抄録

Copulatory behavior of the crayfish Procambarus clarkii was observed in the laboratory. This behavior was asymmetrical, in that the male mounted the female and grasped her chelipeds with his chela. Crayfish in various combinations (1 female and 1 male, 1 female and 2 males, and 2 females and 1 male) were confined in an aquarium and observed. The number of copulations, the number of copulation attempts by males, total duration of copulations, and the average duration of a copulation were not different among the 3 combinations. Females initiated behavior similar to the copulatory behavior initiated by males only in experiments with 2 females and 1 male. The frequency of this reversed copulatory behavior was greater in the experiments with 2 females and 1 male than it was with the other 2 combinations.
