This is a fairly large species, the forewings varying from pale greyish brown to almost black and cryptically patterned. All but the darkest individuals usually have an obvious black mark close to the dorsum and a pale "zig-zag" subterminal line. The hindwings are whitish with darker venation and a dark shaded band at the margin. This moth flies at night from June to August with a second brood sometimes emerging in September and October. It is attracted to light, sugar and many nectar-rich flowers.Food
The larva is pale with a black head and black spots. It feeds on various grasses including "Deschampsia", "Dactylis glomerata", "Lolium" "Calamagrostis" and "Festuca" species. This species overwinters as a larva.References:
