Common on roadside verges, woodland edges and waste ground throughout the British Isles. Probably under-recorded in Hampshire and on the Isle of Wight, where the extent of known records correlate with those areas in which the recording effort is concentrated. Wingspan 11-13 mm. Well-marked males, with dark head and centrally weak fascia are distinctive, but poorly marked specimens can only be identified by dissection of the genitalia. Larva mines leaves of Cock's-foot.
