There are a series of fine black streaks that are variable in length and thickness. Hindwings fuscous, but occasionally lighter, with a fringe paler than ground colour.
Key Identification Features:
Flight Period: Beginning of June to mid-August.
Status: Recorded in all counties, but more commonly encountered in the east. Absent from most of the north and west with the exception of the Umbra, Londonderry and Crom Estate, Fermanagh.
Ecology: A grassland species, seen more frequently in coastal localities. Adults hide during the day among grassy tussocks and other dense vegetation. They are attracted to light and flowers, particularly those of Red Valerian Centranthus ruber and Buddleia Buddleja davidii. The larvae are nocturnal feeding during August and September on Cock's-foot Dactylis glomerata and probably other grasses. It overwinters as a larva.
