A resident with adults generally occuring singly or sparingly in a wide range of habitats in both vice-counties, but they are occasionally common at Rewell Wood and often common or even very common at mv light in Friston Forest. Well distributed in the far west but only patchily found elsewhere. Mainly single -brooded, flying most numerously from late May to mid August, although a partial second emergence sometimes appears throughout September. Adults have been seen during every week from the second week of April to late September. Larvae feed on Beech. (Pratt, 2011)
