The aims of this research were to determine colony, distribution, the natural prey of Nycteris javanica. This research was an ecological study using the Natural Snapshot Experimental data collection method. Purposive sampling was applied based on the population of the species, habitat quality, and its conservation status. Data on natural bat prey was obtained by dissecting the abdomen and removing the ventriculus, then dissecting the ventriculus and collecting segments of insect body parts. To assure biomass of its natural prey was done into two steps. The first step was made when N. javanica left the cave at nightfall. The second step was made when bats returned to the cave. Prey biomass was obtained by combining body weight after hunting and before hunting. The data of this study were analyzed using quantitative descriptive statistics. In this study, we found N. javanica only in 2 caves in Jonggrangan karst area. The natural prey consisted of 7 orders from Arthropoda (Araneae, Hemiptera, Orthoptera, Coleoptera, Lepidoptera, Blattaria, and Homoptera). Lepidoptera is the dominant prey of N. javanica. Prey biomass from N. javanica reached 48% of its body weight. © 2024 Author(s).
