The sexual and physiological character of the adults of Fannia scalaris F., which swarmed and mated under the willow street tree, was studied from 1957 to 1960 in Sendai. Individuals alighted on the tree and being in each stage of the mating behavior were caught and examined as to sexual characters, physiological age and impregnation of the females. The results are as follows : Only physiologically old maies swarmed and carried out mating behavior. They pursued other individuals indiscriminately and tried to mate, but finally only the pairs of old male and physiologically middle aged unimpregnated femaie copulated. Females seemed to copulate only once in this species. From the studies mentioned above, it was concluded that the swarming of this species was the precopulation behavior and each stage of the mating behavior was the most effective serching process of males for unimpregnated females in trial and error.
