The adult moth of this species is pale grey or brown, with variable vague wavy dark lines. Some specimens have a pale band along each forewing costa. Specimens of Ectropis calida have a dark submarginal line on each forewing that is only slightly kinked at the central blurry dark blotch. Also the dark submarginal line on each hindwing is nearly straight, rather than curved as in other species in Ectropis. Like most geometrids, the moth rests with wings outspread. The wingspan is about 2.5 cms.
