Within the cocoon, if the process is allowed to complete itself, the worm is changing into a moth and will emerge as an adult one to two weeks after entering the cocoon.

What do Hornworms turn into?

Where does worm Silk come from and how is it produced?

Worm silk is produced by the caterpillars of silk moths (Bombyx mori), whose eggs hatch into larvae that each spin one mile of continuous silk thread into cocoons. Silk farmers heat these cocoons to kill the silkworms and harvest thin threads. Spiders release silk from abdominal glands.

Which is stronger, silkworm silk or spider silk?

Scientists estimate spider silk is at least twice as strong as the type made by silkworms. Spider silk is extremely elastic and stronger than Kevlar and steel, neither of which stretch at all. Factors accounting for the varying scientific opinion about the strength of spider silk are easily explained.
