Abstract:

In the Łysogóry Mts and adjacent area 126 species of Apiformes were found. Mid-forest meadows in the Łysogóry Mts are populated mostly by Bombini (20 species). Apart from widely distributed species, the representatives of the following zoogeographical elements were collected in this area: one xerothermic montane species (Bambus mesomelas), several boreo-montane species (Andrena lapponica, Andrena tarsata, Osmia parietina, Bombus jonellus) and subpontic, submediterranean and subpontomediterranean species (Colletes succinctus, Andrena decipiens, Lasioglossum subfasciatum, Chalicodoma ericetorum, Osmia aurulenta, Ceratina cyanea, Anthophora pubescens). In the years 50-ies and 60-ies the number of Apiformes in the Łysogóry Mts reached 150 individuals per 100 m²; in the 80-ies the number of individuals was significantly lower. This condition was confirmed by a relatively low number of parasitic species (9) and by at least decuple decrease in number of Bombini.
