Question

Answer explain the life cycle of a silkworm

Answer 1

There are four stages in the life-cycle of a silk moth - egg, caterpillar, pupa and adult.
The female silk moth lays hundred of eggs on the mulberry leaves. The larvae that hatched out in 3-5 days are called caterpillars.
Caterpillar feed on mulberry leaves and grow in size. When the caterpillar is ready to enter the pupal stage, it stops feeding and its salivary gland starts secreting a sticky fluid called fibroin. This fluid hardens on exposure to air and forms a long thread of silk. This thread gets wrapped around it's body to form a ball-like structure called cocoon. At this stage, the caterpillar becomes a pupa.
The silk moth continues to develop inside the cocoon.
At the end of pupal stage, the silk moth cuts open the cocoon and the young moth flies out.

Answer 2

Answer:

The life cycle of silk moth starts when a female silk moth lays eggs. The caterpillar or larvae are hatched from the eggs of the silk moth. The silkworms feed on mulberry leaves and give rise to pupa. In the pupa stage, a weave is netted around by the silkworm to hold itself.
