Male crickets chirp by rubbing their wings together rather than their legs.

The longer version

Sound production starts when a male lifts his forewings and draws a scraper on one wing across a ridged file on the other. Each ridge catches and releases, producing a rapid series of ticks that blend into the pulse of song rather than a single long tone.

Raising the wings also helps project the sound outward. Females listen with ears on their front legs and may move toward a preferred pattern, so the song works mainly as a calling signal. Different species keep to distinct rhythms, which helps females recognise their own kind and avoid wasted effort.
