Silk is a natural fibre which comes from the cocoons of silkworms, which are the larvae of the mulberry silk moth Bombyx mori.

- 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.

- The thread from a mulberry cocoon when unwound can be 900 metres long

 

-  Over 50,000 cocoons are needed to make 1 kg of silk

 

- To feed 25 silkworms from egg to the cocoon stage you need a 10 foot mulberry tree or 2 small bushes to provide enough leaves.

 

-  A silkworm increases its size 10,000 times before it is ready to spin its cocoon. A small branch will most probably last a week and it takes 4 weeks for the silkworm to grow before it spins a cocoon.
