In the summer, cicadas are often heard, but why is this happening?

This phenomenon occurs because cicadas only appear in summer, and cicadas like to chirp.

Because cicadas need to mate in the summer, they can only attract the opposite sex by making sounds.

In the summer, cicadas attract males through their sounds, so that they can reproduce.

In the summer, the animal breeds more and is more likely to appear, especially in hot weather.

Because cicadas are sensitive to weather changes, they will keep calling due to weather changes.

<> hometown in the countryside, the newly unearthed cicadas are called "knowing monkeys, and after shedding their shells, they are called "knowing them". Cicadas come out of the soil at night, climb up the trees nearby, and then shed their shells and become "knowing". There is an idiom "golden cicada."

Hulling", which is the process. The best time to look for the "knowing monkey" is at night, and once it is out of its shell and becomes "knowing it", it will soon be full of wings and fly away. It's hard to catch it again.

Of course I played, this is our 80's memory, in our hometown called this little thing "know the leaves", whenever they enter the summer they come out, chirping in the trees non-stop, at this time we love to be naughty to find them, catch to play, the shell of the shell is a taste of medicinal materials, we have a Chinese medicine uncle in the neighborhood, it will often pick a lot of back to dry as Chinese herbal medicine.

A monkey needs to go through a lot of hardships from egg to adult. First of all, we know that after laying eggs, as the branches fall to the ground, the hatched small larvae have to burrow into the ground, going deep into the ground with tens of centimeters shallow and as deep as several meters, in the process looking for the roots of the tree to suck the sap. The process itself is very difficult and requires extreme stamina.

Edible dura. The turtle does not bring any physical discomfort to people, on the other hand, there are many people who like to eat Dura turtle, after all, after frying, whether it is color, flavor or nutritional supplements, it is very good, so Dura turtle has gradually become a delicacy on the farmer's table, especially the children in the countryside like to eat it very much.

The monkey matures in three to five years, and becomes known to only have a little more than half a month of life. Know, know, it should be the saddest tune in the world. A few years are unknown, and life is not long after being known.

Scholars named it the golden cicada, because it called out the voices of many readers, ten years of hard study for fame, once the marquis was light. Look at the bird and hide the rabbit and the dead dog cooking, Lingyunzhi, turned into a confused sound.

In fact, it's not that ants don't eat monkeys, but they rarely eat them. Because the monkey lives underground all year round, although ants can burrow, the ant's burrowing is particularly shallow, and it takes thousands of ants to complete. Therefore, the monkey is basically invincible underground, and no creature can kill it.

Anyone who has watched "Animal World" knows very well that most animals call to attract the opposite sex to mate. And the male's call is also to attract the female to know, so that they can reproduce. Often, once the mating is successful, the male's mission is completed, and then he dies quietly.

Females, on the other hand, do not die until their eggs are laid. As for why the hotter it is in the summer, the happier it is, it is because in the hot weather, the cicadas are more active.

Because the cicadas lying on the trees in summer are courting, they are generally heard in the summer, and this is because it is the season of production again, so the male cicadas will attract the female cicadas by chirping.

The reason why the cicadas in summer always keep calling is because the cicadas are attracting the arrival of the opposite sex and want to mate.

Because adult cicadas have a short lifespan, in order to find a mate in this limited time, they have to chirp as hard as they can to gain the favor of the female, and then end their lives after mating.

In fact, they are not calling but singing, because the life of cicadas is very short, there is only one summer, so they cherish it very much, which leads to them calling all the time.

Because they are attracting the opposite sex and are ready to work hard for the next generation, they make the opposite sex fly over by making a sound.

This is because they are there to attract the attention of the opposite sex. Thus mating takes place.

The sound of the cicada in summer can be described as "knowing", "squeaking" or "chirping", but in fact, the sound of the cicada can also be described as "ticking", there is a kind of cicada, it only calls when dusk comes, this is what we often call the evening cicada, the voice of this cicada is more emotional, and the call is the sound of "ticking", which is very good

The cicada's voice is not monotonous, it is like the sound of a bird, and the cicada has a cymbal-like instrument in the cavity behind its wings, so it can make a sound, and it can take turns singing in a variety of different tones.

The principle of cicada vocalization

Not all cicadas will call, only the male cicada will call, the male cicada has a vocalizer in the abdomen that can make a loud sound continuously, and the female cicada can not make a sound although it also has a vocalizer in the abdomen.

The cicada's articulator is in the abdominal muscles, like a large drum covered with a layer of eardrum, and the eardrum is vibrated to produce sound, because the cover plate and the eardrum are empty, which can play a resonant role, so its sound is particularly loud.

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.

Because the reason why the cicada will call in summer is in courtship refers to the rental year, all through their own chirping to attract the attention of the opposite sex, to achieve the purpose of courtship, especially in the sunny noon, the cicada's call is the loudest, if there is a storm or rain only open time, the cicada will not be able to chirp.
