Bees are winged insects closely related to wasps and ants, known for their roles in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey. Bees are a monophyletic lineage within the superfamily Apoidea. They are currently considered a clade, called Anthophila. There are over 20,000 known species of bees in seven recognized biological families. Some species – including honey bees, bumblebees, and stingless bees – live socially in colonies while most species (>90%) – including mason bees, carpenter bees, leafcutter bees, and sweat bees – are solitary.
Megachilidae is a cosmopolitan family of mostly solitary bees. Characteristic traits of this family are the restriction of their pollen-carrying structure to the ventral surface of the abdomen, and their typically elongated labrum. Megachilid genera are most commonly known as mason bees and leafcutter bees, reflecting the materials from which they build their nest cells ; a few collect plant or animal hairs and fibers, and are called carder bees, while others use plant resins in nest construction and are correspondingly called resin bees. All species feed on nectar and pollen, but a few are kleptoparasites, feeding on pollen collected by other megachilid bees. Parasitic species do not possess scopae. The motion of Megachilidae in the reproductive structures of flowers is energetic and swimming-like; this agitation releases large amounts of pollen.
The term cuckoo bee is used for a variety of different bee lineages which have evolved the kleptoparasitic behaviour of laying their eggs in the nests of other bees, reminiscent of the behavior of cuckoo birds. The name is perhaps best applied to the apid subfamily Nomadinae, but is commonly used in Europe to mean bumblebees Bombus subgenus Psithyrus. Females of cuckoo bees are easy to recognize in almost all cases, as they lack pollen-collecting structures and do not construct their own nests. They often have reduced body hair, abnormally thick and/or heavily sculptured exoskeleton, and saber-like mandibles, although this is not universally true; other less visible changes are also common.
Hylaeus is a large and diverse cosmopolitan genus within the bee family Colletidae. This genus is also known as the yellow-faced bees or masked bees. This genus is the only truly globally distributed colletid, occurring on all continents except Antarctica.
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.
Nomadinae is a subfamily of bees in the family Apidae. They are known commonly as cuckoo bees.
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 Stenotritidae is the smallest of all formally recognised bee families, with only 21 species in two genera, all of them restricted to Australia. Historically, they were generally considered to belong in the family Colletidae, but the stenotritids are presently considered their sister taxon, and deserving of family status. Of prime importance is that the stenotritids have unmodified mouthparts, whereas colletids are separated from all other bees by having bilobed glossae.
The Andrenidae are a large, nearly cosmopolitan family of solitary, ground-nesting bees. Most of the family's diversity is located in temperate or arid areas. It includes some enormous genera. One of the subfamilies, Oxaeinae, is so different in appearance that they were typically accorded family status, but careful phylogenetic analysis reveals them to be an offshoot within the Andrenidae, very close to the Andreninae.
Hesperocolletes douglasi, the Rottnest bee or Douglas's broad-headed bee, is a rediscovered species of plasterer bee that is endemic to Australia, and the sole known member of the genus Hesperocolletes.
Hylaeus alcyoneus, commonly known as the banksia bee, is a bee species endemic to Australia where it is commonly found in the coastal heaths of eastern and southern Western Australia. This bee is an important pollinator of Banksia species.
Verticordia aurea, commonly known as buttercups is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a slender, sometimes bushy shrub with a single stem at the base, cylindrical leaves and heads of scented, golden-yellow flowers in spring.
Colletes hederae, the ivy bee, is a species of plasterer bee belonging to the family Colletidae subfamily Colletinae.
Sphecodopsis is a genus of cleptoparasitic cuckoo bees in the family Apidae. Endemic to southern Africa, the wasp-like bees of this genus are generally small, varying from 3.9 to 9 mm in length, and mostly black, with orange-ish or reddish colouring of the metasoma in some of the species. The bee genus Scrapter is recognised as a host for the cleptoparasitic life cycle of some Sphecodopsis, but further data regarding preferred hosts is not available for most of the species.
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.
Colletes succinctus, the common colletes or heather colletes, is a species of Palearctic mining bee from the family Colletidae. It is part of the succinctus species group within the genus Colletes and is especially closely related to the ivy bee and the sea aster mining bee which are partially sympatric with C. succinctus but ecologically separate.
Diphaglossinae is a subfamily of bees in the family Colletidae. There are 9 genera and more than 130 described species in Diphaglossinae.
Colletes validus, colloquially known as the blueberry cellophane bee, is a solitary, specialist bee in the family Colletidae. It is found primarily in eastern North America where it nests in sandy soils near ericaceous plants.
Colletes similis is a species of plasterer bee belonging to the family Colletidae, subfamily Colletinae.
Colletinae is a subfamily of bees belonging to the family Colletidae.
