Aquatic insects have been extensively studied to know their ecological relationship with other freshwater communities. One stable and one temporary pond- representing a wide hydroperiod gradient were selected from each district viz. Chennai (Chetpet and Koyambedu) and Kancheepuram (Chengalpet), India. Members of each genus of water bugs occupy a distinct habitat and exhibit diagnostic behaviour patterns. Micronecta s cutellaris prefers limnetic shallow water. Diplonychus rusticus inhabits water column as well as near the shores. Anisops bouvieri colonizes limnetic water column. Tenagogonus fluviorum occupies open water surface, preferentially under shade.
