Silk

Silk is one of the most delicate, popular, strong, soft, shiny, and expensive fibres obtained from silkworms. The rearing of silkworms for obtaining silk is called sericulture. The steps in the life cycle of a silkworm are Egg → Silkworm → Pupa → Adult Moth. When a female moth lays eggs, its life cycle starts, and larvae secrete a fine filament made of fibroin protein that forms cocoons.
