A cocoon is a casing spun of silk by many moths and caterpillars, [16] and numerous other holometabolous insect larvae as a protective covering for the pupa. Cocoons may be tough or soft, opaque or translucent, solid or meshlike, of various colors, or composed of multiple layers, depending on the type of insect larva producing it.
Pupae Silkworm cocoons weighed and sorted (Liang Kai's Sericulture) Silkworm breeding is aimed at the overall improvement of silkworms from a commercial point of view. The major objectives are improving fecundity, the health of larvae, quantity of cocoon and silk production, and disease resistance. Healthy larvae lead to a healthy cocoon crop.
