Status and ecology:

A resident species usually occurring sparingly or fairly commonly at mv light, but it is sometimes common in woods and bushy places; much less frequent along treeless parts of the coast. Generally distributed in large areas, but very local in numbers. This species is double or triple-brooded according to season, flying mainly from the second week of March to late April and again from late June to the third week of August. The episodic partial third generation has become increasingly recorded, from early September to late October. Adults have been seen in every week from mid February to the third week of May and from late June to late October. Larvae positively identified as bistortata feed on sweet chestnut. A wide variety of other trees and shrubs have also been listed from elsewhere. (Pratt, 2011)
