The life cycle of silkworm

This is the first stage of a silkworm’s life cycle. The female moth lays eggs which are the size of a small ink dots! The female can lay more than 350 eggs at a time. These eggs remain dormant till springtime when the warmth in the air arouses them to hatch. This happens once a year. But due to human intervention the breeding of silkworm and hatching of eggs takes place at least thrice a year.
When the eggs crack there emerges a hairy silkworm. This larva stage is the one where growth takes place. Upon hatching, a silkworm is 1/8th of an inch. They feed on tender mulberry leaves. They consume large amount of these leaves for 20 to 30 days and go through four stages of molt or skin changes. The first molt is when the silkworm sheds all its hair and attains a smooth skin.
At this stage the silkworm spins a protective cocoon around itself. It is made by a single thread of silk and it the size of a small cotton ball. This, it does to protect itself from predators. This is the stage where the second molt takes place when the lava turns into a pupa inside the cocoon.
This stage is the motionless stage just before adulthood. It is at this stage when people take the cocoon and plunge it into boiling water to kill the pupa and unwind the silk thread. But if they don’t the pupa rests peacefully for 2-3 weeks after which it metamorphoses into an adult moth.
The pupa changes itself into a beautiful adult moth. These moths are flightless and do not have a mouth so they are unable to consume food. Once the adult moth comes out its sole purpose is to find a mate. Within 24 hours of mating a male moth dies while the female lays eggs and then even she dies. Thus the lifecycle of a silkworm begins again.
