Description

Family: Geometridae (ABH : 70.283)

Wing span: 36 - 52mm

This moth is unmistakably greenish-white when fresh, but fades to whitish a few days after emergence. The hooked, reddish forewing tip, and the straight white cross-lines distinguish it from other emeralds.

It is found throughout the British Isles.

It is most abundant in broad-leaved woodland, but is also found in most other situations where trees and shrubs grow.

It over-winters as a small larva on the foodplant. There are two generations in the south, late May to early August, and early August to early October.

Larvae feed on a wide range of trees and shrubs, including oaks, Hawthorn, Blackthorn, Hazel, birches, elms, sallows, Horse-chestnut, Sweet Chestnut and Beech.

Earliest UK sighting: 22nd May ; Latest UK sighting: 18th September
