Common wherever there is bracken, in woodland, heathland and moorland throughout much of the British Isles. In Hampshire and on the Isle of Wight extremely common amongst bracken everywhere - in fact one of the few species of insect that feeds on this plant. Well-recorded as it is easily disturbed by day. Wingspan 31-37 mm. Fairly unmistakable. Larva feeds on Bracken, over-wintering as a pupa.
