What is the difference between tasar, eri and muga silk and which suits my area?

These are the non-mulberry (vanya) silks and each uses different host plants and conditions. Tasar silkworms feed on forest trees like Arjun and Asan and are reared largely outdoors in forest and tribal belts of Jharkhand, Chhattisgarh and Odisha, giving the coarse golden tasar silk. Eri silkworms feed mainly on castor (and tapioca or kesseru), are reared indoors, are hardy and relatively easy, and give eri (often spun, not reeled) silk; eri suits the Northeast and also castor-growing areas. Muga is the special golden silk of Assam, reared on som and soalu trees, and is region-specific to Assam and nearby. For a forest or tribal area like yours, tasar is often the natural fit because of the host trees; eri is a good choice if castor grows well.
