Female bushcrickets locate their mates by sound. Auditory acuity is mediated by the complex anatomy of the tympanal slits, associated trachea, and spiracle. By manipulating the acoustic properties of this system and measuring the neural output, a bilobed, highly directional mechanism associated with the slits is observed, confirming Autrum's original hypothesis.
