Insect life cycles: complete metamorphosis

Insect life cycles — complete metamorphosis in detail. Egg → larva → pupa → adult. The larva (caterpillar, grub, maggot) looks completely different from the adult. Inside the pupa the body is rebuilt. Butterflies, beetles, flies, and ladybirds all undergo complete metamorphosis.
