Know what is the metamorphosis? What is the metamorphosis process of a cicada?

I know that it is a cicada chrysalis metamorphosis!

Cicada pupae is a common insect in Northeast China, North China and other regions, and it is a known larvae.

How did you metamorphose, it's simple.

The metamorphosis process of the cicada is latent, molting, and turning into a cicada.

After laying cicada eggs, they will lie underground for several years, replenish themselves by sucking nutrients from tree roots, and slowly grow into cicada pupa. When the cicada pupa grows to the shell has obvious black lines, the cicada pupa at this time will run to the surface for shelling and transformation, and the cicada pupae in this process will mostly climb to the tree, usually the cicada chrysalis will climb out of the upper body first, and will stay in the tree for a period of time after completely climbing out, so that the wings become harder and firmer, which is conducive to flight.

Habits: The larvae of cicadas live in the soil and have a pair of strong digging forefeet. The sap of plant roots is sucked by the piercing and sucking mouthparts to weaken the tree, make the branches die, and affect the growth of the tree.

Cicadas usually stay in the soil for several years or even more than ten years, such as 3 years, 5 years, and 17 years, and these numbers have one thing in common, they are all prime numbers. This is because there are very few factors in prime numbers, and when they drill out of the soil, they can prevent them from drilling out with other cicadas and competing for territory and food.

When it is about to be feathered, it burrows out of the surface at dusk and at night, climbs on a tree, and then grabs the bark of the tree to molt and feather. When a black crack appears on the back of the cicada pupa, the molting process begins, the head comes out first, then the green body and wrinkled wings are revealed, and it stays for a moment to harden the wings and darken the color, and then it begins to take off.

After the cicada chrysalis grows up and molts, it is known and the monkey is known.

It is a nymph of a cicada, not a real pupa, the cicada is from the nymph stage, and the young cicadas will eventually crawl out of the soil and become cicadas after molting again and again. It does not experience the pupal stage, but some people will know the monkey or silkworm chrysalis.

They are all called cicada pupa. After the cicada chrysalis molts, it is known, and it is a different insect state that is known. Generally, some places will call silkworm chrysalis cicada chrysalis, and there is no distinction.

The silkworm pupa generally refers to the pupae that the silkworm turns into in the cocoon after spinning silk to make a cocoon. Silkworm pupae are not only delicious and nutritious, but also extremely valuable animal protein**, and are the raw materials for extracting a variety of chemicals.

The protein contained in silkworm pupae is easily hydrolyzed, and is similar to human protein, with a human absorption rate of about 90%. Therefore, silkworm pupae can not only supplement fat, protein and multivitamins, but also increase brain cell vitality and improve thinking ability. Silkworm pupae are rich in chitin.

Its extract is called chitosan.

In the United States, Japan and other places, it has been used as a new food additive. Silkworm pupa is suitable for boiling, frying, dry stir-frying, stir-frying and other cooking methods, common dishes are crispy silkworm pupae, boiled silkworm pupae, clear brine silkworm pupa and cumin silkworm pupae. Either way, it must be fully heated before eating, and boiled before other cooking.

Before knowing that there was no metamorphosis, the larva called the cicada, the scientific name is the cicada pupa.

Before the cicada sheds its skin, it belongs to the larval period, and the title on the general textbook is the larva of the cicada, but the folk saying is called the monkey or the cicada monkey. It has a body length of about 4 cm to cm and the color of the base of its wings is dark brown.

Usually cicada larvae inhabit the soil and live by sucking the sap from tree roots, which we usually do not see. The ancients had never seen how the larvae of cicadas reached the ground, so they believed that cicadas were transformed from the larvae of dung beetles or beetles. The legend of "dung beetles turning into cicadas" was widely spread in ancient times, and even the "Treatise on Balance", which is known for its rigor, also said:

The grub turns into reproduction, and the rebreeding turns into a cicada. "Grubs" are beetle larvae, and "ask for rebirth" is a cicada that has just been drilled.

Actually, cicada larvae hatch from eggs laid on branches by female cicadas. The deceptively simple process of moving them from branch to ground and from ground to branch takes them almost a lifetime.

The growth process of cicadas:

In June and July of each year, they will turn from pupae to adults and then lay eggs in just a few days, starting from the eggs, through the process of the nymphs living in the ground, until the last time they shed their shells and become adults, and they are loud in the trees, usually one to two years.

Among the cicadas, their larvae are also called "nymphs", their male cicadas will make sounds to attract female cicadas to mate with them, and they use their sharp oviposition tubes to lay eggs close to the tree, and the larvae will not hatch until the next year, and then live in the soil for a few years or even more than ten years before breaking through the soil.

In a long life, they have to go through many shellings, and the next shelling is also when it becomes an adult, and when it becomes an adult, it will make a sound, and the sound made by the male cicada is at a high frequency of hundreds of times per second, constantly moving the two tympanic membranes located in the abdomen, to make a sharp and loud sound. This sound helps the female cicada determine the appropriate position of the male cicada for mating.

Because it is known to be an insect without a skeletal system, it relies on its hard skin shell to protect the substances in the body from outflow and prevent injury, but when it develops to a certain stage when the body gradually grows, the skin on the body surface can not grow up, at this time, it is necessary to shed the outer skin shell, so that the body can grow freely, so when it reaches a certain age, it will molt.

In fact, most of the lives of the people who have experienced 4 molts are spent in the soil, and they will stay in the soil for several years or even more than ten years, and finally they can only live for about one to two months after becoming an adult. The whole process is composed of four stages: egg, larva, pupa and adult, in the next three stages due to the need to grow larger, it will go through 4 molts, and the last molt will climb from the soil to the tree, and complete the final metamorphosis on the tree, the process is very magical, just like a caterpillar.

It's like a beautiful butterfly, but I know that it's not as bright and beautiful as a butterfly.

After several years of dark life in the ground, the larvae will climb on trees, crops or blades of grass in rainy or wet weather, generally around 9 to 10 o'clock at night, avoiding various predators, and then immobilize their bodies and begin to molt. Before the molt, it is known as the monkey.

After molting, it will become an adult, and then it will be able to soar into the sky with a blockbuster.

After the molting process is learned, the monkey will climb the branch, and will hook the bark tightly with its paws to fix it on the tree, and then remain motionless as if asleep. With the passage of time, the molting action of Zhizhi begins, first breaking open a hole in the head or back of Zhizhi, and then slowly breaking free from this opening, this process takes about an hour, and the shell remains in place after Xinzhi climbs out. At this time, Zhizhi is still very tender, the body is a little white, the skin shell of the body is very soft, and the wings are wrinkled, but after an hour of rapid development, the body will turn black, and the wings can also be stretched out to have the ability to fly, and the knowledge will be able to live a soaring life.

One night, my father caught a monkey for me, so I put it in a box and cut a small hole in the top of the box to make it breathable. It is dark brown all over its body, with a hard shell on the outside.

The mother said, "If the monkey wants to become a monkey, it has to withdraw its hard shell and grow wings, and it will change tonight." "I wanted to see it turn into fluid, but I fell asleep.

The next morning I didn't open my eyes to see it, it really changed, its body became bigger, and it also grew wings, but the wings were not complete, next to it was his empty shell, I took a closer look, there was a crack in the shell, my mother said that it was drilled out of this mouth, but unfortunately I didn't see it, my mother used her mobile phone to search for the ** of the transformation, I saw that the transformation has been shaking and struggling, I think he must be in pain, but in order to be able to fly freely and sing happily, it is not afraid of pain, it is really amazing!

I gently lowered it to the small tree downstairs, hoping that it would have wings and fly freely.
