The eggs are laid singly or in rows on leaves. The pupa is dark green and hangs from the leaf. The damage is done mainly during vegetative stage of the crop. The caterpillar damages the crop by either completely eating the leaves or leaving the mid rib after eating the lamina on both sides. The damaged crop presents gazed look similar to that of grasshopper and armyworms. In heavily infected crops, plants may regrow foliage but panicle initiaiton is delayed.
