Q.Which silkworm produces muga silk, and what is special about the colour of this silk?

Assam produces two special non-mulberry (vanya) silks. Muga silk comes from Antheraea assamensis, is a natural golden silk endemic to Assam (GI-tagged 2007), and is reared semi-domesticated on Som (Persea bombycina) and Soalu (Litsea polyantha). Eri silk comes from the fully-domesticated Samia ricini reared on castor and kesseru; because the moth is allowed to leave the open-ended cocoon and the silk is spun (not reeled), eri is called 'ahimsa' or peace silk, and is warm and wool-like.
