  • A sampling survey was conducted at three reservoirs of Junam wetland ($6.02km^2$) in Korea to identify the wetland insect fauna along with their dominance, diversity, richness and evenness. Methods of monitoring were visual inspection and sweeping in 2010, Malaise trapping in 2011, light trapping and pitfall trapping in 2012. In total, 9,269 individuals (36.3% coleopterans, 21.3% lepidopterans and 13.9% odonates) were collected, belonging to 574 species, 141 families and 14 orders. For the number of species, lepidopterans shared the highest (31.2%), followed by coleopterans (28.0%) and hemipterans (12.9%). Dominant species were Enochrus simulans (Coleoptera) (7.9% of total individuals) followed by Hydaticus grammicus (Coleoptera) (4.3%), Galerucella nipponensis (Coleoptera) (4.1%), Elophila interruptalis (Lepidoptera) (3.1%) and Apis mellifera (Hymenoptera) (2.2%). Total counts of coleopterans, lepidopterans and odonates in the three reservoirs were quite high, but the counts were not significantly different among the reservoirs. Insect diversity index (H') and richness index (RI) of the Junam wetland were 5.04 and 59.10, respectively.
