A cocoon is like a cozy sleeping bag made by many moths. When a caterpillar is fully grown, it finds a safe spot and wraps itself in sticky silk. Inside, it becomes a pupa, its body changing into an adult moth. When the moth is ready, it breaks out of the cocoon. Its crumpled wings then fill with fluid, causing them to stretch out and dry. Then the moth can fly and explore the world.
