When silk obtained from silk moth?

Silk is obtained from the cocoon of the silkworm, which is the larval stage of the silk moth (Bombyx mori). After the larvae spin their cocoons, they undergo metamorphosis into moths. To harvest silk, the cocoons are typically boiled or steamed to kill the pupa and loosen the silk fibers, which are then carefully unwound and processed into silk thread. This process has been practiced for thousands of years, primarily in countries like China and India.
