Do silkworms have eyes? Whether silkworms have eyes or not

Silkworms have eyes. The silkworm's eyes grow on the head, very close to its mouth, and there are six single eyes on the left and right sides. However, its eyes are not well developed, and it only has some photoreceptor cells, so it can only feel the intensity of the light, and cannot see the surrounding things clearly.

In addition, the black dots that grow on the sides of its body are its stomata that allow it to breathe, not its eyes. In the process of raising silkworms, you can observe with your heart, and you will definitely find something, or pay more attention to observation, so that you can understand more clearly.

Habits of silkwormsSilkworm. Living on mulberry leaves, the body will turn white after eating mulberry leaves, and after a period of time, it will begin to peel. When the skin is peeled, it takes about a day to not eat or drink like sleep, which is called "dormancy".

After a peel, it is a second-instar larvae. Even if it sheds its skin once and increases its age by one year, the larvae have to shed their skin four times to become a fifth-instar larva, and then eat mulberry leaves for 8 days to become a mature silkworm and begin to spin silk and form cocoons.

You must know that the eyes of silkworms are different in the worm stage and the adult stage. The insect stage is single-eyed, with 6 on each side of the head, and can sense the intensity of light. The adult stage is a compound eye, and a compound eye is composed of more than 3,000 small eyes, with a wide field of vision.

Our science teacher said that silkworms have six single eyes.

On both sides of the mouth, the small ones are very small. Almost invisible, two.

There are eyes, on the head.

silkworms, which are divided into two categories; A type of silkworm, that is, mulberry silkworms. It feeds mainly on mulberry leaves. The other type is called mountain silkworms, that is, quercus silkworms, which feed on oak leaves.

Silkworms go through 4 stages in their life: eggs, larvae, pupa and moths. It is the larva of silkworm moth, the main raw material of silk products, and has an important position in human economic life and cultural history.

Native to southern China, the ancient text records that the emperor Xuanyuan began to raise silkworms, and the most famous in the south of the Yangtze River is the well-known wife of the Yellow Emperor. The staple food of mulberry silkworms is mulberry leaves, which can also be supplemented with a small amount of castor leaves. The cocoon is woven from a continuous silk with a length of about 300,900 metres (1,000,300 ft).

The adults and pupae of silkworms are edible and have therapeutic effects. Silkworm moths lay eggs and mate to reproduce offspring, and die after laying eggs. Because of its long history and economic importance, silkworm breeding has become an important object of modern scientific research.

Yes.

The silkworm has eyes, and the main place is on its head, not far from its mouthparts, and six single eyes can be seen on the left and right sides. It's just that its eyes are not so developed, that is, there will be some light-sensitive cells, and the main purpose is to feel the light, and it can't see the surrounding things better.

At the same time, black dots can be seen on both sides of its body, which represents the air holes, which can also make it breathe, and this is not its own eyes. Moreover, there are many important organs on its head, each of which has its own function, just like its upper lip and lower lip can be seen in the lower part of the chain head, among which the upper lip is mainly used to hold the blades.

The growth process of silkworms

1. Egg stage

Silkworms start to hatch from eggs, the newly laid silkworm eggs are white and transparent, the size is like sesame seeds, densely arranged together, in the process of incubation, the silkworm eggs gradually turn black, it means that the young silkworms are developing, waiting for maturity, will drill out of the egg shell to feed.

2. Silkworm stage

The newly hatched silkworm is black, about 3 mm long, the whole body has fine hairs, feeds on the fresh mulberry leaves, after growing for a period of time, the young silkworms will become gray-white, blue-white, need to supplement the mature mulberry leaves with more fiber content, wait for the young silkworms to molt 4 times, the whole body is shiny, and it will enter the stage of spinning silk cocoons.

3. Pupal stage

Before the young silkworms spin silk, they will stop eating, choose a safe, shady corner, and then spit out the white silk to make silkworm pupa, and the young silkworms will hide in the silkworm pupae to develop and grow, and wait for half a month before breaking out of the pupae.

4. Adult stage

When the young silkworm emerges from the silkworm chrysalis, it enters the adult stage, the adult at this time is called the silkworm moth, has wings, and the whole body is gray-white, among which the larger size is the female silkworm open moth, the smaller body is the male silkworm moth, after the silkworm moth mates, the female silkworm moth will lay silkworm eggs again.
