Does silkworm have eyes, and where are the eyes of silkworms

Silkworms have eyes. There are a pair of tiny eyes on both sides of the silkworm's head, like two tiny grains of dust. Moreover, such eyes can only be distinguished on the head of the big silkworm, and the baby silkworm cannot see it at all.

The silkworm has six single eyes on each side of the silkworm. 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 silkworms:

Silkworms live on mulberry leaves, and after eating mulberry leaves, their bodies turn white, and after a while, they begin to peel. When the skin is peeled, you don't eat or move for about a day, which is called "dormancy".

After a peeling, it is the second instar larva, it sheds its skin once even if it increases one year old, 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 cocoons.

The eyes of silkworms grow on their heads.

The eyes of the silkworm baby are black-brown single eyes, with 6 on the left and 6 on the left. Five of the monocular are arranged in an arc, and the sixth monocular is the smallest, located in the center of the inner arc, and can only be seen with the help of tools such as a World Bank magnifying glass. Don't look at its eyes, but the silkworm's eyesight is very poor, and it can only roughly feel the intensity and direction of the light.

When the silkworm feathers into a silkworm moth, its eyes become compound eyes.

Eyes can only be called eyes if they have pupils like us and have white eyes. The silkworm's "eye trouser branch" can only be called "eye", but it is just some photoreceptor cells of the tong antler, and the "front wheel compound eye" is the eye of a fly or something. The eyesight is very good, but the eyes of the silkworm only sensitize light, and there is basically no visual effect, and the silkworm is on the mulberry leaf as soon as it hatches, and it is good to open the mouth to eat!

The caudal foot functions in the same way as the gastropod, crawling and immobilizing.

The living habits of silkworms

Silkworm babies are oligophagous insects, in addition to eating mulberry leaves, they can also eat leaves, elm leaves, grape leaves, onions, dandelions and lettuce leaves, etc., but eating these mortality will increase. The necessary nutrients for silkworms include proteins, carbohydrates, lipids, vitamins, inorganic salts, and water. Mulberry leaves are the most suitable natural food for silkworms.

After cannibalizing mulberry hu back sensitization, the larvae grow rapidly, under suitable temperature conditions, a silkworm from hatching to silking cocoon, about 6-9 days to molt once, a total of about 24-32 days, about 20-30g of mulberry leaves (dry matter, generally after four times of sleep and molting, to the extreme growth, the weight increases by about 10,000 times. Silk cocoon is an instinct of mulberry silkworms to adapt to the environment and survive.

Summary. Dear, I'm glad to answer for you: what is the function of the silkworm's prosthetic eye? The effect of the silkworm's false eye is as follows: The silkworm has eyes, which are single eyes, and have six eyes.

The eyes of the silkworm are monocular, not the eyes in the real sense, it only has the effect of light sensitivity, and cannot see the objects in front of it, and the silkworm relies on the sense of smell and touch to judge the objects in front and the direction of progress.

Black dots can be seen on both sides of the silkworm's body, which represent the stomata and allow it to breathe, but this is not its eyes.

What is the function of the prosthetic eye of a silkworm.

Dear, I am a teacher, I am happy to answer for you, I need a little time, please wait a while.

Dear, I'm glad to answer for you: what is the function of the silkworm's prosthetic eye? The effect of the silkworm's false eye is as follows: The silkworm has eyes, which are single eyes, and have six eyes.

The eyes of the silkworm are monocular, not the eyes in the real sense, it only has a photosensitive effect, and can not see the object in front of it. Black dots can be seen on both sides of the silkworm's body, which represents the stomata and allows it to breathe, but this is not the eyes of the sedan chair.

The eyes of silkworm babies are divided into single and compound eyes, and it is not easy to see without filial piety tools such as microscopes. So, what does the baby rely on to find food, in fact, it depends on the "lower jaw and lip whiskers" under the mouthparts of the head, which is similar to the antennae of other insects.

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.
