Common in woodland, scrub, hedgerows and gardens throughout much of the British Isles. In Hampshire and on the Isle of Wight widespread and common in wooded country in the three vice-counties, but doubtless still under-recorded because of the lateness of its flight period. Wingspan male 36-38 mm, female 42-48 mm. Unmistakable: no similar species fly so late in the year. Larva feeds on many deciduous tree species, including birch, oak, hawthorn and blackthorn.
