The larvae feed on Canavalia galeata, Dolichos lablab, Erythrina monosperma, garden bean, Mucuna gigantea and Strongylodon lucidum. They feed beneath a turned over portion of a leaf of their host plant or between leaves that are in close contact, which they web together. Then they feed on the leaf substance leaving only the outer epidermis. The larvae are about 22 mm long and dark green.

Pupation takes place in the larval shelter. The pupa is about 9 mm long and medium brown. The pupal period lasts 11–13 days.
