Total individual found was 200 butterflies. The value of Dominance Index was 0.10; Diversity Index was 1.09; Abundance Index was 180.55; Species Richness Index was 6.52 and Similarity Index was 0.42. Meanwhile in Pari River was found 14 species of butterflies consist of Jamides pura, Chersonesia rahria, Cupha erymanthis, Moduza procris, Polyura athatmas, Graphium sarpedon, Graphium antiphates, Papilio memnon, Appias lycinida, Eurema hecabe, Eurema sari, Hebomia glaucipe, Ixias undatus, and Pareronta valeria. The value of Dominance Index was 0.09; Diversity Index was 1.09; Abundance Index was 93.21; Species Richness Index was 6.53 and Similarity Index was 0.42 and the total individual found was 98 butterflies. The environment in Betung Kerihun-Danau Sentarum National Park was convenient to butterfly.
