The silkworm is the larva stage of the silk moth's life cycle. Moths lay eggs which develop into the silkworm larvae, grub or caterpillar (commonly called silkworms). They eat for 20-30 days, consuming large amounts of mulberry leaves, and molt through four changes of skin or 'instars'.

LIFE CYCLE OF SILK MOTH { SILK WORM}.
======================================



 Actually silkworms are not worms, but the larvae or caterpillars hatched from the eggs of the silk moth. The life history of a silk moth starts when a female silk moth lays eggs.

The larvae or caterpillars hatched from the eggs of the silk moth. These silkworms feed on fresh mulberry leaves the silkworm grows in size and then becomes a pupa.

In the pupa stage, it weaves a net to hold itself.  It then swings its head from side to side, secreting a fibre that hardens on contact with air. This fibre is made of a protein and becomes the silk fibre.

The caterpillar covers itself completely with silk fibre and turns into a pupa, this covering is known as the cocoon. The moth continues to develop within the cocoon. The silk thread or yarn is obtained from the silk moth’s cocoon......
