Why do cicadas only chirp for one summer, and why do cicadas keep calling in summer?

Only male cicadas will call (females may also call, but we can't hear them, generally what they hear are males), they call for courtship, summer is their mating period, the louder it is, the easier it is to succeed in courtship, and male cicadas will die after mating. As for why it's so loud, it's a matter of their body structure.

He'd die, and he'd been underground for most of his life.

Calling is not its purpose, the purpose is to reproduce.

Why do you say that its life underground makes no sense.

Why does it have the meaning you say it is alive for?

Nature is arranged in this way, and man is only a small part of nature, and nature does not operate according to man's consciousness and human standards.

Is it true that a person lives in vain before he becomes famous, and if he is unknown all his life, he should not live.

Zen has lived in the earth for 17 years, just to come out or for a summer, no matter what fate is, to live well.

Only male cicadas call, they call for courtship, summer is their mating period, the louder it is, the easier it is to succeed in courtship, and male cicadas will die after mating. As for why it's so loud, it's a matter of their body structure.

The cicada's pupae spend the first two or three years of its life underground, perhaps for a longer period of time. The cicada is a male cicada, its articulator is at the base of the abdomen, like a large drum covered with a layer of eardrum, the eardrum is vibrated and makes sound, because the sound muscle can be expanded and contracted about 10,000 times per second, the cover plate and the eardrum is empty, can play a role in resonance, so its song is particularly loud.

The larvae of cicadas live in the soil all their lives. When it is about to be feathered, it burrows into the surface of the earth at dusk and night, climbs on a tree, and molts and feathers. At the end of June, the larvae begin to emerge into adults, with a maximum lifespan of about 60 to 70 days.

In late July, the female adults begin to lay eggs, and the eggs are at their peak in early and mid-August, and the eggs hatched in mid-June of the following year. After hatching, the larvae fall from the branches to the ground and burrow into the soil. The larvae live in the soil for several years and molt a total of 5 times.

When spring is warm, the larvae move upwards to suck the sap of plant roots, and when autumn turns to winter, they go deep into the soil to avoid the cold.

Has a unique body structure.

In the hot summer, hearing "knowing that you are screaming about summer" is annoying, but it is also indispensable, but do you know these animals? Why do cicadas keep calling in summer?

The burrowing time of cicadas in China is 3 to 7 years, the cicadas in France are 4 years, and the cicadas in North America are 17 years old. The larvae have been dormant for seventeen years and emerge from the ground. Every summer, 30 billion cicadas appear, and the climatic conditions are adapted, reaching 1.5 million cicadas per acre of land, the largest insect colony.

Most insects do not live for more than a year, and the seventeen-year-old cicada is the longest time to surpass the insects, and it is a veritable longevity champion among insects.

The red-eyed cicada lives in the United States, and there are also red-eyed cicadas in China: Ji Cicada, who feels that the sound is like chanting, so Ji Cicada is called a red-eyed Taoist.

The horned cicada is very different, like a deer antler, like a cow's horn, like a rhinoceros horn, like a one-horned fairy horn; Some personal characteristics.

The horn is a deformation produced by the dorsal plate of the prothorax, which is used to simulate the action of the thorns of the plant, and is not used for fighting, and both females and males have horns.

When it comes to summer, the cicadas can't stop calling, do you know why? Come and increase knowledge together.

Because summer is the season for cicadas to mate, male cicadas attract female cicadas to mate through cicada chirping, and male cicadas will die after mating, and their lives are very short, so they chirp desperately to achieve mating.

Because cicadas only crawl out of the ground to reproduce in summer, and this is the instinct of cicadas, cicadas will keep calling in summer.

The main reason why cicadas chirp in summer is that cicadas can survive for a very short time in adulthood, and only by desperately chirping to attract female cicadas to mate with them can they ensure that the cicada's offspring continue to reproduce and avoid genocide.

It is the male cicada that is calling, but it is actually seeking to mate, attracting the female cicada to mate, and after mating, she will die. And it doesn't bark at night, because there is no sunlight, and the cicadas are not active.

Reason: Only males chirp in adult cicadas, attracting females to mate, and most cicadas die after mating, so cicadas only chirp in summer.

The cicadas that can chirp are all male cicadas with complete articulators, and female cicadas do not chirp because their articulators are underdeveloped. The articulator on the abdomen of the male cicada resembles a drum and makes a sound when it is shaken. Its vocal muscles can stretch and contract about 10,000 times per second, and the gap between the cover plate and the eardrum is empty, which can also play a resonant role, so the cicada's call is particularly loud.

The female cicadas will roughly understand whether the owner of the sound is healthy or not, whether they have the ability to reproduce, and after some consideration, the female cicadas will fly to the young man in their picture to complete the mating.

In summer, there is no cicada chirping at night, because the activity of cicadas decreases after the temperature and light intensity drop, so it is not easy to hear cicadas at night. State faction.

Summer is the breeding season for cicadas1. Summer is the courtship time of cicadas, and they keep chirping to show their majesty and win the attention of the opposite sex.

2. The cicada is a kind of Kunshaochang liquid insect that lives in the temperate zone to the tropical region of the world, and summer is the breeding season of the cicada, and the call of the cicada is one of the most important ways for them to court. Cicadas vibrate with their chest muscles to make a call that can be heard throughout the forest in search of suitable breeding targets. The sound of cicadas varies from high to low and at different frequencies, which can also distinguish the species, sex and age of cicadas.

In addition to courtship, the call of the cicada can also scare off predators. Since cicadas are herbivorous insects, they are rich in nutrients and attract many carnivores. In order to avoid ** food, the cicadas will keep calling, and the deafening sound can play a good deterrent role, so that natural enemies dare not approach.

Because the cicada is a summer animal, it will only appear in the summer when it is hot, and the cicada has a very short lifespan, and it will hide in the soil in winter.

The female lays her eggs on a branch, and when the young cicadas hatch, they immediately climb down, burrowing all the way into the soil, where they begin their long underground sail life. The young cicadas have to stay underground for so long, firstly, because they are developing slowly, and secondly, they have to wait for the right time to break through the ground. Different species of cicadas will choose their first after birth.

Three, five, seven, ten.

1. Unearthed after the 13th or 17th year of orange high.

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 drilling out of the soil, they can prevent them from burning and hailizing together with other cicadas, competing for territory and food.

In the summer, the lead may be irritated by the noisy cicadas. The sound of cicadas in summer is actually a courtship signal of cicadas, just like the peacock opening the screen.

The cicada's good life course is very long, but most of the time is the larval stage, the cicadas in this period are buried in the ground, they are buried in the ground for several years or even more than ten years, before they break through the ground, and after breaking the ground, they can only live for one summer. In order to complete the task of reproducing offspring in this summer, the cicadas must first find their mates to chirp as their courtship signals. Adult cicadas have a short lifespan, and in order to find a mate in a limited amount of time, they have to chirp as hard as they can to gain the favor of the female, and then end their lives after mating.

Female cicadas do not chirp because their articulators are underdeveloped. The articulator on the abdomen of the male cicada is very similar to a drum, and when it is shaken, it will make a sound, and the noisy cicada sound we hear is made by a male cicada. When they can't be heard, their life is exhausted.
