"Male grasshoppers produce sounds to attract a female mate. Grasshoppers make sounds in one of two ways – stridulation or crepitation.

Stridulation involves rubbing one body part, which acts as a rasp, against another, which acts as a scraper. Most grasshoppers stridulate to make their characteristic sounds. In grasshoppers, a row of pegs along the inside of the hind leg acts as a file, or rasp. The grasshopper rubs this leg surface against the thickened forewing, causing a vibration and thus a sound."
