This is a very variable species, both in size (wingspan 28–38 mm) and colour. The ground colour of the forewings varies from pale buff to dark or reddish brown with three narrow fascia. The area between the inner two fascia is sometimes much darker than the surrounding ground colour and is marked with stigmata, often quite indistinct. Melanic forms occasionally occur. The hindwings vary from pale cream to dingy brown. This moth flies at night from July to September [1] and is attracted to light and sugar and sometimes to nectar-rich flowers.

The larva is green with yellow lines and black and white spots. It feeds on a variety of plants, chiefly trees and shrubs (see list below) and also on the larvae of other Lepidoptera species, even occasionally its own species. The species overwinters as an egg.
