On June 15, 2007 in the valley of the Ri- ver Raba near the village Marszowice (sou- thern Poland) Platycnemis pennipes (2 ) and Ischnura elegans (1 ) were caught to a light trap. Both species occurred nume- rously on the river or in an adjacent gravel- pit and they were probably activated by the strong light.
During the initial studies of a sand excavation in Borowa near Dęblin (51°31’N, 21°51’E, UTM EC50) 25 dragonfly species were recorded of which 23 were autochthonic or probably autochthonic. The most interesting were: Coenagrion lunulatum, Gomphus vulgatissimus, Crocothemis erythraea, Leucorrhinia albifrons and L. caudalis. The studied object seems to be a quite stable secondary habitat of the dragonfly assemblage rich in species with the species associated with lake littoral among others. The crucial factor inhibiting the succession of this assemblage is the use of the part of the water bodies as bathing waters.
