The species that are most used are the white mulberry {Morus alba), of which there are several varieties, and the black mul- berry {Morus ni- gra)] the former is the better. The leaves of osage orange {Madura aurantiaca) have also been used as silk-worm food to a considerable ex- tent.

The newly-hatched larva is black or dark gray, and is covered with long stiff hairs, which spring from pale-colored tubercles. The hairs and tubercles are not noticeable after. VIII.
