The main product of a silkworm is silk, a natural fiber produced from the cocoons spun by the larvae of the silkworm, notably the Bombyx mori. This intricate process begins when the silkworm consumes mulberry leaves and grows rapidly before entering the pupal stage, during which it secretes silk proteins to form a protective cocoon. Silk is renowned for its softness, luster, and strength, making it highly valued in textiles and fashion. The ancient practice of sericulture, or silk farming, originated in China over 5,000 years ago and remains an important industry worldwide.
