Life cycle of a silk worm

Science Project/Science Experiments Life cycle of a silk worm or silk moth The life cycle of the silk moth has several stages from egg to adult moth over a period of about six to eight weeks. Let us learn about various stages of the life cycle of the silk moth. Stage 1: The female silk moth lays tiny eggs. Satge 2. The eggs will begin to hatch about two weeks after being laid. A tiny caterpillar comes out when the egg hatches. These tiny caterpillar are called silkworm or Larva Stage 3: The silkworm feeds on mulberry leaves and grows bigger within three to four weeks. Stage 4: The caterpillar then secretes a fibre made of protein which hardens when exposed to air. The caterpillar weaves the fibre around itself through figure of eight movement of head forming a cocoon. Stage 5: The caterpillar takes three to seven days to prepare the cocoon. Inside the cocoon the caterpillar changes into a pupa. Stage 6:. A few weeks later the cocoon opens and an adult moth come out. Silk threads are obtained from the cocoon of silkworm.
