The 'Apidae' are a large family of
bees, comprising the common
honey bees,
stingless bees (which are also cultured for honey),
carpenter bees,
orchid bees,
cuckoo bees,
bumblebees, and various other less well-known groups. Honey bees, stingless bees, and bumblebees are colonial (
eusocial), though they are sometimes believed to have each developed this independently, and show notable differences in such things as communication between workers. Carpenter bees are solitary, though they tend to be gregarious. The
nomadines are all
cleptoparasites in the nests of other bees.
The family Apidae presently includes all the genera that were previously classified in the families Anthophoridae and
Ctenoplectridae, and 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.
