Moth will drink nectar. Some moths are farmed for their economic value. The most notable of these is the silkworm, the larva of the domesticated moth "Bombyx mori". It is farmed for the silk with which it builds its cocoon. , the silk industry produces more than 130 million kilograms of raw silk, worth about 250 million U.S. dollars, each year. Not all silk is produced by "Bombyx mori". There are several species of Saturniidae that also are farmed for their silk, such as the ailanthus moth ("Samia cynthia" group of species), the Chinese oak silkmoth ("Antheraea pernyi"), the Assam silkmoth
Bombyx mandarina Bombyx mandarina Bombyx mandarina, the wild silkmoth, is an insect from the moth family Bombycidae. It is the closest relative of "Bombyx mori" the domesticated silkmoth or "silkworm" (properly, this refers to the caterpillars only). Unlike the domesticated relative which is unable to fly or indeed persist outside human care, the wild silkmoth is a fairly ordinary lepidopteran. Its main difference from the domesticated taxon is the more slender body with well-developed wings in males, and the dull greyish-brown colour. "Bombyx mandarina" and the domesticated "Bombyx mori" constitute two of the currently identified eight species of the genus "Bombyx", the
