How long is the life cycle of the cicada in summer?

How long do cicadas live.

Cicadas don't actually live for seven days, and their maximum lifespan can reach about 70 days. The cicada is considered to be the longest-lived insect in the world, and the life cycle of the cicada varies from place to place, for example, the life cycle of the French cicada is generally four years, while the life cycle of the cicada in North America is up to 17 years.

Cicadas in China generally live for 3 to 7 years, and about half of them have a life cycle of 5 years. As for why cicadas are only seen in summer, it is because they spend most of their life cycle in the soil before breaking through the soil and metamorphosing into cicadas.

The cicadas will go through all the development processes in the ground, and when the time is up, they will break through the soil and mate to reproduce the next generation, and when the mating is complete, the male will die, and the female will also die after laying her eggs in the soil. Therefore, cicadas die soon after they are unearthed, which is why we feel that the life of cicadas is very short.

Why are cicadas called.

Cicadas usually chirp incessantly during the day, which is for courtship. In the summer, many cicadas will call together and stop together, a phenomenon called "chorus". Because only the male cicada's articulatory organs are fully developed, only the male cicada can chirp, and the female cicada cannot chirp because the articulatory organs are not fully developed.

Therefore, the male cicadas attract the female cicadas to mate through the "chorus".

As we mentioned earlier, after mating, the male cicadas die, and even the female dies soon after laying eggs. Therefore, these cicada chirpings that make people feel irritated in summer are actually the summer swan song of cicadas, and they are also the sounds of nature.

Different species of cicadas have different life cycles.

French cicadas mostly have a life cycle of 4 years, while North America has cicadas that live up to 17 years. Most of the Chinese cicadas live for 3 to 7 years, nearly half of them are 5 years, and a few can survive 8 to 9 years.

Biologists generally agree that cicadas are the longest-lived insects in the world.

The life of the cicada is spent like this: the conceived female cicada uses the ovipositor at the tail to punch holes in the branches, pierce the xylem, and reach the heart of the medulla, and each orifice lays several eggs, and there are dozens of small holes, and the total number of eggs is generally 300 to 400, up to 600. Like other weak creatures in nature, most of them do not survive adulthood.

After the eggs hatch on their own, the larvae burrow small holes, molt for the first time on the branches, and after a few hours, the epidermis keratinizes and hardens, falls to the ground, digs with its front paws, burrows into the mud, spends long years in the dark, and survives and grows by sucking the sap from the roots. The vast majority of adult cicadas that burrow out of the ground and regain sight after molting have a survival period of less than half a month, the shortest is only a pitiful 3 days, and the longest black grasshopper adult has only 45 to 60 days of survival in the sun.

The lifespan of cicadas is about 14-60 days. At the end of June, the larvae of the cicadas begin to emerge into adults, and the newly fledged cicadas are green and have a maximum lifespan of about 60 days. In late July, the female adults begin to lay eggs, and the peak oviposition is in early and mid-August, and the eggs are mostly laid on branches with a thickness of 4 to 5 mm.

It is found in temperate and tropical regions, inhabiting deserts, grasslands and forests. In addition to the species of the genus Moth Cicada that appear in midsummer every year, there are also periodic cicadas in the limbs of the acre. The most famous periodic cicadas are the seventeen-year cicada and the thirteen-year-old cicada, also known as the prime cicada, because the life cycle is prime, so it will not encounter the natural enemies encountered in the previous generation.

Periodically, cicadas occur once in a certain area at certain intervals, when dozens to hundreds of black-brown cicada larvae emerge from the soil and emerge together, which is very spectacular. Some species are easier to identify by their vocalization, behavior, and morphology.

The cicada is known as the singer of nature in the state of Okuanmono, naturally because the cicada will come out of the soil every summer, climb the tree and make a non-stop sound, as if singing, which is why the cicada is called the singer of nature. Moreover, the cicada song has been loved by many literati and writers since ancient times, and has been written into many masterpieces, so the cicada song is indeed a very beautiful sound, which makes people reverie infinitely. To my ears, the chirping of cicadas is quite a kind of noise, which makes it impossible to sleep peacefully in the scorching summer heat.

The cicada chirping is actually the sound of courtshipThe life of a cicada is actually very long, but when we see a cicada, the cicada is actually not far from the end of its life, because the cicada only needs to come out of the soil to complete the feathering and make a cicada song. In fact, the life of the cicada is only about two to three months, because the cicada makes a cicada song, which is a signal that the cicada is looking for a mate to reproduce. Moreover, the male cicada with a louder cicada song can be favored by the female cicada, because it means that the male cicada is strong and can breed better offspring, so the female cicada will follow the sound to find the male cicada and mate with it, completing the task of reproducing offspring.

Cicadas spend most of their lives in the soil, and cicadas will enter the soil during the larval stage and live in the soil for as little as three years and as many as ten years, but this depends on the species of cicada and the time they live in the soil is also different. However, the time that cicadas live after becoming adults is far from being comparable to the time cicadas live in the soil. Therefore, although the cicada makes an irritating cry after coming out of the soil, this moment is the most brilliant and glorious moment in the cicada's life.

Because the cicadas used to spend their time in the dark underground.

Moreover, the cicada chrysalis shed by the cicada can also be used in traditional Chinese medicine, which is a very good medicinal material. In order to be ashamed, they suck the branches and leaves of trees, but they do not let the trees die and affect the growth of trees. So the cicada is not a pest.

I hope you don't kill the cicadas as soon as they see them. And in the summer, if you don't hear the cicadas, you will feel bored. Although the chirping of cicadas can be extra noisy when people are upset.

But if there were no cicadas, then summer would not have the taste of summer.

The periodic cicada is the genus name of a class of cicadas in North America that has a life cycle of thirteen or seventeen years, also known as the seventeen-year cicada or thirteen-year cicada. Once hatched, the larvae burrow into the ground and spend most of their lives underground, surviving on the sap from tree roots.

Generally speaking, the life cycle of cicadas is 2 to 5 years, more than 13 years, the longest is 17 years, and it can take up to 17 years to complete a life cycle.
