Species and cladystic of butterflies is closely related to the preservation and utilization of biological resources in Indonesia. This study aims to determine species and cladystic of butterflies (Lepidoptera) in Grand Forest Park Central Sulawesi. Sampling of butterflies using a sweeping net with a purposive sampling method at three different watershed (DAS) locations, namely Vatutela, Kawatuna, and Poboya. Butterfly samples obtained at the research location were then identified at the Biology Laboratory, Faculty of Teacher Training and Education, Tadulako University. The results showed that there were 97 species from 5 butterfly families, namely Papilionidae (14 species), Pieridae (16 species), Nymphalidae (46 species), Lycanidae (15 species), and Hesperiidae (6 species). The research sample used for the analysis of kinship is 23 species from five butterfly families that dominate the research location. The observed characters included 32 characters. Analysis of kinship was calculated using the Sorensen similarity index, then processed using the Multivariate Statistical Package (MVSP) software. The closest kinship relationship is between the species Appias ithome and A. zarinda which is supported by a similarity index above 0.90 and the farthest relationship occurs between the species Bibasis sp. with other species from the Hesperiidae family which were supported by a similarity index below 0.7.
