Aquatic insects exhibit high diversity and are abundant in freshwater habitats. Different varieties of aquatic organisms colonize freshwater ecosystems, which often contribute to most regional freshwater biodiversity. The literature was reviewed from 2011 to 2021, to provide the database of the distribution and diversity of aquatic insect in different area of India. According to published literature, the majority of aquatic insects belong to 10 taxonomic orders. These orders are Order Ephemeroptera, Order Hemiptera, Order Odonata, Order Coleoptera, Order Diptera, Order Tricoptera, Order Plecoptera, Order Lepidoptera, Order Collembola, Order Megaloptera. Overall species richness revealed that insect order Coleoptera were the dominant order followed by Hemiptera, Odonata, and Ephemeroptera. The presence of pollution intolerant genera viz., Petersulla, Isonychia, Isca, Clypeocaenis, Helicopsyche indicates that river water is of high quality. Cleon bimaculatum and Procleon regularum are tolerant to organic pollution. Consequently, an ecological study of aquatic insects can provide information about the ecology of insects in a specific area, which can be used as baseline data for future research and conservation planning. Therefore, the present study was attempted to compile all available information on the status and diversity of aquatic entomofauna in India.
