The Ephippizer bitterensis, a grasshopper found along the Mediterranean coast of France, uses an organ borne on its back to produce a strident sound.

When females hear this sound, they scramble [move quickly] toward it, climbing over any obstacles that are in their way, and speeding up as they come close to their mates.
