Cocoon

the protective formation of the pupae of many insects. The cocoon is usually woven of silk thread secreted by the larva before pupation. Cocoons of this type are those of many butterflies that spin cocoons, moths, silkworms, and some ants, whose cocoons are mistakenly called ant eggs. Many beetle larvae, such as weevils of the genus Cionus, construct cocoons of mucus secreted at the time of pupation. In some insects, pupation occurs inside the casing in which the larva has lived, for example, the sac casings of bagworm moths. The pseudo-cocoons, or puparia, of many flies consist of the skins of the larvae left after molting.

Earthworms, leeches, spiders, and some mollusks form “egg cocoons,” inside which eggs develop.
