Early Stages of Common Leopard

The larva of Leopard butterfly usually feeds on immature to middle age leaves of host plant.

The female butterfly lays eggs on the immature leaves or young shoots of host plant. It takes about 2-3 days to hatch. The newly hatched caterpillar eats its egg shell as the first meal. It (which is not shown here), is having a black head capsule and yellowish body. Initially its body length is around 1.5 mm which increases up to 3- 3.2 mm before moulting to 2nd instar. It takes about 2 days for 1st instar caterpillar to reach the second instar.
