The structure of Heteroptera communities was studied in two association-types of pine forests: the subcontinental (Peucedano-Pinetum) pine forest in Puszcza Białowieska and Puszcza Biata and the suboccanic (Leucobryo-Pinetum) pine forest in Bory Tucholskie and Roztocze. In the herb layer of these forests, 119 heteropteran species were registered, eurytopic species being the most abundant. In the canopies of pines. 101 species were found, with forest Heteroptera, especially stenotopes, being the most abundant. Euro-Siberian and Palearctic species were dominant in the herb layer, European and Euro-Siberian species - in the tree canopy layer. The greatest numbers of Imagines were registered in the early summer (June) - for the heteropterans of tree canopies, and at the turn of summer and autumn - for the heteropterans of the herb layer.
