Silkworm life goes through four stages:

Silkworm eggs → silkworm → silkworm chrysalis → silkworm moth.

How long does each stage of silkworm take?

The growth and development of silkworms are related to temperature, humidity and food. The general incubation period is ten to eleven days. The larval stage is about 25 days (specifically, the first instar is four to five days; The second age is three to four days; Three years and four days; Four years and six days; The fifth instar lasts seven to nine days. ) Pupal period 14 to 18 days. The moth period is three to five days.

Silkworm moths stop eating after emergence, and their wings will harden after about an hour. When the wings are hard, they mate. Each female moth lays about 300 ~ 400 eggs. The purpose of silkworm emergence into moth is to mate and lay eggs.
