The diversity of butterflies (Insecta: Lepidoptera) in Purwodadi Botanical Garden, Pasuruan, East Java, Indonesia. Pros Sem Nas Masy Biodiv Indon 5: 172-178. Purwodadi Botanical Garden (PBG) is one of botanical and conservation center. The ecosystem in PBG provide the growth and development of butterflies. Butterflies is an insect that classified in order of Lepidoptera. The number of butterflies in Indonesia are 2000 species. The aim of this research are to identify the diversity and dominance of butterflies in PBG. The study were conducted on July, 28-30th, 2018 at 07.30-11.00 a.m. and 14.00-16.30 p.m. Active method by sweeping net and often called as “Butterfly walks”were used in this research. There are two study area that is main pathways that have long 1 kilometers and width 500 meters. The butterflies that were catched then identified by Miller and Miller (2004), Pegi and Amir (2006), Landman (2001), and Borror et al. (1992). The results of this research shows that the diversity in PBG is 2.02, it means that the level of diversity in PBG is moderate. The dominance index in PBG is 0.21, it means that this community in stable condition and there’s no species that were dominated. Research about butterflies are urgent regarding to the conservation program. The conservation of butterflies can do through many ways such as maintaining habitats, law enforcement, and cultivation.
