Insects: Bees, Beetles, Butterflies & Ants

Insects dominate animal diversity on land. Three body parts, six legs and usually wings separate them from spiders and crustaceans at a glance. Confusion pairs that drive search traffic — bee versus wasp, butterfly versus moth, ant versus termite — belong on a type page, not buried in a single species FAQ.

Beetles are the largest insect order by described species. Bees and many flies are major pollinators of wild and crop plants. Habitat loss, pesticides and light pollution drive declines in many monitored groups. Stick insects and mantises illustrate camouflage and ambush respectively. When insect biomass falls, birds, bats and crops feel it next. Use this page for the six-leg rules, then open the species and family guides for status. WARN insect guides linked from this page cover bees, butterflies, moths, beetles, ants, dragonflies, mantises, stick insects and familiar household species. Gardeners deciding whether to kill a bee-like insect should check hairiness, waist shape and nest type before assuming every striped flyer is a wasp.

How to recognise them

The features that separate this group in the field, in the order they are usually most useful.

Six legs, three parts

Head, thorax and abdomen with six legs. Spiders have eight legs and two main body regions.

Wings

Most adult insects have one or two pairs of wings; beetles hide the flight wings under hardened elytra.

Bee versus wasp

Bees are usually hairier and more robust; many wasps are smoother with a sharper waist. Both can sting; behaviour and nest type differ.

Butterfly versus moth

Butterflies typically rest with wings closed and have clubbed antennae; many moths rest wings open and have feathery antennae — with exceptions.

The confusion pairs

Ladybird versus other beetles: dome and elytra spots. Dragonfly versus damselfly: dragonflies rest with wings open; damselflies usually fold them.
