Silkworms are the larvae, or caterpillars, of the silkmoth.


Silkmoths have been domesticated for thousands of years and are used to produce silk.


When it matures, each silkworm forms a cocoon which is made from a single thread of raw silk, 300 to 900 metres long.


These cocoons are harvested and the silk is unwound, usually after boiling in water which kills the larvae inside and softens the fibre. The silk threads are twisted together to form something thick enough for spinning and weaving.


A sustainable form of silk production allows the silkworms to develop into moths and hatch from the cocoons. Silk is a protein, so the larvae use protease enzymes to dissolve a hole in the cocoon.


This means only much shorter fibres can be harvested, and the silk produced can never be so smooth and shiny because the threads will have many joins.
