Aquatic insects play an important role in the life cycle of fish because they provide feed for young fish. The insect and fisheries have become linked together, and to develop the inland fisheries need some consideration given by insects. Research was conducted in Pampangan Swamp focused on determine the species composition and community structure of aquatic insects in Pampangan swamp, Ogan Komering Ilir Regency, South Sumatra Province. Aquatic insect samples were collected from waters which dominated by grasses and water lily vegetation, using submersible insecting net. Similarity and diversity indices, evenness, and species richness, and important value index were constructed based on field data. The results showed that grass vegetation in Jungkal waters has the highest species richness, 39 individuals/m2 under nine species. Biological indexes such as diversity indexes, evenness indexes and dominance indexes were ranging from 0.24-0.75, 0.35- 0.43, and 0.19- 0.67. Important value index was ranging from 2.44 – 25.46, where the highest value is Belostoma flumineum. The condition of Pampangan swamp is in stable condition with the diversity pattern of aquatic insects which providing the feed for fish.
