The silk that is used in forming these cocoons is actually hardened silkworm saliva that has been secreted from the silk worm’s mouth. There is actually a small spinneret that is located on the silk worm’s lip, which is used to excreet the silk that they use to form their cocoon. This single strand of silk that the silk worm forms is about 1 mile long. Silk worms have to work in a figure 8 pattern in order to spin their cocoon around themselves.
While spending 3 weeks inside of the cocoon, they shed their skin and change into a pupa and then into moths. The moth will then emerge from its cocoon at dawn by secreting a special spit so that the silk can be dissolved and the moth can emerge.
