Species composition, dominance structure, and phenology of bees (Apiformes) was studied in the Białowiea National Park, which is a part of the most extensive primeval forest on the European Plain, the Białowiea Forest (NE Poland). In total 146 species of Apiformes are reported from the park. Beside the more or less abundant honey bees, the major bee species is Bombus lucorum, accounting for about 30% of wild bees and as much as 71.5% of bumblebees recorded there. Among 3 other bee species dominating in a large part of Poland, Bombus pascuorum accounts for nearly 11% of bumblebees, while B. terrestris and B. lapidarius are accessory species in the park. This shows approximately how the bee fauna looked like in most parts of Poland and Central Europe before human activity started to change the landscape radically, starting from the Middle Ages.

Studies were carried out at 36 localities in Pogórze Przemyskie (the Przemyśl Foothills) and adjacent areas along the San River (SE Poland) in the years 2004-2007. 54 species of dragonflies (74% of the Polish dragonfly fauna) were recorded, among them: a) Nehalennia speciosa in a highly isolated population, currently situated at the southern border of the species distribution, b) Crocothemis erythraea at 5 localities, autochthonous at least at two of them, abundant at one site, and with a probable second generation, c) Cordulegaster bidentata, widespread at many localities, d) Leucorrhinia albifrons and L. caudalis at the southern border of their distribution, the latter species being extremely rare at these latitudes, e) L. pectoralis, rare in southern Poland, f) several thermophilous species as e.g. Aeshna affinis, Orthetrum brunneum, Orthetrum albistylum, Sympetrum meridionale. The species composition of the odonate fauna and the occurrence of some species are commented on and discussed with reference to the geographical position of the area and the habitat spectrum. Conservation aspects are presented and assessed and some conservation measures are proposed.
