Main: (Geometridae / Ennominae)
70.274 [B&F: 1951] Grey Birch (Aethalura punctulata) ([Denis & Schiffermüller], 1775)

 

Notes: Common in birch woodland and heathland throughout Britain, most numerous in south-eastern England. Widespread and fairly common in Hampshire, but scarce on the Isle of Wight, with only one record so far this century. Wingspan 30-35 mm. Small size precludes confusion with all but Dotted Carpet Alcis jubata, which is whiter, with more conspicuous black marking, and Brussels Lace Cleorodes lichenaria, which has bolder, more strongly dentate subterminal fascia. Larva feeds on Downy and Silver Birch, and Alder, over-wintering as a pupa.
