Abstract: Collections were made in 2014-2015 in Sălaj County, Romania resulting 168 Apidae specimens, belonging to 55 species. While the majority of them are common species, Andrena congruens Schmiedeknecht, 1883, Lasioglossum quadrisignatum (Schenk, 1853), and Chelostoma grandis (Nylander, 1852) are very rare species in the Carpathian Basin. Another rare species in Sălaj County were Lasioglossum pallens (Brullé, 1832), Chelostoma campanularum (Kirby, 1802), Chelostoma foveolatum (Morawitz, 1868), Osmia leucomelaena (Kirby, 1802), Melecta albifrons (Förster, 1771), Nomada platythorax Schwarz, 1981, and Bombus argillaceus (Scopoli, 1763). As for zoogeographical evaluation, the main species forming the Apidae assemblages were the widely spread Palaearctic species, as well as Mediterranean elements (Holo-Mediterranean, North Mediterranean, Ponto-Mediterranean). When evaluating the swarming dynamics of bees bivoltine species with long flying period seemed to be the most significant community components. Regarding the ecological or climate endurance characteristics euryoecious eremophilous species appeared to be the most significant.
