In summer, when soul singers know about it, they will sing heartily. Do you know why it is called?

Find a spouse and reproduce. Because Zhi Zhi's life is short, Zhi Zhi has been calling for a spouse. Only the male can bark, but the female can't. And I know that the call will also be affected by the weather. The hotter the weather, the louder it is. I will call when I am afraid. Knowing that I can only live for about a month, I will keep screaming in order to reproduce. Adult cicadas have a short life span. In order to find a mate to reproduce in a limited time, the male cicada must try his best to win the favor of the female cicada, and then end his life after mating.

Cicadas that disturb people's lucid dreams are all male cicadas with intact vocal organs, while female cicadas do not sing because of underdeveloped vocal organs. The abdomen of a male cicada is like a drum. When it vibrates, it makes a sound. Its vocal muscles can expand and contract about 10000 times per second, and the space between eyelid and eardrum is empty. It can also play the role of vibration, so the cicada's cry is particularly loud. The female cicada will know roughly whether the owner of the sound is healthy or not and whether she has the ability to reproduce by singing. After some consideration, females will fly to the boy they are looking for and finish mating.

Cicadas can sing loudly, but instead of using their mouths or throats, they use a pair of cymbals-like "musical instruments" in their empty bellies behind their wings. Its chirp is the current output by the body nerve, which stimulates the tympanic membrane located in the cavity. This is caused by the tone muscles of the upper body vibrating at a frequency of 10000 times per second. Cicada singing is its way of courtship. All cicadas can sing, and all females are dumb.
