Abstract: | Copulation behavior inMacrohaltica jamaicensis involved a complex, relatively stereotyped series of events both inside and outside the female. Only incomplete sperm transfer
occurred in many copulations. Some aspects of male copulatory courtship behavior performed during and following copulation
were consistently coordinated with particular stages in sperm transfer. This coordination suggests that copulatory courtship
may function to induce critical internal female responses which sometimes do not occur, such as relaxing the bursal muscles
to permit deeper penetration, and allowing sperm transfer to occur before the spermatophore is discarded. |
