How many days do cicadas live? How long can cicadas live?

Cicadas do not have a saying that they can only live for seven days. The longest three lifespans of cicadas are about 60 to 70 days, which is still relatively long. The life cycle of French cicadas is mostly 4 years, while in North America it is 3 to 7 years, nearly half of which are 5 years, and a few spend 8 to 9 years.

Biologists generally agree that cicadas are the longest-lived insects in the world. After the cicada climbs from the ground to the tree to form a flying adult, it dies after completing the mating process with the opposite sex and reproducing offspring.

The habits of cicadasThe larvae of cicadas live in the soil, sucking the sap of plant roots, weakening the tree, causing the branches to die, and affecting the growth of the tree. The larvae of grasshoppers live in the soil all their lives. When it is about to be feathered, it burrows out of the ground surface at dusk and at night, climbs the cicada on the tree, and then grabs the bark of the tree to molt and feather.

Cicadas are mostly found in the tropics, inhabiting deserts, grasslands and forests. In addition to the species of the genera such as the three-dog cicada and the moth cicada that appear in midsummer every year, there are also periodic cicadas. The most well-known periodic cicadas are the 17-year-old cicada and the 13-year-old cicada.

According to biologists, cicadas have a lifespan of about 17-20 years.

The cicada spends most of its time in the soil, and after the last spring, it emerges from the soil, grows into an adult, sings passionately in the branches, and sings until the autumn wind blows, then it stops singing and dies silently and quietly.

Generally speaking, the call of cicadas, which is often heard in summer, grows underground for 10 years during the larval stageHowever, after being detached from the ground, because of the evolution of the mouth, it is said that energy can only be absorbed through dew drops and branches and leaves of trees, and because of this, after the successful transformation, the lifespan is very short, only three months, and in general, the lifespan of a person is not more than 11 years, which is due to the following reasons

1. Most of them hide underground only when they are larvae, and this process can be as long as 10 years. In fact, it is inconceivable to us that it takes a long time for materials to survive underground in kindergarten, and this time period is even more than 10 years, so it takes a long time for the larvae of Zen to break through the ground. <>

2. After the larvae break through the soil, their lifespan is very short, only a short summer, that is, three months long. We know that after the Zen matures, we can only live on the tree, and this lifespan is only three months, and it is incredible that most people can not tolerate the cold weather in the autumn, so it will lead to death, and the natural enemies of the cicada are also very numerous, so the lifespan of Zhizhi is also very short. <>

3. In general, the lifespan of Zhizhi can be as long as 11 years, but more than 10 years are spent underground, and only three months are discovered. What is very interesting is that the lifespan of the cicada, although it is said to be as long as 11 years, but almost 10 years are spent in the long underground survival, and only three months after it can get out of the ground, so the life of knowing is also tragic.

In the summer, we often hear the cry of Zhizhi, and it is known that it takes about 11 years from larva to adult, but it survives underground for almost ten years, and only three months after breaking the ground, it is the rest of its life, and this happens to be the most glorious moment of Zhizhi's life.

Different species of cicadas have different lifespans. Adults who usually regain sight after molting have a lifespan of about 15 days, and the shortest may be only three days. After the black knows the adult, its lifespan in the sun is only 45 to 60 days.

They are very weak in nature, and the number of eggs they lay is about 300 to 400, but the number of eggs that survive to adulthood is very small. <

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.

The larvae 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. Usually stay in the soil for a few years or even more than ten years, such as 3 years, 5 years, and 17 years, these numbers have one thing in common, they are all prime numbers.

Cicadas do not have a saying that they can only live for seven days, and the maximum lifespan of cicadas is about 60-70 days, which is still relatively long. 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.

The larvae of the cicada live in the soil, usually stay in the soil for several years or even more than ten years, such as 3 years, 5 years, and 17 years, when they are about to feather, they drill out of the soil surface at dusk and night, climb on the tree, and then grasp the bark and moult with the trace bark to feather.

There are many kinds of cicada rolling, and the life cycle of different species of cicadas is different, the so-called life cycle of cicadas, that is, the time it takes to complete a generation, generally ranges from 3 to 17 years.

The life cycle of the Chinese cicada is about 3 to 7 years, the life cycle of the French cicada is about 4 years, and the life cycle of the North American cicada is 13-17 years.

The life of a cicada is divided into three stages:

1. Larval land insects: live on the roots of trees, the long time can be about 17 years, and the short time is only 3 seasons.

2. Pupa: The larvae evolve into adults, which generally takes 2-3 days.

3. Adults: The lifespan of cicadas is relatively short, generally about 10 to 15 days.

The growth process of cicadas:

The mature larvae of cicadas emerge from the soil from late May to mid-to-late August, molt and emerge into adults, and the adult appearance is at its peak from mid-June to mid-July, and the end stage is in early October.

About 20 days after the adult emerges, the eggs are laid by the tail, and the eggs are laid in late June, and the adult eggs are at their peak from the end of June to the end of August, and the end of the eggs is from early September to early October, and the final period is in early November.

Cicadas can live for about 14 to 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. Female adults begin to lay eggs in late July, and the peak oviposition is in early to mid-August, when eggs are mostly laid on branches 4 to 5 mm thick. There are many kinds of cicadas, and the life cycle of different species is different, and its life cycle, which is to complete a generation, varies from about 3 to 17 years.

Cicada-related situation

Cicada is commonly known as the general name of 2,500 species of insects under the general family of cicadas, they are widely distributed in temperate and tropical regions around the world, and even cicadas exist in some deserts, and there are at least hundreds of species of cicadas in China. According to the obvious differences in body size and appearance, there are three common types of cicadas: black grasshoppers, cockroaches and crickets.

Among them, the black grasshopper cicada is distributed in the north and south of China, the whole body is black, and there are yellow or black lines on the wings, they are the main players of the summer cicada. The cockroach cricket is a genus of the cicada family Cockroach crickets, and their body size is significantly smaller than that of the black grasshopper, with an average body length of about centimeters.

In the north, the body color of the cockroach cricket is mainly black-brown, which is very close to the color of the bark, and the cry is relatively sharp and similar to the "squeak" sound. In some areas of the south, the body color of cockroaches is mainly green, but there is basically no big difference in sound.
