The study on community structure of benthic macroinvertebrates from wetland Woopo was conducted for the long-term ecological monitoring. The wetland Woopo is located in Changnyeong-Gun, Gyeongsangnam - Do of Korea. In 2006, we investigated the seasonal variation of benthic macroinvertebrates with quantitative and qualitative collecting methods. The collection was performed monthly at four surveying region, Woopo, Sajipo, Mokpo and Topyong stream. In this study, 6 classes, 16 orders, 48 families, 95 species were identified on group of benthic macroinvertebrates. The species diversity index and the species richness index were the highest in Topyung region and it was 3.222 and 10.216 respectively. The two species, Cercion calamorum and Cloeon dipterum were quantitatively collected for 9 months. The changes of body lengths of 50 individuals were recorded and the advanced growth on the two species was expected from present study.
