By reading this article, we know how cicadas make sounds. It turns out that cicadas don't make sounds with their mouths, but there are two large semicircular covers under their breasts near their thighs. There is a cavity under each cover, and a small hole outside the cavity is called a sound window. Another cavity communicating with the acoustic window is called the acoustic chamber.

Just like the cymbals we use, they vibrate back and forth to produce sound. I don't know if this is a coincidence or if humans borrowed the vocal organs of cicadas to make musical instruments.

By observing the biological structure and living habits of animals, human beings have invented many tools that are beneficial to the progress of human society-airplanes, submarines, etc. How great and clever we humans are!

Creative background:

Cicada is an article by French writer Fabres, which comes from the work Insect. This paper describes the characteristics of cicadas from two aspects: the crypt and the egg.

This work is an insect biology book, which summarizes the species, characteristics, habits and mating habits of insects, records the real life of insects, expresses the spirituality of insects in struggle for existence, and also records Fabers' motivation, life ambition, knowledge background and living conditions of being obsessed with insect research.

The author combines the colorful life of insects with his own life feelings, treats insects with a human attitude, and reveals his respect and love for life between the lines.
