The larvae are gregarious in nature and feed on leave surface. Larval period lasts for 24-27 days in summer and 50-52 days in winter. The larva is green in colour when fully grown measures about 2cms in length. It pupates inside the soil by making an earthen cocoon around itself.

During summer the development occurs rapidly
