Why do you want to take off all your skin?

In the middle of the summer, it is common to hear the chirping of cicadas over and over again in the trees, and this is also a way for them to attract the opposite sex to come and mate. The larva that knows it is the golden cicada, and in some places it is also called the monkey, the turtle, or the fork. The life of this animal goes through four stages: egg, larva, pupae and adult.

When you know that after mating, you will lay eggs on the branches. In the summer of the following year, the eggs hatch into larvae when they meet the right temperature. The process from larva to pupae takes four molts.

When the larvae hatch, they fall along with the branches, and then these larvae burrow into the ground in the nearby soil, where they feed on the sap from the roots. It usually takes 3, 5, 7, or even 17 years for it to emerge from the ground after hatching. In this process in the ground, it has to continue to grow and develop, gradually from small to large, and it has undergone four molts before it is fully developed.

So why does the golden cicada molt and go through shelling?

This is because cicadas, like most insects, do not have a skeletal system, and the shell of their body functions as a skeleton. But this shell will not grow too much, so when the golden cicada grows up, this shell will limit its growth, that is, the shell can no longer hold it, so it needs to be replaced with a new shell, and molting is the way for them to change to "new clothes". At a certain time, the known larvae will molt once, and when they crawl out of the ground, they will carry out the last shelling, and only the golden cicada will have the ability to fly.

After four molts, when fully developed, the cicada will choose to emerge from the ground in the evening around the summer solstice, or after dark. Once out of the ground, they will choose the nearest tree, climb up along the trunk, and when they reach a certain height, they will fix their bodies, do not move, and then begin to "shell", generally the shelling of cicadas is concentrated between 9 and 10 o'clock in the evening, and the rest of the time is relatively less.

The golden cicada shelling is actually very interesting, it starts from the head, initially there is a crack in the head, and then the mouth gets bigger and bigger, and then the body slowly crawls out of this opening. The whole hulling process lasts about an hour or so. When the golden cicada crawls out of it, it will leave a layer of golden cicada shell.

The golden cicada that has successfully shed its shell has wings, but its body is still very soft at this time, and its wings are also green, and it cannot fly. After about 1 hour, the body slowly turns black, and I also have the ability to fly.

For the golden cicada, no matter that molt is a very painful experience, if the molt fails, it also means death. Some golden cicadas in the ground are unsuccessful in molting, and when they encounter suitable conditions, they will grow into "golden cicada flowers". And the golden cicada that crawls out of the ground, if it also fails to molt, it will not be able to feather and become a knowledge, and can only be eaten by natural enemies.

Of course, now for the golden cicada, the biggest world is human beings.

Because for the cicada to grow, it must shed its skin several times before it can mature.

The cicada chrysalis cannot be placed on a horizontal plane, cicada molting requires a vertical environment, you can put the cicada on a screen, turn off the lights and do not disturb it.

Put it in the shade, you can't use water, and you will die.

It's too dry, just spray it with some water.

Because cicadas are arthropods, their genes and growth patterns are destined to shed their skin over a certain period of time. The body of the cicada is composed of shell and flesh, once the bone shell grows and forms, it can no longer grow, so at this time, if it wants to continue to grow and develop, it must take off the shell, leaving enough space for the body to continue to develop and grow, because only in this way can a larger new ** be formed, we all know that in our nature, there are many sayings about wild animals.

It starts with a caterpillar and then slowly evolves into a cicada, and it has to go through molting, and it is also because it has to go through metamorphosis, so it can grow into a silkworm and have its own wings.

When the weather is warmer, the larvae will live on the sap from the roots of the tree, and when the larvae grow up, they will climb up the branches of the tree, and then they will pupate and slowly grow their wings. The reason why silkworms must molt is that there is a big difference between their juvenile state and adult state, and the skin of these insects is their own protective layer, so they must shed the outer skin before they can grow up.

First of all, the cicada is an arthropod, and it is developed from silkworm ants, and the cicada needs to shed its skin 4 times in the process of development, so that it can make its bones grow and develop again, because this animal is originally a body structure with bones and flesh, and the external bones have no way to continue to grow.

The growth of cicadas is mainly through the replacement of old shells with new ones, and the continuous growth and development of growth. Because cicadas need to go through the metamorphosis stage, they need to go through 4 molts before they can grow and develop.

They go through molting and go through it four times in their lives, at first they are eggs, and then they grow up slowly, because they are arthropods, so they need to molt.

The cicada is a very special animal in nature, and the cicada sheds its skin for metabolism. Cicadas are also a beneficial insect because they eat pests such as mosquitoes.

Replace your old shell and grow it. It is because of this that he can allow himself to live longer and grow up.

Not only cicadas, but all arthropods will molt, because the body of an arthropod is a structure of flesh and bones, and once its exoskeleton is formed, it cannot regenerate, so when the exoskeleton cannot accommodate its body, it will molt because it has to grow.

Because it restricts the development of cicadas.

This skin actually is.

The exoskeleton plays a role in protecting, supporting and preventing the loss of water in the body, the exoskeleton can not grow larger with the growth of the body, when the insect gradually grows, the exoskeleton will limit the growth of the insect, because the phenomenon of the insect shedding the exoskeleton during the growth process is the molting phenomenon.

Reason for cicada peeling: There is a relatively hard layer of skin on the surface of the cicada's body, which can prevent the outflow of substances in the body and prevent the invasion of harmful substances from the outside world. In this way, it is very detrimental to the growth of cicada larvae, and it restricts the growth of the young cicada's body.

For the growth of cicada larvae. So shell often.

Cicadas, hemiptera cicadas, live in temperate to tropical regions of the world (about 2,000 species of cicadas have been recorded). Some species found in desert areas will expel excess water from the tergum when the body temperature is too hot, which will cool and dissipate heat. The cicada has two pairs of membranous wings, the shape is basically the same, the head of the eggplant is broad and short, with a distinctly prominent frontal lip base; Visual acuity is quite good, the compound eyes are not large, located on both sides of the head and widely separated, and there are 3 monoculars.
