"The Life Cycle of Silkworms" Animal Life Cycle PPT Courseware

1. Silkworm babies hatched

The black silkworms that have just hatched from the eggs are called "ant silkworms" and are covered with fine hairs. The hairs will disappear after about two days.

2. Silkworm babies grow up

Silkworms feed on mulberry leaves. As they continue to eat mulberry leaves, their bodies turn white, and after a while they begin to peel.

Silkworm life cycle

The ant silkworm hatched from the silkworm egg is the beginning of the silkworm's life cycle. When the silkworm reaches a certain stage of growth and development, it will form a cocoon and turn into a pupa. When the pupa develops into a moth, the moth will crawl out of the cocoon, and then the silkworm moths will mate and give birth. The death of eggs and silkworm moths is the end of silkworm life.

A silkworm’s life has gone through:

Birth--Growth--Reproduction--Death

This whole process is the life cycle of silkworm. The life cycle of silkworm is about 56 days.
