Sequence of growth and change of silkworm
Silkworm babies, also known as silkworms and silkworms, are completely abnormal insects that feed on mulberry leaves and go through four stages of development with completely different shapes and physiological functions: eggs, larvae, pupae and adults. Let's take a closer look at the pictures of the growth process of silkworm babies!

Silkworm babies reproduce with eggs. Silkworm eggs look like fine sesame seeds, with a width of about 1 mm and a thickness of about 0.5 mm When the temperature rises, silkworm eggs begin to develop. After 7- 15 days, the silkworm eggs become transparent and the outline inside can be seen, which means that the silkworm baby is coming out soon!

The young silkworm just hatched from the egg is as black as an ant. We call it ant silkworm. It is covered with fine hairs, which will not be obvious in a few days.

Silkworm ants have an appetite about 40 minutes after hatching, and the feeding process is about to begin.

Silkworm babies feed on mulberry leaves Keep eating mulberry leaves, the body turns white, and after a while it begins to peel off.

Silkworms can't eat when they sleep. The surface is sleep. In fact, they take off their old skins and put on new ones to continue to grow.

Silkworm babies molt four times during the whole feeding process. I can't eat anything every time I molt. Try not to disturb them at this time, and don't throw them away just because they are sick.

Each sleep period of silkworms lasts about one day.

Once skinned, it is the second instar larva. If she peels her skin once, she will be one year older, and * * * will have to peel it four times before she becomes a fifth instar larva.

Generally, cocoons begin to form in about 25 days.

When the silkworm baby's back is shiny and yellow, it means that it is necessary to spin silk and cocoon. At this time, it is necessary to provide a cross space for silkworm babies to cocoon.

It takes two days to form a complete cocoon and molt into pupa for the last time in the cocoon.

About ten days later, it appeared in the form of a silkworm moth and came out of the cocoon.

After the cocoon comes out, the female moth's tail emits a smell to lure the male moth to mate, and the male moth dies after mating. It takes a female moth about one night to lay about 500 eggs, and then she will die slowly.
