Tussar silk also known as (Sanskrit) Kosa Silk is produced from larvae of several species of silk worms belonging to the moth genus Antheraea, including A. mylitta, A. pernyi, A. roylei and A. yamamai. These silkworms live in the wild forest in trees belonging to Terminalia Species and Shorea Robusta as well as other food plants like Asan, Arjun, Jamun , eating off the leaves of the trees they live on. Tussar is valued for its rich texture and natural deep gold colour.
