Seasonal changes in adult age structure of three drosophilid species (Drosophila okadai, D. neokadai and D. qua.driseta.ta) that dwell near waterside at highlands in central Japan were surveyed in Shiga Heights, Nagano Prefecture in 1996. Judging from the increase of females having undeveloped ovaries, D. okadai seemed to pass three or two generations in a year in Shiga Heights. D. neokadai appeared later than D. okadai in spring, so that this species seemed to pass two or three generations in a year in this area. Since only a few specimens of D. quadrisetata were collected between mid-summer and autumn, precise voltinism of this species could not be inferred from this survey. However, this species also seemed to pass two or three generations in a year in this area.
