Cocoons are often stiffened to provide structural support and protection for the developing pupa inside. This stiffening is typically due to the silk proteins produced by the caterpillar, which harden as they dry. The rigid structure helps shield the pupa from predators and environmental factors while it undergoes metamorphosis. Additionally, the stiffness can assist in preventing fungal or bacterial infections during this vulnerable stage.

No More Cocoons was created in 1987.
