The Cricket's Wing Song

Written by Studio AM.

On a warm evening, a field cricket's chirp may seem to rise from the grass. The sound does not come from its throat. A male cricket lifts his front wings and rubs a scraper on one wing across a row of tiny ridges on the other.

Each closing stroke makes the wing membranes vibrate. Those vibrations push the air, creating one pulse of sound. The opening stroke is usually quiet, so the rhythm follows the closing movements. Repeated strokes form a chirp or a longer trill. The pattern helps female crickets recognize a caller of their species, and males may use other songs during close encounters. Different cricket species produce different patterns. What sounds like one simple nighttime voice is careful motion made by two small wings.
