What changes have silkworm experienced in its life?

Silkworms have to go through eggs, ants, babies, cocoons and moths for more than forty days in their life.

The newly hatched silkworm babies are as black as ants, and we call them "ant silkworms". Their bodies are covered with fine hairs, which will not be obvious in about two days. Silkworm ants will have an appetite about 40 minutes after hatching, and then start the feeding process.

Silkworm babies feed on mulberry leaves After eating mulberry leaves continuously, the body gradually turned white and began to peel after a period of time. When peeling, they don't eat or move for a day or so like sleeping. This is called "dormancy". Once skinned, it is the second instar larva. Even if they are skinned once, they will increase by one year, and * * * will have to be skinned four times to become fifth instar larvae.

It takes two days and two nights for a five-year-old larva to cocoon, and the longest cocoon silk can be pulled 1.5 km! After about ten days, it appeared in the form of a silkworm moth and emerged from the cocoon. After cocoon emergence, the female moth emits odor to lure the male moth to mate, and the male moth dies after mating. The female moth spent about one night laying about 500 eggs, and then died slowly.
