Wild silk used to produce cloth. They usually produce a tougher and rougher silk than that from domesticated "Bombyx mori" silkworms. Wild silks are usually harvested after the moths have left the cocoons, cutting the threads in the process, so that there is not one long thread, as with domesticated silkworms. Wild silks are more difficult to bleach and dye than silk from "Bombyx mori", but most have naturally attractive colours, particularly the rich golden sheen of the silk produced by the muga silkworm from Assam, often known as Assam silk. The cocoon shells of wild silk moths are toughened or stabilized
Müller's larva Müller's larva Müller's larva or Mulleria is a larva of some Polycladida. It has 8-fold symmetry and is somewhat like a ctenophore. Müller’s larva is ciliated and has several paired and unpaired lobes. The cilia on the lobes are longer than cilia on the rest of the body. At the anterior and posterior ends of the larva are tufts of longer cilia (apical and caudal). The apical tuft originates from the apical organ, a sensory structure associated with the central nervous system. It is named after Johannes Peter Müller (1801-1858), a German physiologist who invented the plankton net, and first
