Common in hedgerows and scrub throughout the British Isles. The distribution in Hampshire mirrors those areas in which trapping effort is concentrated, and the moth is probably more widely distributed than the records suggest; very infrequently recorded from the Isle of Wight. Wingspan 13-16 mm. Distinguished from the various Swammerdamia species by the dark-bordered orange spot on the wing-tip, and the rows of fine longitudinal dashes along the length of the forewing. Larva mines the foliage of Blackthorn, subsequently living within a silken web, often several together, over-wintering as a pupa in a cocoon.
