Flyways of the black swallowtail, Papilio maackii tutanus FENTON, are generally formed on the ridges or summits of hills. The spring flight activities of the black swallowtail were quantitatively observed at a flyway in Maruyama, Sapporo. The seasonal and diurnal trends of flight activities at the flyway coincided well with the phenological experience on this species. Among the main weather factors, insolation and wind velocity seem to be quite important. But it was suggested that the diurnal activities could not satisfactorily be explained by weather conditions alone. The directional nature of the flyway was quantitatively confirmed. The flyway under observation was a small one, with the highly concentrated portion of the traffic about 130m long. The behavior difference between P. maackii tutanus FENTON and P. bianor dehaanii C. and R. FELDER was briefly referred to. Finally, some comments on the butterfly flyway are given in the concluding remarks.
