Abstract: To explore community structure and diversity of butterfly in the Shiwandashan National Forest Park district of Guangxi, five different habitat types were selected in this region, and a2 km transect was set for each habitat. We investigated butterfly species and abundance fromApril to September in 2016-2018, and analyzed the diversity and compositional similarity of different habitats. A total of 3734 individuals from 155 species belonging to 88 genera and 5 families were collected. Eurema blanda and Stichophthalma howgua were the most abundant species, which accounted for 16.60% and 25.98% of the total abundance, respectively. The number of rare butterfly species was 75. The numbers of genus and species of butterfly in the habitat of mixed farming and forestry area were significantly higher than those in the shrub, lakeside area, conifer and hardwood mixed forest, and rain forest. Butterfly richness in the habitat of mixed farming and forestry area and shrub was significantly higher than those in other habitat types. The highest similarity coefficient was found between the habitats of shrub and lakeside area (0.42), while the lowest was between the habitats of shrub and rain forest (0.29). There was no difference of number of genus, species and individual, and diversity index, evenness index, dominance index and richness index among different months. Therefore, environmental protection of butterflies is recommended in Shiwandashan National Forest Park district due to the high richness of rare butterfly species.
