Grey Birch Aethalura punctulata

([Denis & Schiffermüller], 1775)

Wingspan 30-35 mm.

A smallish species, with a mottled grey ground colour and three darker transverse lines.

Fairly common over much of England and Wales, scarcer and more local in Ireland and Scotland.

The adults fly in May and June, and frequent wooded habitats. Birch (Betula) is the main foodplant, but occasionally alder (Alnus glutinosa) is used.
