Overwintering adults of a water strider, Aquarius paludum having the macropterous and brachypterous wing forms continued to lay eggs for about 35 days in spring. The oviposition occurred at a high and constant rate under quasi-natural conditions. There was no significant difference between the two wing forms with respect to the number of eggs throughout their most reproductive period. Some of the second generation adults which had overwintered after reproduction in the previous autumn also became reproductively active in the following spring together with the third and diapause generation adults. In early spring, macropterous adults appeared on the water surface later than brachypterous adults, demonstrating the longer distance between diapause sites on land and breeding sites on the water surface in macropterous adults than brachypterous adults.
