To provide regional biota data and basic data that define the change in the ecosystem caused by urban development and human interference, the study was conducted on moths living in Ibamsan (Mount) which is a neighborhood park situated in Mokpo-si, Jeollanamdo. A total of 21 collections and confirmations were made from May, 2007 to October, 2007. As a result of this study, 98 species of 86 genuses belonging to 14 families were identified and confirmed. Noctuidae numbered 45 species, the largest group among them followed by 18 species of Geometridae and 5 species of Arctiidae. It is presumed that street lights and landscape lights cause the lack of attracting light and the forested area is small and the vegetation is little as Ibamsan (Mount), an urban neighborhood park, is located at the center of the cultural and tourist facility. This study can be used for exhibitions of regional biota and educational purposes in the museum of natural history and to understand new trends of research and studies on moths living in cities.
