Insects were collected from the edge as well as deep water of the ponds by nets and hand pickup. Collected specimens were preserved in 70% alcohol and Identification up to family level was carried out following different available keys and up to generic and species level by using the keys of Distant. A total of 17 species of Hemiptera were recorded which belongs to 12 genera and 9 families. Numbers of species identified in each family reached 3 in Corixidae, 2 in Pleidae, 2 in Notonectidae, 3 in Belostomatidae, 3 in Nepidae, and 1 species to each family of Gerridae, Hydrometridae, Veliidae and Mesoveliidae.
