The Apidae is the largest family within the Apoidea, with at least 5700 species of bees, comprising the common honey bees, stingless bees (also used for honey production), carpenter bees, orchid bees, cuckoo bees, bumblebees, and various other less well-known tribes and groups. Many are valuable pollinators in natural habitats and for agricultural crops.
The family Apidae presently includes all the genera previously classified in the families Anthophoridae and Ctenoplectridae. Most of these are solitary species, though a few are also cleptoparasites. 
The four groups that were subfamilies in the old family Apidae are presently ranked as tribes within the subfamily Apinae. This trend has been taken to its extreme in a few recent classifications that place all the existing bee families together under the name "Apidae" (or, alternatively, the non-Linnaean clade "Anthophila"), but this is not a widely accepted practice.
The subfamily Apinae contains a diversity of 15 tribe lineages, the majority of which are solitary and whose nests are simple burrows in the soil.
However, honey bees, stingless bees, and bumblebees are eusocial or colonial. They are sometimes believed to have each developed this independently, and show notable differences in such characteristics as communication between workers and methods of nest construction.
- Emphorini—(Subtribe Ancyloscelidina; Subtribe Emphorina)
- Epeolini—(Subtribe Epeolina; Subtribe Odyneropsina; Subtribe Thalestriina)
Most members of this subfamily make nests in plant stems or wood.
