cocoon

kuh-KOON/kəˈkuːn/

A protective enclosure, especially one spun by an insect.

The caterpillar spins a silk cocoon around its body.

A close view of a moth larva enclosing itself in an oval silk cocoon attached between two small twigs.
Etymology

The shell image connects the cocoon with an enclosing outer case: the larva's silk forms a protective covering, much as a shell encloses an egg or nut.
