Abstract

Information from multiple sensory systems is likely combined to provide guidance for male muscoid flies engaged in aerial pursuit of females. To specify the female's position to the thoracic flight motor, head-centered visual information should be integrated with propriosensory information about head position relative to the thorax because the flies' heads are flexible around the neck. Head position is encoded by a proprioceptive organ in the ventral neck membrane. We determined in the flesh fly Neobellieria bullata (Sarcophagidae) that accurate propriosensory information is necessary for aerial capture of females by shaving mechanosensory hairs from the organ in male flies and competing them against their sham operated brothers in pursuits of virgin females. We also determined that normal male flies are not successful at capturing females until the second day post-eclosion.
