Abstrak. Santosa Y, Purnamasari I, Wahyuni I. 2017. Comparison of butterfly diversity in forested area and oil palm plantation. Pros Sem Nas Masy Biodiv Indon 7: 104-109. Land use change from the forested area into oil palm monoculture plantations was suspected to have reduced the number of biodiversities, including butterfly. In addressing such issues, this research was conducted from March to April 2016 in PT. Mitra Unggul Pusaka oil palm plantation of Riau Province and the forest area around the plantation. Data were collected from secondary forest and High Conservation Value representing forest areas, and oil palm plantations representing non-forest areas (young-growth oil palm and old-growth oil palm) simultaneously using 3 repetitions with time search method for 3 hours (8-10 pm). The results showed that there were 30 species (117 individuals) found belonging to five families, i.e.: Papilionidae (3 species), Nymphalidae (17 species), Pieridae (5 species), Lycaenidae (4 species), and Hesperidae (1 species). Species richness was greater in a forested area (Dmg=7.35) than in non-forested areas (Dmg=3.16). Based on the Similarity Index, 50% of the species in forested area were also found in non-forested areas. Therefore, it could be concluded that butterfly diversity in forested areas was higher than non-forested areas (oil palms).
