This is a variable species, the forewings ranging from yellow to reddish brown and marked with paler stigmata and fascia. The most distinctive marking is a dark discal spot, with a diffuse dark band linking it to the costa. The hindwings are dirty grey with pale cream margins. The wingspan is 34-44 mm. This moth flies at night from August to October and will come to light but is more strongly attracted to some flowers and sugary foods.
