Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) is a cosmopolitan pest. It is variously known as gram caterpillar or pod borer, cotton bollworm, Corn earworm, and tomato fruit worm. It does very serious damage to many cash crops and horticultural crops. There are four stages of this H.armigera – egg, larva, pupa, and adult – that make up the process of complete metamorphosis. The journey from the last larval instar to the pupa is shown in this video. it is captured during my Ph.D. @ Pulse lab, Entomology, GBPUAT, Pantnagar,
