<P> Despite being notorious for eating clothing, most moth adults do not eat at all . Many, like the Luna, Polyphemus, Atlas, Promethea, cecropia, and other large moths do not have mouth parts . While there are many species of adult moths that do eat, there are many that will drink nectar . </P> <P> 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 . As of 2002, the silk industry produces more than 130 million kilograms of raw silk, worth about 250 million U.S. dollars, each year . </P> <P> 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 (Antheraea assamensis), and the Japanese silk moth (Antheraea yamamai). </P> <P> The larvae of many species are used as food, particularly in Africa, where they are an important source of nutrition . The mopane worm, the caterpillar of Gonimbrasia belina, from the family Saturniidae, is a significant food resource in southern Africa . Another saturniid used as food is the cavorting emperor (Usta terpsichore). In one country alone, Congo, more than 30 species of moth larvae are harvested . Some are sold not only in the local village markets, but are shipped by the ton from one country to another . </P>
