Kokons

Kokons is the plural noun of the German and Dutch term kokon, which translates to cocoon in English. In those languages, kokon refers to the protective casing spun by certain insect larvae during pupation. In English-language biology, the related term cocoon is more commonly used, but Kokons may appear in multilingual texts or discussions of non-English nomenclature.

A cocoon is typically produced by silk secreted from the larval silk glands and serves to enclose the pupal stage of many moths and butterflies. Cocoons can vary in appearance, ranging from smooth, silk-only coverings to layered structures that may incorporate environmental materials such as leaf fragments. The interior of a cocoon creates a relatively humid microenvironment that helps protect the developing pupa and can cushion it from minor mechanical damage.

Not all Lepidoptera form cocoons. Some species undergo naked pupation, in which the pupa develops without a true cocoon or with only a minimal protective chamber. The presence, absence, and specific structure of a cocoon can reflect ecological factors such as humidity, predators, and habitat.

Cocoons have historical and economic significance in sericulture, where cocoons of certain moth species, particularly Bombyx mori, are processed to obtain silk fibers. Modern sericulture may involve a range of species with varying cocoon qualities and uses.
