Good to know

Six things about the peacock

Eyes

Eyes on the wings

The big eyespots on a peacock butterfly flash open to startle birds, which can mistake them for the eyes of something much bigger.

Sound

A hiss in the dark

Disturbed while hibernating, peacocks rub their wings together to make a hissing click that's been shown to scare off mice.

Food

Nettle beginnings

The caterpillars are black and spiky and feed together on stinging nettles, which is a good reason to leave a wild corner in the garden.

Winter

Early riser

Adults sleep through winter in sheds, hollow trees and lofts, which is why peacocks are one of the first butterflies you see in spring.

Taste

Tasting with their feet

Butterflies have taste sensors on their feet, so landing on a leaf tells them straight away whether it is the right plant.

Sun

Solar powered

Butterflies can't fly when they're cold. You'll often see them resting with their wings spread open, soaking up the sun.

The real thing

How to spot one

Check buddleia, sedum and ivy on sunny days in late summer. In early spring, look for ones basking on bare ground after waking from hibernation.

Lend a hand

How to help

Leave a patch of nettles in full sun for its caterpillars. Take care in sheds in winter, as they hibernate there with their wings closed.
