The procedure of making sound and the sounds they generate differ among the grasshopper groups that are called locusts. For example, slant-faced grasshoppers produce sound by rubbing spikes located on the inner surface of their hind legs against the edges of their front wings. The noise produced by these grasshoppers is a soft, muffled buzzing sound.
Band-winged grasshoppers sing only in the daytime and make a loud, snapping, or cracking sound with their wings as they fly.
