Description

The notched and hooked forewings of this species create a very distinctive outline, but the depth of the emargination varies, and can even be absent.

The pronounced emargination on the costa of the forewing is therefore distinctive of this species

The species has recently been split from 1062a E. effractana, which is more of a northern species

   

Life Cycle

Flying from July to September, the species is commonest in the south of Britain, becoming less common further north The larvae feed on the leaves and shoots of trees such as sallow (Salix), poplar (Populus) and birch (Betula).

 

Habitat

Common in woodland, gardens and hedgerows throughout the British Isles, less numerous in the north. Larva feeds on Sallow, Poplar and Birch, living within a spun or rolled leaf.
