The present investigation will contribute towards the knowledge of the assessment of species diversity of aquatic insects of the Sai River at Raebareli district of U.P. Monthly sampling of aquatic insects was conducted at three sites of the river during July 2022 to December 2022. A total of 22 genera belonging to 6 orders and 18 families were identified. Among them, the order Hemiptera was the most dominant, followed by the order Odonta (5 genera), Diptera (3 genera), Coleoptera (2 genera), Trichoptera (2 genera) and Ephemeroptera (2 genera). The study shows many parts of the river started to deteriorate hence the complete absence or less abundance of sensitive/ pollution intolerant species are less in the study. Therefore, immediate attention and proper maintenance of the river is to be suggested.
