Taxonomy
In addition to its historical classification (honey bees, bumble bees, stingless bees and orchid bees), the family Apidae presently includes all the genera formerly placed in the families Anthophoridae and Ctenoplectridae. Although the most visible members of Apidae are social, the vast majority of apid bees are solitary, including a number of kleptoparasitic species. The old family Apidae contained four tribes (Apinae: Apini, Euglossini and Bombinae: Bombini, Meliponini) which have been reclassified as tribes of the subfamily Apinae, along with all of the former tribes and subfamilies of Anthophoridae and the former family Ctenoplectridae, which was demoted to tribe status. The trend to move groups down in taxonomic rank has been taken further by a 2005 Brazilian classification that places all existing bee families together under the name “Apidae”, but it has not been widely accepted in the literature since that time.
