Typically this species has green wings with distinct dark bars but it can be quite variable and is often mostly dark brown with little green. The green coloration also fades over time. "Green, more or less dulled with black, the lines black, the postmedian forming sharper angles than in the two following (C. debiliata, C. agitata). Underside very sharply marked. - In ab. subaerata Hbn. the black markings are reduced, only the antemedian and the postmedian line developed. -In ab. cydoniata Bkh. the black is increased, particularly in the median area. - ab. cydoniata is entirely or almost entirely black."[2]

It flies at night in June and July and is attracted to light.
