This study was carried out to clarify the change of butterfly community after clear cutting. Butterfly survey was conducted in clear cutting area, forest road, and forest using line transect method from May to November in 2011. A total of 32 species and 398 individuals of butterflies were observed. Abundance of food niche breadth and habitat type was significantly higher in clear cutting area than in forest. Estimated species richness and species diversity were significantly higher in clear cutting area than in forest. In clear cutting area, Leptidea amurensis and Argynnis niobe, vulnerable species, were abundant. This result suggests that grasslands formed by clear cutting play an important role to increase butterfly diversity in forest ecosystem.

Fragmented urban forests, as green islands within urban area, are the primary habitats for a vast number of different organisms inhabiting large cities. The areas of the urban forests are usually small, and hence, the proportion of the forest edge is relatively high. It is therefore expected that overall butterfly diversity may be lower than that of suburban or rural forests, and that those of grassland species, forest edge species, and generalist species with a wider niche breadth may be richer. Butterflies were surveyed weekly by the line transact method in order to characterize the butterfly community of the Hongneung Forest, a fragmented urban forest in Seoul. Butterfly richness of the study forest is much lower than those of main forests around or in Seoul. Grassland species, forest edge species, and generalist species were found to be richer, which was in agreement with the expected patterns of urban butterfly communities. Also, an endangered species, Spindasis takanonis, was observed in the Hongneung Forest, showing that urban forests play important roles for conservation of rare species.

The effects of number of host plants and nectar plants on the number and diversity of butterflies were monitored and analyzed by simple and multiple regression from May 2008 to Sep 2009 in the Bubjusa region (Mt. Sokri, Boeun-gun, Chungcheongbuk-do), which was divided into four regions. The results demonstrate that the number of butterflies has a positive correlation with the number of host plant species, the number of nectar plant species, and the number of host plants multiple regression analysis. The number of butterflies also increased habitat area. However, the butterfly species number and diversity index showed lower correlation with the number of host plants and the area size of the divided region, respectively, when analyzed by simple regression. In addition, increased species diversity in a region with more diverse plant flora. These results suggest that the composite distribution of host and nectar plants with diverse plant flora is required for butterfly diversity and population preservation. Additionally, it also suggest that vegetation types complementarity all factors.

The Baekdudaegan Mountain Range is home to a wide range of organisms inhabiting the Korean Peninsula. This study monitored butterfly communities of Guryongryeong (Myeonggye-ri) and Gojingkyeong (Seobyeok-ri) from April to September in 2013 to 2014, and the results were compared with previous data to determine changes in their distribution. We found 1,098 butterflies of 65 different species in Myeonggye-ri, and 1,161 butterflies of 63 different species in Seobyeok-ri. Comparing the two regions, 13 species appeared only in Seobyeok-ri and 15 species appeared only in Myeonggae-ri. When species were ranked according to number of individuals, the top species three species were as follows: Artogeia melete (127, 11.6%), A. napi (100, 9.1%), and Papilio maackii (90, 8.2%) in Myeonggye-ri; and Libythea celtis (146, 12.6%), A. napi (134, 11.5%), and Polygonia c-aureum (69, 5.9%) in Seobyeok-ri. The number of species with fewer than three individuals each was 24 in Myeonggye-ri and 23 in Seobyeok-ri, accounting for a high percentage among the total number of species. The similarities between the two regions were relatively high, and many of the butterflies are on the Red List of Korea. Compared with previous distribution data, there were no significant changes. This consistency indicates that the butterflies of the Baekdudaegan Mountain Range have been conserved well, and therefore the continuity in the Baekdudaegan Mountain Range is necessary to keep in the big picture.

Butterfly communities were monitored to investigate the emergence pattern with line transect method at Wolchulsan National Park through May to October in 2012. Totally 1,151 individuals belong to 49 species were monitored through the study period. Libythea celtis was a dominant species with showing 357 individuals(31%) followed by Pseudozizeeria maha 96 individuals(8.3%), Mycalesis gotama 75 individuals(6.5%) and Ninois dryas 72 individuals(6.2%) respectively. Among the monitoring periods, highest individuals and species(516 individuals belong to 30 species) were found at June and showed a high abundance near reservoir region. Highest diversity was shown at August with a Shannon index of 2.75 while lowest at October(Shanon index 1.78) and total diversity index was 1.71. Dominance values(Simpson index) showed highest at June with a value of 0.40 while lowest at September with a value of 0.07 and averaged 0.12. Kungol and Seongjeon compose a high similarity habitats with a similarity value of 0.52 and it was 0.17 at Kungol and Youngsan, lowest cases. Reservoir banks played a important role for habitats of specific species. It can be considered that they provide an open space of glass land for butterfly population, which was deficient at mountain area.

Mt. Hallasan in Jejudo has been well known as a habitat for both northern and southern limited butterflies and attracts the interests of many lepidopterists. In this study, the line transect method was used to monitor the community and similarity of butterflies monthly monitoring from May to September 2013, and the results were compared with the previous data. Through monitoring, 3,397 individuals in 26 species of 5 families were found in the present study. The monitored individuals belonging to 4 species (Aphantopus hyperantus, Eumenis autono, Lethe diana and Melanargia epimede) was 2,578 (75.9%), showing the prevalent species among the butterflies observed in the grassy area of the Mt. Hallasan. The butterflies inhabiting Mt. Hallasan showed higher similarity in the area where the open grassy space and the crowns of tree layer coexist than in landscape consisting of solely the tree layer or open grassy space. The habitation of butterflies by heights showed the altitudes between 1,665 to 1,700 m, located beneath the Baekrokdam (the crater) of Mt. Hallasan, possessed the most species and individuals. And it was also observed that the species that previously inhabited the subalpine zone moved to the area of higher altitudes together with the species that previously inhabited rather lower altitudes than the subalpine zone.
