Orthoptera Insect Ensifera courtship reproduction bioacoustics


The courtship, copulation and post-copulatory behavior, as well as acoustic communication of the Neotropical cricket Endecous (Notendecous) onthophagus is described under laboratory conditions and compared with other phalangopsids whose mating system was studied so far. We found that E. onthophagus present predictable mating sequences including seven events: (1) prolonged courtship; (2) male spermatophore extrusion during courtship; (3) female-above copulatory position; (4) prolonged copulation; (5) male forewings flipped over his head, exposing metanotal region along copulation; (6) copulation without spermatophore transfer; and (7) absence of guarding behavior. We suggest these events (1 to 7) as a behavioral line shared by phalangopsids, and we highlight variations that reflect the behavioral diversity of these crickets. The males of E. onthophagus produce the calling song (chirps) to attract females to mate, and also stridulates intermittently during the entire courtship period with distinct acoustic parameters during the stages of pre- and post-spermatophore extrusion.
