Reproduction
The Woodland Pondsnail is dioecious species. This means that they have separate sexes and they reproduce sexually. Although the two sexes do not look any different externally it is impossible for them to self-fertilize because of the physiological and behavior mechanisms they use for fertilization.
The adult females lay their eggs in the shallow shoreline from May-July. The eggs survive best when the water is around 15°C. (Pinel-Alloul, 1979)
