Why do cicadas call at night and when do cicadas not call

According to scientists, the chirping of cicadas is related to the weather. In summer, the cicadas call about 2 hours before the rain turns clear, but when the sunny day turns cloudy, the cicadas do not call. And when the weather continues to be fine, the cicadas also chirp.

This is because before the rain, its pronunciation film is damp and does not vibrate effectively. On the contrary, the weather improves, the air is dry, and the film vibrates vigorously. Generally speaking, when there is dew or heavy rain in the early morning, the cicada song will stop and the cicada singing will be suspended.

Therefore, there is a poem of "the guest goes to the flat threshold, and the cicada is full of branches" (Li Shangyin's "Falling Flowers").

So it is possible to call it during the day and at night.

The night call is caused by the cicada being blind or having an endocrine disorder. Absolutely no nonsense.

No, it's even worse during the day!

Haven't heard of it yet, it's generally a summer afternoon.

The cicada call is only related to the temperature (the temperature is greater than 30 degrees, the cicada will chirp and court), usually.

The conflict between the "night cicada" and the traditional impression that "cicadas don't call at night" is related to the region, and in some places the temperature will drop to below 30 degrees at night and higher than 30 degrees during the day, so it gives people the illusion that cicadas do not call at night. In fact, cicadas chirp at night and during the day.

Cicada chirping has nothing to do with light; If the temperature is greater than 30, there will be courtship; Courtship chirps are carried out only in trees; Stop immediately in case of danger.

Why is it not the question of when the cicadas are calling? In the summer, cicadas chirp due to lack of water.

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.

Cicadas are a sign of summer, and during this season they chirp in the sun, making people wonder when the cicadas start calling. In fact, the timing of cicadas starting to call is influenced by many factors.

Temperature. Cicadas need warm temperatures to start chirping loudly. Summer temperatures are generally between 28 and 34, and when the temperature reaches 28, the cicadas start calling. If the weather is too cold, the cicadas will become lazy and will not be willing to call.

Time. Different cicada species have different call times. Some cicadas start chirping at 5 a.m., while others don't start chirping until after 12 noon. Most cicadas call during the day, but there are also cicadas that call at night, such as the shorthorn cicada.

Growth cycle. The growth cycle of cicadas is about two years, and the time when cicadas start chirping is also related to this cycle. Generally, cicadas will start chirping in the first few days of their adult life.

This is because they need to find a mate and reproduce offspring in a short period of time to complete the task of passing on the lineage.

Weather conditions. In addition to the temperature, cicadas also need suitable weather conditions to start chirping. On hot and humid days, the cicadas' chirping will be clearer and louder. And on rainy days, cicadas will stop calling because the rain will affect their calls and reproduction.

Conclusion. In general, the timing of a cicada's call is affected by many factors, including temperature, time, growth cycle, and weather conditions. But usually, the cicadas start chirping during the summer months to give people a sense of the summer vibes.

Whether in the suburbs or in the city, when you hear the call of cicadas, you know that summer has arrived.

Cicadas chirp at night, mostly due to light pollution in the city or other reasons, and can stay until midnight.

The male cicada will chirp, its articulator in the abdominal muscles, like a large drum covered with a layer of eardrum, the eardrum is vibrated and produces sound, because the sound muscle can be retracted about 10,000 times per second, the cover plate and the tympanic membrane is empty, can play a role in resonance, so its song is particularly loud. And can take turns to sing passionately in a variety of different tones.

The cicada calls in order to reproduce offspring.

To reproduce offspring, you must first find a mate. But compared to a forest or a park, the cicada is so small that in order to attract the attention of the females, the lads have to keep singing to introduce themselves and indicate their position.

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