The wingspan is 20–22 mm.
Full-grown larvae are 13–18 mm long and their wingspan is generally about 24–28 mm. It can be confused with the cream-bordered green pea (Earias clorana) or the spiny bollworm (Earias biplaga).[1]
Pupation takes place in a felt-like cocoon, which is attached to dry leaves of the food plant or to plant debris on the ground. Typically, the pupal stage takes 9–15 days, but may extend to up to two months if development is delayed by low temperatures.
