How do crickets produce their chirping sounds?

Crickets produce chirping sounds by rubbing their wings together in a process called stridulation. One wing has a serrated edge, similar to a file, while the other acts as a scraper. When the cricket moves its wings back and forth, the friction creates the chirping sound. The frequency and rhythm of the chirps vary by species and are often used to attract mates or establish territory. The sound is amplified by their body, making it audible over long distances.
