Stridulation

Stridulation is the act of producing sound by rubbing together certain body parts, often seen in various arthropods, such as crickets, grasshoppers, and some other insects. This process typically involves the scraping of a hardened part of the body (like wings or legs) against a rough surface. In crickets, for instance, the male rubs their wings together to produce a characteristic chirping sound, which is used primarily for attracting mates and establishing territory.
