The wings have scalloped margins, and the forewings have slightly hooked wingtips. Some moths have a dark spot near the middle of each forewing, The males have a wingspan of about 4 cms. The females have a wingspan of about 6 cms.
The eggs are white and nearly spherical, with a black cap. The eggs have a diameter of about 0.5 mm.
