Indonesia is a country with a rich diversity of flora and fauna. UPI Botanical Garden is one area that is used as a natural laboratory for students majoring in Biology Education FPMIPA UPI. UPI Botanical Garden are also composed of many plants that can support the life of various of Lepidoptera. This study aims to determine the diurnal butterfly diversity and its relationship with the presence of the host plant. The data of this study are also expected to support and provide information necessary for the formulation of a management plan recommendations butterfly conservation not only in the Botanical Garden UPI but also in other places. Diversity adult butterfly larvae sampled using standard Cruising methods. The results showed that there were 40 species of butterflies and 13 species of adult butterfly larvae with Delias belisama with the greatest abundance value (0.158 ± 0.063). While the lowest butterfly species adult’s abundance were Melanitis leda (0.001 ± 0.003), Elymnias hypermnestra (0.003 ± 0.006), Euthalia Monina (0.003 ± 0.006), Athyma nefte (0.003 ± 0.006) and Amathusia phidippus (0.002 ± 0.003). In the research, also found endemic butterflies Cyrestis lutea which is only exist in Java and Bali Island, Indonesia. As for the number of host plant species of butterflies found in the Botanic Gardens UPI are 34 species. So the vegetation composition Botanical UPI supports the existence and diversity of butterflies.
