How do crickets make that chirping sound?

A male cricket’s musical instrument is his wings rather than his legs. It is a common misconception that crickets use their legs to create chirping sounds. Actually they use their wings to do so. The sides of their wings are grooved in texture. They also have a jagged edge above the grooves. When these grooved sides of the wings are rubbed against each other, chirping sounds are produced. This action is called stridulation. This music can be produced with either wing, but research shows that most males prefer to use their right wings over the left. Female crickets do not chirp, as they do not have the same anatomy. Let us now look at the purpose of such behavior.
