The metamorphosis of butterflies?

The metamorphosis process of butterfly is egg, larva, pupa and adult.

Female butterflies lay eggs after mating. The eggs are round or oval, with a waxy shell on the surface to prevent water evaporation and a fine hole at one end. Generally, eggs are laid on the leaves of plants that larvae like to eat to prepare food for larvae.

After the eggs hatch into larvae, they mainly eat and eat many plant leaves. As larvae grow, they usually molt several times.

Larvae will become pupae when they mature. Larvae usually stays in a hidden place on the back of plant leaves, and then it will pupate directly without cocooning.

When the pupa matures, it breaks out of its shell and becomes a butterfly. But it takes some time to dry and harden the wings. When the wings are spread, the butterfly can fly.
