Epeolus is a genus of cuckoo bees in the family Apidae. [1] They are often known as variegated cuckoo-bees.
The species within Epeolus are medium-sized bees with bright patterns. There are currently approximately 100 species described from throughout the world. All known species of Epeolus are cleptoparasites of mining bees of the genus Colletes . The female enters the nesting excavated by the female Colletes bee and lays an egg in an unsealed cell. The Epeolus larva then consumes the egg of the host bee and then feeds on the pollen the Colletes bee provisioned the cell with for her offspring. Epeolus bees may be rather obvious and easily observed in the vicinity of the nesting aggregations of their hosts and often use the same flowers to feed on. [2] Colletes bees line their nesting cells with a cellophane like covering which they exude from the Dufour's gland to protect the cell from moisture and fungal infection, [3] female Epeolus bees have spines on the end of their abdomens which they use to pierce u-shaped holes in this covering so that she can oviposit between its layers, she also secretes a small amount of glue so that the egg adheres to the cell. [4]
The following species are currently classified in the genus Epeolus: [5]
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.
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.
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.
Thyreus is an Old World genus of bees, one of many that are commonly known as cuckoo bees, or cloak-and-dagger bees, and are kleptoparasites of other species of bees, mostly in the genus Amegilla. They all have strongly contrasting patterns of coloration – three species from the Sydney region, Thyreus nitidulus, T. lugubris, and T. caeruleopunctatus are bright blue and black.
Sphecodes is a genus of cuckoo 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.
Melecta is a genus of cuckoo bees in the family Apidae. There are at least 50 described species in Melecta.
