The diagram shows the life cycle of the silkworm

The picture illustrates the various stages in the life of a silkworm.
Overall, there are 4 main stages in the life cycle of the silkworm, beginning with the laying of eggs and ending with the final stage as an adult moth.
At the first stage of the life cycle, eggs are laid by an adult moth on a mulberry leaf. After a period of approximately 10 days, the silkworm larvae emerge from the eggs and begin to feed on the mulberry
leaves. Next, about 4 to 6 weeks later, the larvae start to become covered in silk thread.
Then, once the larvae are completely covered in the silk thread, which takes between 3 and 8 days, a cocoon is formed. At the final stage, about 16 days later, the adult moth emerges from the cocoon. The adult moth will, in turn, lay eggs on mulberry leaves and the life cycle will begin again.
