Resident. Usually occurs singly or sparingly in most places but it is often common and sometimes very common in Friston Forest. Thinly distributed, very local, and irregular in numbers. Seriously decreasing. Generally double-brooded, flying mainly from the second week of May to the same week in June and again from mid July to mid August. Specimens seen in flight throughout September seem to be representatives of a third emergence. Adults have been seen in every week from late April to late September. Larvae fees on beech.
