Protandrenini is a tribe of mining bees in the family Andrenidae. There are at least 12 genera and at least 380 described species in Protandrenini. [1]
These 12 genera belong to the tribe Protandrenini (some authors treat subgenera within this classification as genera):
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.
The Bombini are a tribe of large bristly apid bees which feed on pollen or nectar. Many species are social, forming nests of up to a few hundred individuals; other species, formerly classified as Psithyrus cuckoo bees, are brood parasites of nest-making species. The tribe contains a single living genus, Bombus, the bumblebees, and some extinct genera such as Calyptapis and Oligobombus. The tribe was described by Pierre André Latreille in 1802.
The bee subfamily Panurginae is a diverse lineage of 33 genera in 7 tribes. They are particularly diverse in the New World, though scarce in the tropics, and in the Old World they can be found primarily in the Palaearctic and Africa, but absent from Australia and tropical Asia. They tend to be associated with xeric or sandy habitats.
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.
Perdita is a large genus of small bees native to North America, particularly diverse in the desert regions of the United States and Mexico. There are over 600 currently recognized species of Perdita, plus more than 100 additional subspecies and many more species that remain undescribed. Perdita are usually quite small and often brightly colored with metallic reflections and/or yellow or white markings, and among the few lineages of bees incapable of stinging. The genus was extensively treated by P.H. Timberlake who, in addition to T.D.A. Cockerell, described most of the known species. Most species are extreme specialists (oligoleges) with respect to pollen and will only collect pollen from a few closely related species or genera of plants. Many species in this genus are called fairy bees.
Leioproctus, the hairy colletid bee, is a genus in the plaster bee family Colletidae. Its members are primarily found in Australasia and temperate South America, and include the most common native bees in New Zealand.
Calliopsis is a genus of panurgine bees in the family Andrenidae. There are over 80 described species distributed throughout the western hemisphere.
Calliopsini is a tribe of mining bees in the family Andrenidae. There are at least 120 described species in Calliopsini.
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.
Osmiini is a tribe of leafcutter, mason, and resin bees in the family Megachilidae. There are about 19 genera and at least 1,000 described species in Osmiini.
Megandrena is a genus of mining bees in the family Andrenidae. There are at least two described species in Megandrena.
Lithurgus is a genus of bees in the family Megachilidae.
Pseudopanurgus fraterculus is a species of bee in the family Andrenidae. It is found in Central America and North America.
Macrotera opuntiae, the sandstone mining bee, is a species of bee in the family Andrenidae. It is found in North America. As the specific name suggests, these bees are pollinators of Opuntia cacti.
Panurgini is a tribe of bees in the family Andrenidae. There are about 9 genera and more than 830 described species in Panurgini.
Brachynomada is a genus of cuckoo bees in the family Apidae. There are about 16 described species in Brachynomada.
Andrena astragali, the death camas miner bee or death camas bee, is a species of miner bee in the family Andrenidae. It is found in North America. It specializes in feeding on the highly poisonous Toxicoscordion venenosum, the meadow deathcamas, and close relatives. It is quite likely the only bee that can tolerate the deathcamas toxin, zygacine.
Ammobatini is a tribe of cuckoo bees in the family Apidae. There are about 8 genera and more than 130 described species in Ammobatini.
Protandrena is a genus of mining bees in the family Andrenidae. Depending upon whose definition of the genus one follows, there are anywhere from 50 to 180 described species in Protandrena; traditional classifications recognize 7 subgenera, some of which are sometimes elevated to genus rank, and other classifications place many of these species in the related genus Pseudopanurgus (e.g.), leaving Protandrena with a much smaller constituency. In the most inclusive definition, they are found from Canada through Argentina. However, there is current disagreement whether the Protandrena in South America belong to different genera, in which case the genus extends only as far south as Panama. They are solitary bees, but some species nest in aggregations. They prefer to nest in sunny areas with sparse vegetation. The underground nests have cells lined with a chemical substance. This "wallpaper" acts as a barrier between fungi and bacteria. The eggs hatch, the larvae develop, and then overwinter as mature larvae with hardened skin. They are primarily active from May to October, but have been noted to be active in April in the region six of the United States.
Protandrena cockerelli is a species of bee in the family Andrenidae. It is found in North America.
