Rophitinae is a subfamily of sweat bees in the family Halictidae. There are about 13 genera and more than 260 described species in Rophitinae. [1] [2]
These 13 genera belong to the subfamily Rophitinae:
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.
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.
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.
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.
Diadasia is a genus of bees in the family Apidae. Its species are oligolectic, specialized on a relatively small number of plant species.
Macrotera is a genus of bees native to North America, particularly diverse in the desert regions of the United States and Mexico. According to Wilson and Carril, there are "around 30" species of Macrotera. Macrotera are small to medium sized and often black or reddish in coloration. The genus was treated by P.H. Timberlake who, in addition to T.D.A. Cockerell, described most of the known species. Macrotera used to be considered part of the genus Perdita but was split apart by C.D. Michener in 2000. 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, particularly the plant genus Sphaeralcea and various Cactaceae.
Calliopsis is a genus of panurgine bees in the family Andrenidae. There are over 80 described species distributed throughout the western hemisphere.
Conanthalictus is a genus of sweat bees in the family Halictidae. There are about 13 described species in Conanthalictus.
Habropoda is a genus of anthophorine bees in the family Apidae. There are at least 50 described species in Habropoda.
Toxophorinae is a subfamily of bee flies in the family Bombyliidae. There are about 7 genera and more than 400 described species in Toxophorinae.
Phthiriinae is a subfamily of bee flies in the family Bombyliidae. There are about 11 genera and more than 120 described species in Phthiriinae.
Perdita coreopsidis is a species of bee in the family Andrenidae. It is found in Central America and North America.
Nomiinae is a subfamily of sweat bees in the family Halictidae. There are about 11 genera and at least 550 described species in Nomiinae.
Xenoglossa is a genus of large squash bees in the family Apidae. There are about 11 described species in Xenoglossa.
Anthophorula is a genus of bees in the family Apidae. There are more than 60 described species in Anthophorula.
Ammobatini is a tribe of cuckoo bees in the family Apidae. There are about 8 genera and more than 130 described species in Ammobatini.
Colletes hyalinus is a species of hymenopteran in the family Colletidae. It is found in North America.
Ancylandrena is a genus of mining bees in the family Andrenidae. There are about five described species in Ancylandrena.
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.
Perdita sexmaculata is a species of bee in the family Andrenidae. It is found in Central America and North America.
