Manger, R., 2007. Both Sympecma paedisca and Sympecma fusca in the same breedinghabitat. Brachytron 11(1): 83-86. In 2007 for the first time reproduction of the Siberian winter damsel Sympecma paedisca was observed outside the well known reproduction sites in the Netherlands. The distance from this peat hole to the peat bogs in De Weerribben is about 17 kilometers. It was also the first time both Siberian winter damsel and Common Winter Damsel S.fusca were observed together within the reproduction period for at least five weeks. The observations include both reproduction activity of Siberian winter damsel and Common Winter Damsel. The reproduction site is located along a stream and includes several mesotrophic ponds.
