Males and females are kept in the same vessel only for breeding: they are never left together in a cage, because the male ceases to sing when thus mated, and will die in a short time after pairing.[2]
The breeding pairs are kept in jars or other earthen vessels half-filled with moistened clay, and are supplied every day with fresh food. They do not live long: the male dies first, and the female survives only until her eggs have been laid. The young insects hatched from them, shed their skin in about forty days from birth, after which they grow more rapidly, and soon attain their full development. In their natural state these creatures -are hatched a little before the Doyō, or Period of Greatest Heat by the old calendar,—that is to say, about the middle of July;—and they begin to sing in October.
