The Bosscha Observatory is the only observatory that functions as an Astronomy research and education institution in Indonesia. The area around the Bosscha Observatory was formerly an agricultural area, but in line with current developments it is mostly a residential area. This research was conducted to study and monitor butterfly diversity at the Bosscha Observatory which was carried out previously in 2008. Butterfly observations were carried out using the standard walk method, namely by walking observing the presence of butterflies around the observation area. The observation radius is 5 m from the right, left, top and front of the researcher. Butterflies that were found and were already recognized were recorded, while those that were not yet recognized and were doubtful were caught using a sweep net. All butterflies found were recorded for their type and number of presences. The collected butterflies were brought to the laboratory for identification. Observations were made at 3 locations, the front yard, middle yard and back yard of the Observatory. Observation of butterfly activity was carried out at 08.00-16.45 WIB for 8 times in February 2020. Environmental conditions during the observation (temperature, humidity, and light intensity) were recorded using a data logger. From the observations, 35 butterfly species were found with a total of 955 encounters consisting of 5 families, namely 19 Nymphalidae species, 7 Pieridae species, 5 Papilionidae species, 3 Lycaenidae species, and 1 Hesperiidae species. Eighteen butterfly species in this study were also found in the 2008 study. There were 17 butterfly species that were found in this study but were not found in 2008, and 8 butterfly species that were found in 2008 but were not found in this study.
