The Buzzing of Cicadas
How Do Cicadas Make Their Sound?
The male cicada is responsible for the loud, shrill droning noise that is characteristic of these insects. This noise, which is used to attract females, is produced by vibrating two membranes on the cicada's abdomen. The membranes are connected to muscles that cause them to vibrate rapidly, producing the characteristic buzzing sound. The sound can be amplified by the cicada's large, hollow abdomen, which acts as a resonator.
The Significance of the Cicada's Song
The cicada's song is not only a mating call, but it also serves a number of other functions. For example, the song can be used to establish territory or to ward off predators. Cicadas also use their song to communicate with each other, sending messages about food sources or danger.
