Here are the stages of a silkworm lifecycle
1. The female lays the eggs
2. A tiny black Caterpillar hatches out of the egg
3. The Caterpillar eats mulberry leaves and grows bigger, it goes through 4 molts.
4. The Caterpillar spins a cocoon of silk threads
5. inside the cocoon the Caterpillar changes into a pupa
6. The pupa changes into a moth, then the moth comes out
7. The adult moths mate with each other
