THE COURTSHIP AND MATING OF THE SCORPION, OPISTHOPHTHALMUS LATIMANUS

Authors


Summary.

  • 1The courtship and mating of the scorpion, Opisthophthalmus latimanus, are described.
  • 2In normal courtship the male initially grasps the female with his claws and then grips her chelicerae with his own, relinquishing his hold upon her pedipalps.
  • 3In this position the animals perform a “promenade à deux”. It is suggested that one function of the “promenade” is concerned with obtaining a clear area suitable for the deposition of a spermatophore.
  • 4The male deposits a spermatophore on the ground and pulls the female over it, so that part of the spermatophore enters her genital aperture. The pair then remain still for about five minutes; then they break apart.
  • 5The events accompanying unsuccessful courtship are described and suggestions are made as to the origin or significance of certain aspects of the behaviour pattern.
  • 6The similarity between the mechanism of insemination of this scorpion and the pseudoscorpions is considered.
