Chittaura Jheel, located in the Bahraich district of Uttar Pradesh, is one of the largest natural wetlands in the region, spanning approximately 15 hectares. This ecologically significant wetland supports a rich diversity of flora and fauna. To evaluate the aquatic insect diversity of Chittaura Jheel, a survey was conducted in 2022. The findings revealed a high diversity of aquatic insects, with representatives from seven insect orders: Hemiptera, Coleoptera, Odonata, Diptera, Ephemeroptera, Lepidoptera, and Trichoptera. Hemiptera was the most dominant group, comprising 31.94% of the insect population, followed by Coleoptera (25.13%), Odonata (18.58%), Diptera (10.21%), Ephemeroptera (7.07%), Lepidoptera (4.71%), and Trichoptera (2.36%). Diversity indices were also calculated to better understand species distribution within the ecosystem. The dominance of Hemiptera, Coleoptera, and Odonata indicates that Chittaura Jheel is relatively less polluted and supports a healthy aquatic environment.
