Assam

Assam produces some of the finest indigenous wild silks, mainly in golden Muga, Paat (mulberry), Tussar and Eri. 

Muga silk is the product of the silkworm Antheraea assamensis endemic to Assam. The larvae of these moths feed on som (Machilus bombycina) and sualu (Litsaea polyantha) leaves. The silk produced is known for its glossy, fine texture and durability. Very often the silk outlives its owner. Paat silk is produced by Bombyx textor silkworms which feed on mulberry (Morus spp.) leaves. It is usually brilliant white or off-white in colour. Eri silk is made by Samia cynthia ricini which feed on leaves of castor oil plant (Ricinus communis). It is also known as endi or errandi silk. Because manufacturing process of eri allows the pupae to develop into adults and only the open ended cocoons are used for turning into silk, it is also popularly known as non-violent silk.
