Pseudoanthidium is a genus of bees belonging to the family Megachilidae. [1] The species of this genus are found in Eurasia, Africa and Australia.
Melitta is a genus of bees in the family Melittidae. It includes about 40 species restricted to Africa and the northern temperate zone. Most of the species are Palaearctic, though three rare species occur in North America.
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.
In biology, Lipotriches is a large genus of sweat bees in the family Halictidae, distributed widely throughout the Eastern Hemisphere though absent from Europe. There are nearly 200 species in 9 subgenera. They commonly have prominent bands of hair on the margins of the metasomal segments.
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.
Trachusa is a genus of leafcutter, mason, and resin bees in the family Megachilidae. There are at least 50 described species in Trachusa.
Anthidiellum is a genus of rotund resin bees in the family Megachilidae. There are more than 60 described species in Anthidiellum.
Pachyanthidium is a genus of bees belonging to the family Megachilidae. The species of this genus are found in Africa and Southern Asia.
Afranthidium is a genus of bees belonging to the family Megachilidae. The species of this genus are found in Southern Asia, Africa and Australia.
