The workers of B.diversus visited flowers of 76 species belonging to 31 families. Particularly, the flowers of Leguminosae, Labiatae and Liliaceae were visited predominantly by this workers. Moreover, they preferred mostly the flowers of Cirsium japonicum, Rosa multiflora, Vicia unijuga, Prunella vulgaris, Trifolium repens, Salvia chinensis, Impatiens textori, Pertya ovata, Astragalus sinicus and Styrax japonica. The workers of B.ignitus visited flowers of 24 species belonging to 14 families. The flowers of Leguminosae were visited predominantly by them.
