This study was performed to examine the community structure of benthic macroinvertebrates at Water System of Mt. Juheul and its nearby area on August 21 and 21, 2011. Total taxa of benthic macroinvertebrates were 49 species, 26 families, 12 orders, 6 classes in 5 phyla. Aquatic insects were composed of 14 species in ephemeroptera, 12 species in trichoptera, 9 species in diptera, 3 species in plecoptera, 1 species in odonata, 1 species in hemiptera and 1 species in coleoptera. Other non-insects were composed of 3 species in annelida, 1 species in platyhelminthes, 1 species in nematomorpha and 1 species in mollusca. Indicator species in clean waters were Dugesia japonica in platyhelminthes, Drunella cryptomeri, Ephemerella denta in ephemeroptera, Nemoura KUa, Paragnetina flavotincta, Kamimuria KUa in plecoptera and Neonectes natrix in coleoptera. Occurrence species of benthic macroinvertebrates at each survey site at Mt. Juheul and its nearby area were 15~28 species and, individual numbers of those were 62~223 individuals/0.27m2. Species diversity indices and species richness indices of benthic macroinvertebrates were 2.59~4.07 and 3.18~4.99.
