Male cicadas are the only insects to have an organ solely dedicated to the production of sounds. It consists of two curved plates, the cymbals, located at the bottom of the abdomen and connected by a powerful V-shaped muscle. The plates are deformed by the action of the cymbalic muscle, which can be stretched 300 to 900 times per second. This distorting vibration of the cymbals - which is therefore not a song per se - is called cymbalization. It is amplified by a resonance box that occupies more than half of the hollow abdomen of males.
