Bombyx Mori or Silk Worm

• The commercial silk is obtained from cocoons secreted by the salivary glands of Bombyx mori, commonly known as the silkworm. 

• It is a species of moth whose larvae produce silk fibers. These fibers are spun into cocoons as part of the silkworm's natural life cycle. 

• The silk fibers are harvested from these cocoons and processed into various commercial products, making Bombyx mori the primary source of commercial silk production.
