Key Identification Features:
Flight Period: Mid-June to the beginning of September.
Status: Common and widespread throughout southern and eastern counties. Apparently scarce in Tyrone and Londonderry although this may be due to under-recording.

Adults come frequently to light in moderate numbers and are occasionally found by day resting on rocks and the trunks of trees. The larvae can be found in April and May on Bilberry Vaccinium myrtillus, willowherb Epilobium spp. and Sea Campion Silene uniflora. It overwinters as an egg.
