How does a cricket make such a sound by just rubbing its legs together
In: Biology
The bottom of a [cricket](https://www.wonderopolis.org/wonder/how-do-crickets-talk-2#) [wing](https://www.wonderopolis.org/wonder/how-do-crickets-talk-2#) is covered with teeth-like ridges that make it rough. The upper surface of the [wing](https://www.wonderopolis.org/wonder/how-do-crickets-talk-2#) is like a [scraper](https://www.wonderopolis.org/wonder/how-do-crickets-talk-2#). When crickets rub the upper and lower parts of their wings together, they create a chirping sound called “stridulating.”
