Genetics: Three larval instars were recorded, the duration of each stage was found to be approximately 2-3 days with that of the pupal stage being about 3-4 days. Differences can be found in the timing of gerrids life cycle, which apparently separated the peaks of abundance and microhabitat preference of several species (Cheng, 1966; Jamieson, 1973). Podlipaev SA 1990. Aquarius najas (DE GEER, 1773) has a univoltine life cycle above the latitude of 53º47’ N, (BRINKHURST 1966) but may be bivoltine in warmer climates. The larvae construct pupal chambers in soft, moist soils in or along a stream bank. Alternatively, Gl individuals may enter diapause themselves, deferring reproduction to the following spring (univoltine life cycle). Life cycle of heteropterans. Some species feed on only one type of plant, while others are generalists, colonising many plant groups. Sea skaters are wingless throughout their life cycle. There are around 500 different species of pond skater that are known by a variety of different names including water striders, water bugs, magic bugs, skaters, skimmers, water scooters, water skaters, water skeeters, water skimmers, water skippers and Jesus bugs.
