This is a variable species, the forewings ranging from pale buff to dark brown although the paler forms are generally more common. The forewings are usually marked with two dark stigmata and a black streak near the apex. The hindwings are whitish marked with dark patches which are rather fancifully likened to a lunar landscape. The wingspan is 32–38 mm. This moth flies at night from August to October [1] and is attracted to light and flowers.

The larva feeds on all parts of various grasses, overwintering in this form.
