Carpenter bees are species in the genus Xylocopa of the subfamily Xylocopinae. The genus includes some 500 bees in 31 subgenera. The common name "carpenter bee" derives from their nesting behavior; nearly all species burrow into hard plant material such as dead wood or bamboo. The main exceptions are species in the subgenus Proxylocopa; they dig nesting tunnels in suitable soil.
The Eucerini 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. They are most diverse in the Western Hemisphere.
Plebeia is a genus of mostly small-bodied stingless bees, formerly included in the genus Trigona. Most of the ~45 species are placed in the subgenus (Plebeia) (s.s.), but there also are four species in the subgenus (Scaura). They differ in only minor structural details, primarily of the hind leg, from other genera that were formerly treated as constituents of Trigona. In some classifications, the genus Schwarziana is treated as a subgenus within Plebeia, but recent morphological analyses indicate that Schwarziana is a distinct lineage, while Plebeia is paraphyletic.
Schwarziana is a relatively small genus of South American stingless bees. Like other stingless bees, Schwarziana are eusocial, with large colonies primarily composed of workers and one queen. Unusually for stingless bees, colonies are formed in underground chambers rather than in tree cavities. Workers are approximately 6.5mm long
The cosmopolitan bee genus Ceratina, often referred to as small carpenter bees, is the sole lineage of the tribe Ceratinini, and is not closely related to the more familiar carpenter bees. The genus presently contains over 300 species in 23 subgenera. They make nests in dead wood, stems, or pith, and while many are solitary, a number are subsocial, with mothers caring for their larvae, and in a few cases where multiple females are found in a single nest, daughters or sisters may form very small, weakly eusocial colonies. One species is unique for having both social and asocial populations, Ceratina australensis, which exhibits all of the pre-adaptations for successful group living. This species is socially polymorphic with both solitary and social nests collected in sympatry. Social colonies in that species consist of two foundresses, one contributing both foraging and reproductive effort and the second which remains at the nest as a passive guard. Cooperative nesting provides no overt reproductive benefits over solitary nesting in this population, although brood survival tends to be greater in social colonies. Maternal longevity, subsociality and bivoltine nesting phenology in this species favour colony formation, while dispersal habits and offspring longevity may inhibit more frequent social nesting in this and other ceratinines.
Melipona is a genus of stingless bees, widespread in warm areas of the Neotropics, from Sinaloa and Tamaulipas (México) to Tucumán and Misiones (Argentina). About 70 species are known. The largest producer of honey from Melipona bees in Mexico is in the state of Yucatán where bees are studied at an interactive park called "Bee Planet" which is within the Cuxtal Ecological Reserve.
Eufriesea is a genus of euglossine bees. Like all orchid bees, they are restricted to the Neotropics.
Tetragonula carbonaria is a stingless bee, endemic to the north-east coast of Australia. Its common name is sugarbag bee. They are also occasionally referred to as bush bees. The bee is known to pollinate orchid species, such as Dendrobium lichenastrum, D. toressae, and D. speciosum. It has been identified as an insect that collects pollen from the cycad Cycas media. They are also known for their small body size, reduced wing venation, and highly developed social structure comparable to honey bees.
The Indian stingless bee or dammar bee, Tetragonula iridipennis, is a species of bee belonging to the family Apidae, subfamily Apinae. It was first described by Frederick Smith in 1854 who found the species in what is now the island of Sri Lanka. Many older references erroneously placed this species in Melipona, an unrelated genus from the New World, and until recently it was placed in Trigona, therefore still often mistakenly referred to as Trigona iridipennis. For centuries, colonies of T. iridipennis have been kept in objects such as clay pots so that their highly prized medicinal honey can be utilized.
Tetragonula hockingsi is a small stingless bee native to Australia. It is found primarily in Queensland. The colonies can get quite large, with up to 10,000 workers and a single queen. Workers of Tetragonula hockingsi have been observed in fatal fights with other Tetragonula species, where the worker bees risk their lives for the potential benefit of scarce resources.
Caupolicana is a genus of bees in the family Colletidae, native to the Americas; most species are crepuscular in habit, visiting flowers only at dawn and/or dusk. There are over 50 known species, in 4 subgenera.
Epeolus is a genus of cuckoo bees of the tribe Epeolini, the subfamily Nomadinae part of the honey bee family Apidae. They are often known as variegated cuckoo-bees.
Sphecodes is a genus of bees from the family Halictidae, the majority of which are black and red in colour and are colloquially known as blood bees. Sphecodes bees are kleptoparasitic on other bees, especially bees in the genera Lasioglossum, Halictus and Andrena. The adults consume nectar, but because they use other bees' provisions to feed their offspring they do not collect pollen.
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.
Austroplebeia is a stingless bee (Meliponini) genus in the family Apidae. The genus was erected by Jesus Santiago Moure in 1961. The genus comprises five described species endemic to Australia and New Guinea.Austroplebeia are more closed related to the African stingless bees than rest of the species found in Asia and Australia.
Partamona is a genus of stingless bees in the family Apidae. Herbert Ferlando Schwarz in 1938 described the genus. The genus is found from Mexico to Brazil.
Tetragonula mellipes is a small eusocial stingless bee first described by Friese in 1898 and it is found in Northern Australia.
Paratrigona is a genus of bees belonging to the family Apidae.
Neocorynura is a genus of bees belonging to the family Halictidae.
Geotrigona is a genus of bees belonging to the family Apidae.
