Caterpillars make their cocoons out of silk from organs called spinnerets, which it then weaves together to make the cocoon itself.

The cocoon, formally known as the pupa or chrysalis, is the third stage of a butterfly's life cycle. The caterpillar spins a silk encasement from its mouth from which it hangs. It seems as though the caterpillar is resting but inside the cocoon, the caterpillar is undergoing major changes to become the beautiful butterfly it is destined to be!
