Recently the significant decreases of species richness and abundance amongterrestrial animals including butterflies are reported due to habitat change,overexploitation, and global warming. We compared the butterfly speciescomposition and abundance from 1999 and 2014-2015 in a calcareous hill site ofthe middle part of Korea using a line transect method. There was a significantdecrease in the number of individuals (abundance) and the number of species(richness) from 1999 to 2014-2015. This decrease was more prevalent amongnorthern species than southern species, and the local extinct species were moreprevalent among northern species, showing the influence of global warming onbutterfly assemblages. However, no impact of habitat change was observed becauseof maintenance of the grasslands, which is caused by the dry soils of the calcareousregion.
