Silkworms, also called mulberry silkworms and domestic silkworms, are completely metamorphosed insects that feed on mulberry leaves. They go through four developmental stages with completely different morphological and physiological functions: eggs, larvae, pupae, and adults. Below we will discuss Let’s take a look at the detailed pictures of the growth process of silkworm babies!

Silkworm babies reproduce with eggs. Silkworm eggs look like fine-grained sesame seeds, about 1 mm wide and 0.5 mm thick. When the temperature rises, silkworm eggs begin to develop. After 7-15 days, when When the silkworm eggs become transparent and the outline inside can be seen, it means that the silkworm babies are about to come out!

The silkworms that have just hatched from the eggs are as black as ants. We call them ant silkworms. They are covered with fine hairs. The hairs will not be obvious after a few days.

Silkworm ants will have an appetite about 40 minutes after emerging from the shell, and the feeding process will begin at this time.

Silkworm baby lives on mulberry leaves. After constantly eating mulberry leaves, her body turns white. After a while, she begins to peel.

Silkworms do not eat or move when they sleep. On the surface, they are sleeping, but in reality they are shedding their old skin and replacing it with new ones to continue growing.

The silkworm baby will molt 4 times during the whole raising process. It will not eat during each molt. Try not to disturb it at this time, and do not throw it away because you think it is sick.

Each sleep period of silkworms lasts about one day.

After one molt, it becomes the second instar larvae. She sheds her skin once, which means she is one year older. She has to molt four times until she becomes the fifth instar larvae before she starts to spin silk and form a cocoon.

Cocoons usually begin to form in about 25 days.

When the silkworm's back is shiny and yellow, it means that it is about to spin silk and form a cocoon. At this time, a cross space should be provided for the silkworm to form a cocoon.

It takes two days to form a complete cocoon and complete the final molt in the cocoon to become a pupa.

About ten days later, it emerges as a silkworm moth and emerges from the cocoon.

After emerging from the cocoon, the female moth emits a smell from its tail to attract the male to mate. The male will die after mating. The female moth can lay about 500 eggs in about one night, and then she will die slowly.
