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, which dig nesting tunnels in suitable soil.
Ptiloglossa is a small genus of bees within the family Colletidae, endemic to the Americas. Ptiloglossa is one of the most common nocturnal groups of colletids.
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.
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.
Lestrimelitta is a genus of stingless bees found in the Neotropics, from Mexico to Brazil and Argentina, with about 20 known species. They are small, shining black species from 4 to 7 mm in length, with rounded heads and reduced pollen baskets. Unlike most eusocial bees, they do not gather their own pollen and nectar from flowers, thus are not pollinators, but instead they invade the colonies of other stingless bee species and rob their pollen and honey stores. They do not initiate their own nests, but they will "evict" another stingless bee colony from its nest, and convert the pre-existing nest to house their own colony.
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 in the family Apidae. They are often known as variegated cuckoo-bees.
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.
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.
Leurotrigona is a genus of bees belonging to the family Apidae.
Dolichotrigona is a genus of bees belonging to the family Apidae.
Scaptotrigona is a genus of bees belonging to the family Apidae.
Tetragona is a genus of bees belonging to the family Apidae.
Scaura is a genus of bees belonging to the family Apidae.
Paratrigona is a genus of bees belonging to the family Apidae.
Oxytrigona is a genus of bees belonging to the family Apidae.
Nogueirapis is a genus of bees belonging to the family Apidae.
Geotrigona is a genus of bees belonging to the family Apidae.
