Peppered Moth

Biston betularia


A medium-sized moth, the Peppered Moth is renowned for its markings which provide camouflage against lichen-covered rocks and tree bark. It is on the wing between May and August in parks and gardens, woodland, scrub and hedgerows. The twig-like caterpillars feed on the leaves of a variety of trees and shrubs, including Silver Birch, oak, Bramble and Hawthorn. They have a deep cleft in their heads just like a broken stem, and legs that resemble thorns, making them perfectly camouflaged against the rose species they frequent.

How to identify

The Peppered Moth has a broad, furry body and long, narrow wings which it holds straight out to the side. It is usually whitish with intricate black markings all over, but some individuals are entirely sooty black (melanic forms). The similar Oak Beauty has two brownish bands on the wings, and holds its wings further back.
