Species diversity of ant fauna inhabiting the university campus in the Seoul Metropolitan city, Hanyang University is documented in this investigation. Totally, 14 species of 8 genera belong to 3 subfamilies discovered in study area. Our results are compared with the previous works on ant fauna in the forest and urban habitats based on species number difference. In study area, site 12 and 13 contain wide forest area and diverse environmental elements such as rotten wood, leaf mold and group of living tree. Site 7 has small forest area, but show wide variety of environments like site 12 and 13. Urbanized region like site 8, 10 or area in construction like site 1 show the most lowest diversity. Aside from diversity, Four ant species, Paratrechina flavipes, Lasius spp., Camponotus japonicas, Tetramorium caespitum, appear at almost all habitat, seems to have strong tolerance to environmental change.
