The anatomical parts used to produce sound are quite varied : the most common system is that seen in grasshoppers and many other insects, where a hind leg scraper is rubbed against the adjacent forewing ( in beetles and true bugs the forewings are hardened ); in crickets and katydids a file on one wing is rubbed by a scraper on the other wing; in longhorned beetles, the back edge of the pronotum scrapes against a file on the mesonotum; in various other beetles, the sound is produced by moving the head up / down or side-to-side while in others the abdominal tergites are rubbed against the elytra; in assassin bugs, the tip of the mouthparts scrapes along a ridged groove in the prosternum; in velvet ants the back edge of one abdominal tergite scrapes a file on the dorsal surface of the following tergite.
