Abstract： Insects in the Shuidonggou wetlands were assigned to 11 orders, 84 families and 182 species. Individual and species of Hemiptera and Diptera were more numerous than those of other orders, accounting for more than 60% of the total number of individuals collected. Phytophagous insects were more abundant than predatory and neutral insects. Insect species richness was high, and the community structure complex and stable. The curve of species-abundance was consistent with the log-normal distribution. Dominance within the predatory community varied greatly with the seasons, and dominance in the phytophagous and neutral insect communities was basically consistent with the seasonal changes
