01 · BigWings like dinner plates

Its wings have a larger area than those of almost any other insect: about the size of a dinner plate.

02 · SnakeA snake on each wing

The tip of each forewing looks like the head of a snake, with an eye and a mouth. When disturbed it shakes them slowly.

03 · MouthIt never eats

The adult has no working mouth. It lives for a week or two on the fat it stored as a caterpillar.

04 · WindowsWindows in its wings

Each wing has a see-through patch with no scales. Nobody knows quite what they are for.

05 · ScentFound by scent

The male's feathery antennae can pick up a female's scent from several kilometres away.

06 · SilkIts silk is used

The cocoon is spun from tough brown silk, which people in India weave into a cloth called fagara.

Good to know

Six things about the Asian rainforest

Old

A very old forest

The forest has stood since the time of the dinosaurs, which has given its insects a long time to become strange.

Tall

The tallest tropical trees

Some trees here pass ninety metres. Most insects live far above your head.

Mimic

Masters of disguise

Mantises that look like orchids, moths with snake heads on their wings, and insects shaped like leaves all live here.

Salt

Butterflies at puddles

Male butterflies gather in crowds on wet sand and mud to drink the salts they need.

Ants

Ants as farm workers

For well over a thousand years, fruit growers in Asia have put weaver ant nests in their trees to kill pests.

Loss

A shrinking forest

Much of the lowland forest has been cleared for timber and oil palm. Many of its insects live nowhere else.

The oldest forest of all

Borneo's rainforest is around 130 million years old, older than the Amazon. One tree there can hold more kinds of insect than live in the whole of Britain.
