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
Flacherie Flacherie Flacherie (literally: "flaccidness") is a disease of silkworms, caused by silkworms eating infected or contaminated mulberry leaves. Flacherie infected silkworms look weak and can die from this disease. Silkworm larvae that are about to die from Flacherie are a dark brown. There are two kinds of flacherie: essentially, infectious (viral) flacherie and noninfectious ("bouffee") flacherie. Both are technically a lethal diarrhea. Bouffée flacherie is caused by heat waves ("bouffée" means "sudden heat spell" in French). Viral flacherie is ultimately caused by infection with "Bombyx mori" infectious flacherie virus (BmIFV, Iflaviridae), "Bombyx mori" densovirus (BmDNV, Parvoviridae) or "Bombyx mori" cypovirus
