1. What is the growth and change process of a silkworm throughout its life?

The life cycle of a silkworm goes through four stages: (birth), growth and development, (reproduction), and death. This process is called the (life cycle) of the silkworm.

2. What is the growth process of silkworms?

The growth process of silkworms

1. The silkworm babies have hatched. The silkworm babies that have just hatched from the eggs are black and are called "ant silkworms". Their bodies are covered with fine hairs, which will no longer be noticeable after about two days.

2. The silkworm grows up. The silkworm feeds on mulberry leaves. After eating mulberry leaves continuously, its body turns white. After a period of time, it begins to shed its skin. The molting period lasts for about a day. It does not eat or move like sleeping. This is called "hibernation".

3. After the silkworm spins silk and molts once, it is a second-instar larva. It gets one year older each time it molts, and it has to molt four times in total to become a fifth-instar larva before it starts spinning silk and making cocoons. 4. It takes two days and two nights for a five-year-old larva to make a cocoon, and it molts for the last time in the cocoon to become a pupa. 5. About ten days after the silkworm breaks out of the cocoon, it emerges as a silk moth and breaks out of the cocoon. After emerging from the cocoon, the female moth emits a smell from its tail to lure the male to mate, and the male dies after mating. The female moth can lay about 500 eggs in about one night, and then it will slowly die.

3. What is the growth process of silkworms?

The growth process of silkworms is divided into four stages: egg, larvae, pupa and adult. 1. The silkworms hatch. The silkworms that have just hatched from the eggs are black and are called "ant silkworms". They are covered with fine hairs, which will no longer be obvious after about two days.

2. The silkworm grows up. The silkworm feeds on mulberry leaves. After eating mulberry leaves continuously, its body turns white. After a period of time, it begins to shed its skin. The molting period lasts for about a day. It does not eat or move like sleeping. This is called "hibernation".

3. After the silkworm has shed its skin once, it is the second-instar larva. It will age one year after each molting, and it will molt four times in total before it becomes the fifth-instar larva and starts to spin silk and make cocoons.

4. It takes a five-year-old silkworm larva two days and two nights to make a cocoon, and it sheds its skin for the last time in the cocoon to become a pupa.

5. About ten days after the silkworm breaks out of the cocoon, it emerges as a silk moth and breaks out of the cocoon.

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

4. What is the growth process of silkworms?

The growth process of silkworms:

Silkworm eggs → hatch into silkworm larvae → eat mulberry leaves and grow into adults → spin silk and make cocoons → turn into silkworm pupae in the cocoons → turn into silk moths after half a month → male and female silk moths mate and lay eggs and die within a few days (even if they do not mate or lay eggs, they will die within a few days).

5. What are the five stages of silkworm growth?

Sericulture is generally divided into five processes, namely silkworm eggs, silkworm ants, mature silkworms, silk cocoons and silkworm moths.

The outer layer of the silkworm egg is a hard eggshell, and the inner layer is yolk and serosal membrane; the ant silkworm is hatched from the silkworm egg, with many fine hairs, very small, and looks a bit like an ant; the mature silkworm is the larvae that have developed to the last stage, gradually stop eating mulberry, and the silkworm body shrinks and becomes slightly transparent; the silkworm cocoon is the cocoon of the silkworm, the sac-shaped protective layer of the silkworm pupae; the silkworm moth is formed in the cocoon, shaped like a butterfly

6. How do silkworms grow?

The growth process of silkworms is divided into four stages: eggs, larvae, pupae and adults. The silkworms that have just hatched from the eggs are black. They look like ants and are called ant silkworms. Their bodies are covered with fine hairs, which will no longer be obvious after about two days.

Silkworms feed on mulberry leaves. After eating mulberry leaves continuously, their bodies will gradually turn white, and after a period of time, they will begin to shed their skin.

It takes about a day to molt, and the larvae do not eat or move, just like sleeping. This is called dormancy. After molting once, they are the second-instar larvae. Each time they molt, they grow one year older. They molt four times in total, and then they become the fifth-instar larvae to spin silk and make cocoons. The five-year-old larvae need two days and two nights to make a cocoon, and molt for the last time in the cocoon to become a pupa. After about ten days, they break out of the cocoon and become silkworm moths.
