Bee tribes

The tribe Euglossini, in the subfamily Apinae, commonly known as orchid bees or euglossine bees, are the only group of corbiculate bees whose non-parasitic members do not all possess eusocial behavior.

The Anthophorini are a large tribe in the subfamily Apinae of the family Apidae. Species in this tribe are often referred to as digger bees, although this common name is sometimes also applied to members of the tribe Centridini. It contains over 750 species worldwide, all of which were previously classified in the obsolete family Anthophoridae along with members of several other tribes; the vast majority of species in the tribe Anthophorini are in the genera Amegilla and Anthophora.

The Bombini are a tribe of large bristly apid bees which feed on pollen or nectar. Many species are social, forming nests of up to a few hundred individuals; other species, formerly classified as Psithyrus cuckoo bees, are brood parasites of nest-making species. The tribe contains a single living genus, Bombus, the bumblebees, and some extinct genera such as Calyptapis and Oligobombus. The tribe was described by Pierre André Latreille in 1802.

The Eucerini (often called longhorn bees or long-horned bees) are the most diverse tribe in the family Apidae, with over 32 genera worldwide that were previously classified as members of the family Anthophoridae. All species are solitary, though many nest in large aggregations, and large "sleeping" aggregations of males are found occasionally. Most genera are distinctive in the unusually long male antennae from which the tribe derives its name (eucer- means true horned). They are most diverse in the Western Hemisphere.

The Centridini are a tribe of large apid bees, many of which possess adaptations for carrying floral oils rather than (or in addition to) pollen or nectar. The floral oils are often gathered from plants of the family Malpighiaceae, though other plants may be visited. The oil-collecting species typically have "combs" composed of closely spaced, flattened, blunt bristles on the margins of the first tarsal segments of the front and middle legs; others may have velvety "pads" to absorb the oils. They also commonly gather plant resins for use in nest cell construction. They have a tiny pterostigma

Anthidiini is a tribe of insects in the family Megachilidae. There are at least 40 genera and 840 described species in Anthidiini. There is strong evidence that the tribe is monophyletic. thumb|Stelis lateralis

Osmiini is a tribe of leafcutter, mason, and resin bees in the family Megachilidae. There are about 19 genera and at least 1,000 described species in Osmiini. thumb|Osmia taurus

Ammobatini is a tribe of cuckoo bees in the family Apidae. There are about 8 genera and more than 130 described species in Ammobatini.

The Melectini are a tribe of medium- to large-sized cuckoo bees in the family Apidae, found essentially worldwide. They are brood parasites of the related typical digger bees (Anthophorini) and occasionally visit flowers.

Megachilini is a tribe of leaf-cutter and resin bees.

Halictini is a tribe of sweat bees in the sub-family Halictinae.

The bee tribe Ctenoplectrini of the subfamily Apinae, with the two genera Ctenoplectra and Ctenoplectrina, comprises 9 species in tropical Africa, 10 in Asia, and 1 in Australia.

The Osirini are a tribe of cuckoo bees in the family Apidae, all but one genus exclusively from the Neotropics, and laying their eggs in the nests of bees in the apid tribe Tapinotaspidini; the one exceptional genus is Epeoloides, which has one North American species and one European species, both of which attack the melittid genus Macropis.

The Tetrapediini are a tribe of apid bees.

The Exomalopsini are a tribe of bees in the family Apidae. They are tiny to moderate in size and usually hairy. The abdomen often has pale banding. They can be distinguished from other tribes by a line of hairs along the inner edge of the eye.

Augochlorini is a tribe of sweat bees in the subfamily Halictinae. They are found in the Nearctic and Neotropic realms. They typically display metallic coloration, with many species that are red, gold, green, blue, or purple.

The Emphorini are a tribe of apid bees.

The Rhathymini are a tribe of kleptoparasitic apid bees ("cuckoo bees").

Neolarrini is a tribe of cuckoo bees in the family Apidae. There are 5 genera and about 40 described species in Neolarrini, which includes the genera and species formerly included in the deprecated tribes Biastini and Townsendiellini.

The 'Tapinotaspidini' are a tribe of apid bees. They belong to the order Hymenoptera and the family Apidae. The Tapinotaspidini tribe consists of 180 different species. Many species of Apidae are recognised as oil-collecting bees and Tapinotaspidini possess this oil-collecting behaviour. It is maintained that mutualism exists between oil secreting flowers and oil collecting Tapinotaspidini bees. Morphological and molecular phylogenies have found that the trait of oil-collecting is polyphyletic. Tapinotaspidini are solitary bees which collect oil sources from flowers belonging to the families o

Dioxyini is a tribe of cuckoo bees in the family Megachilidae. There are eight genera in Dioxyini, comprising 36 species.
