A resident that usually occurs sparingly but it is sometimes fairly common to common at mv light in a wide range of habitats. Probably generally distributed, but very local in any numbers. Double-brooded, the main flight appearing from the second week of June to early September. A partial second emergence flies throughout september, sometimes to mid october. Adults have been seen in every week from the second week of June to the third week of October. Larvae feed on Burnet Saxifrage and Beaked Parsley. (Pratt, 2011)
