 note = {P(論文), Butterfly census was made in successive days at the campus of Hokkaido University, 1974, to know changes of flight activities in some different weather conditions (air temperature, insolation and wind force). Totally, 38 species and 17, 382 individuals were observed in this census. Butterfly flight activities increased sigmoidly with air temperature. Optimum temperature differed among species and generations. Insolation was not neccessary for their flight activities. The activities was depressed not only in an intense windy condition but also windless one.},
