Wild silk either by tanning (cross-linking) or by mineral reinforcements (e.g. calcium oxalate). Recently, a new method has been developed, demineralizing, which can remove the mineral reinforcements present in wild silks and enables wet reeling like the commercial silkworm "Bombyx mori". Wild silks are often referred to in India as 'Vanya' silks: The term 'Vanya' is of Sanskrit origin, meaning untamed, wild, or forest-based.

Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form ("e.g." caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae
