Good to know

Six things about the millipede

Legs

Not a thousand legs

It has about a hundred. Until 2021, no millipede had been found with a thousand.

Wave

Legs that move in waves

The legs lift and fall in ripples that run along the body, which gives it pushing power.

Coil

It coils like a spring

When disturbed it curls into a flat spiral, with its soft legs tucked inside.

Jump

It can flick away

This kind can also thrash and flick itself about to escape.

Food

It eats dead leaves

It chews rotting leaves and wood, and helps to turn them into soil.

Climb

A night climber

After dark it climbs walls and tree trunks to graze on algae and moss.

How to spot one

Look under loose bark and in the leaf litter. On a damp night, shine a torch up a garden wall. Take an adult with you.

Lend a hand

How to help

A layer of dead leaves under shrubs is food and shelter. There is no need to clear it.
