stridulation

Stridulation is a method some animals use to produce sound by rubbing parts of their bodies together. For example, crickets have their wings made with tiny ridges; when they rub these ridges together, it creates a chirping sound. This behavior is often used to attract mates, establish territory, or communicate. The process involves the precise movement of body parts to generate vibrations that produce noise. Stridulation is common in insects like crickets and grasshoppers, but similar sound-producing behaviors are seen in other animals as well.
