Bumblebees are also bees. Bumblebees belong to the large family Apidae. In Sweden we have about 300 species of bees. The honey bee (Apis mellifera) is one of these species while there are several hundreds of solitary bee species. The bumblebees consist of about 40 species. The SLU Swedish Species Information Centre lists 1/3 of all Swedish wild bee species as threatened and 1/5 of the butterflies as vulnerable or near threatened.
