Qualitative investigations revealed 60 species of aquatic insects in 18 central Missouri lagoons which were sampled. Midges (Chironomidae) occurred in all lagoons, but three species predominated. The association of species was divisible into three distinct types based on one or more of the three dominant primary species of midges. Lagoons also could be categorized into three types using age, wastewater load, and relative abundance of midge larvae. Aquatic insects other than midges made up only a small percentage of the total number collected. Species of Diptera usually associated with water of high organic content increased in density from the more lightly loaded, newer lagoons to the more heavily loaded, older lagoons. Some beetles were found in all lagoons and one benthic dragonfly naiad was common in all lagoons. Some mosquito species bred in lagoons, particularly in their outlets.
