xerces Society for invertebrate conservation.
A small white moth bound to yucca plants in an obligate mutualism — the only insect that pollinates yucca, while yucca seeds are the only food its larvae can eat.
