Sprinkled Grasshopper


The family Acrididae use chemical clues to find mates along with characteristic songs produced by males to attract females during mating season.

Grasshoppers commonly use stridulation. 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.
