## Definition

a soft, protective cover that some insects make to stay safe while they grow. It can also mean any place or feeling that makes you feel warm, safe, and hidden from the world.

For teachers: a protective silk envelope spun by the larvae of many insects, such as moths, as a chamber for pupation. In a figurative sense, it refers to a protective or comforting environment that provides insulation from external stress.

## Examples
