The life of a silkworm goes through 4 stages: egg, larva, pupa and adult. The larval stage of the silkworm is what people call the silkworm baby stage. What is usually called sericulture refers to the rearing of the larvae. From hatching to cocoon spinning, the larva must go through 4 molts. People therefore divide the course of the larva into 5 instars. During the period before molting, the silkworm does not eat or move, which is called sleeping. From the first to the fourth instar, the silkworm must sleep 4 times; in the later stage of the fifth instar, it no longer sleeps, but spins silk and forms a cocoon, and pupates inside the cocoon, thereby completing the larval stage of the silkworm. Newly hatched silkworms are called ant silkworms, and newly molted
