Life Cycle of a Silk Worm
Silk is a natural fibre which comes from the cocoons of silkworms, which are the larvae of the mulberry silk moth Bombyx mori.
Life Cycle of a Silkworm
- A female moth lays 300-500 tiny eggs and after around 10 days, the larvae (silkworms) hatch.
- The silkworms feed solely on large amounts of leaves from the mulberry tree for around 30-40 days.
- The silkworms shed their skin up to four times, or molt, as they continue to eat and grow.
- After their final molt, the silkworm builds a cocoon around itself. The cocoon is a protective casing spun from silk.
- Inside the cocoon, the silkworm changes into a pupa, the stage between larvae and adult moths.
- After around two weeks, the pupa emerges from the cocoon as an adult moth.
- The adult moth looks for a mate so that the female can lay more eggs and begin the cycle again.
