In order to find phenological change of butterflies due to global warming, we analyzed weekly monitoring data of butterfly at Gwangneung forest in 1958 and 2004. It was tested whether the timing of first flight and mean flight of butterflies in 2004 became earlier due to global warming compared with those in 1958 and whether the duration of flight period became longer. No significant difference was found in timing of first flight and in duration of flight period between 1958 and 2004. Furthermore, species showing delayed timing of mean flight was more abundant than species showing earlier timing of mean flight. Hence, the results do not confirm the predicted changes of phenology due to global warming. We discussed reasons on the non-apparent phenological changes despite the increase of temperature, and the problems and solutions in butterfly study on Korean butterfly fauna in utilization of butterflies as indicator for global warming.
