Description

The species composition of wild bees and their utilization pattern of flowers were surveyed from April to November in 2000 on the foot of Mt. Yamizo, Ibaraki Prefecture. A total of 1741 individuals belonging to 58 species in six families were collected. The most dominant family in both the numbers of species and individuals was Halictidae (18 spp. and 780 indivs.). Other major families were Andrenidae (17 spp., 135 indivs.) and Apidae (13 spp., 755 indivs.). Among the 58 species, 11 were regarded as dominant species, with the largest number of individuals (359) of Bombus diversus (Apidae). The 11 dominant species occupied 80.8% of all the individuals collected. The results were compared with those of a previous survey done in 1978 at the same location and those obtained from three other areas in Ibaraki Prefecture. The composition of the dominant species in the two surveys in Yamizo was nearly identical, and a very high similarity (Cλ=0.80) in community structure was observed between them. However, 34 (including nine unidentified species) out of 57 minor species, in which the number of individuals occupied less than 1% in the '78 survey, were not recorded in the present survey. A total of 138 flowering plant species were recorded during the survey, of which 57 species in 22 families were visited by bees. The largest number of bees (31.2%) was collected on asteraceous flowers. Among all the bee species, Lasioglossum apristum showed the highest value of resource state diversity (Bi=9.19).
