Macropis is a genus of bees in the family Melittidae. They are very rare and were likely more common in the past. [1] [ when? ] They are associated with yellow loosestrife plants in the genus Lysimachia. [2]
Macropis species are of moderate size, not exceeding 15 mm. They have a livery predominantly black; males are characterized by conspicuous yellow markings on the head, but the females show morphological adaptations related to their foraging habits of flower oils, posterior tibiae with very developed, covered with a dense velvety hairs. [3] Unlike most Melittidae, the wing has only two submarginal cells.
They are solitary bees that dig their nests in the ground. Most species are oligolectic and feed on pollen and floral oils of Lysimachia spp. They make a single generation per year. The males emerge from the ground in spring, just before the females, and await the females in the vicinity of the flowers of the host plant. After mating, the females dig a nest in the ground, ending with one or two rooms in which is collected the pollen, which is placed on the egg. The larvae, feeding on the pollen, develop rapidly, and within 10 days turn into pupae, spending the winter in this stage. Macropis nests are often parasitized by bee cleptoparasites such as Epeoloides . [4]
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.
The Apinae are the subfamily that includes the majority of bees in the family Apidae. It includes the familiar "corbiculate" bees—bumblebees, honey bees, orchid bees, stingless bees, Africanized bees, and the extinct genus Euglossopteryx. It also includes all but two of the groups that were previously classified in the family Anthophoridae.
Melittinae is a small melittid subfamily, with some 60 species in four genera, restricted to Africa and the northern temperate zone. They are typically small to moderate-sized bees, which often have shaggy scopae, and are commonly oligolectic; several species further specialize on floral oils as larval food rather than pollen, including Rediviva emdeorum, a highly unusual species in which the forelegs are longer than the entire body, and used to sponge up the floral oil at the end of elongated corolla spurs of the host plant, Diascia.
Andrena is a genus of bees in the family Andrenidae. With over 1,500 species, it is one of the largest genera of animals. It is a strongly monophyletic group that is difficult to split into more manageable divisions; currently, Andrena is organized into 104 subgenera. It is nearly worldwide in distribution, with the notable exceptions of Oceania and South America. Bees in this genus are commonly known as mining bees due to their ground-nesting lifestyle.
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.
Amegilla is a large genus of bees in the tribe Anthophorini. It has been split into many subgenera, including Asaropoda, Micramegilla,Notomegilla and Zonamegilla.
Mass provisioning is a form of parental investment in which an adult insect, most commonly a hymenopteran such as a bee or wasp, stocks all the food for each of her offspring in a small chamber before she lays the egg. This behavior is common in both solitary and eusocial bees, though essentially absent in eusocial wasps.
Dasypoda is a genus of bees in the family Melittidae.
Epeoloides pilosulus is one of only two species in the bee genus Epeoloides; it is kleptoparasitic in the nests of melittid bees of the genus Macropis. Known to exist in only a handful of localities in the northeastern United States and adjacent parts of Canada, this species is classified as Endangered by the State of Connecticut.
Hesperapis is a genus of bees in the family Melittidae. There are at least 30 described species in Hesperapis. The genus is very uncommon and is restricted only to coastal barrier islands in the Gulf of Mexico and dunes of the Great Lakes. Its abdomen is flattened and its integument or "skin" is soft compared to other groups of bees.
Macropis nuda is a ground nesting, univoltine bee native to northern parts of North America. Thus, this species cocoons as pupae and hibernates over the winter. The species is unusual as it is an oligolectic bee, foraging exclusively for floral oils and pollen from Primulaceae of the species Lysimachia ciliata.
Dasypoda hirtipes, the pantaloon bee or hairy-legged mining bee is a species of solitary mining bee from the family Melittidae. It is a widespread bee which is found from Great Britain to China.
Melittidae is a small bee family, with over 200 described species in three subfamilies. The family has a limited distribution, with all described species restricted to Africa and the northern temperate zone.
Epeolus is a genus of cuckoo bees in the family Apidae. They are often known as variegated cuckoo-bees. The species is uncommon to rare, and has strong patterns of black and white on the thorax and abdomen. These patterns are made of tiny fat hairs lying flush with the integument or "skin" of the bee. It is easily mistaken for Triepeolus, but is almost always smaller.
Dieunomia is a genus of sweat bees in the family Halictidae. There are about nine described species in Dieunomia. These bees are relatively uncommon, and are larger than almost every other genus in Halictidae other than Nomia. The wing has two submarginal cells, and the usual bent vein of the basal vein is only weakly present. The male has greatly dilated middle tarsi.
Florilegus condignus is a species of long-horned bee in the family Apidae. It is found in the Caribbean Sea, Central America, and North America. It is an uncommon species in general but may be locally common near wetlands containing pickerelweed. It is often mistaken for species of the genus Melissodes.
Hesperapis oraria, or Gulf Coast solitary bee is a rare species of bee in the family Melittidae. It was first described in 1997. The bee's current known range is on the barrier islands and coastal mainland secondary dunes on the Gulf Coast of the United States in Florida, Alabama, and Mississippi. The Gulf Coast solitary bee is the only known member of its subfamily in the eastern United States, and it is a monolege of the coastal plain honeycomb head.
Dasypoda delectabilis, the delightful pantaloon bee, is a species of solitary bee from the family Melittidae. It was described in 2023 based on a single male specimen caught in arid areas of south-eastern Iran.
Dasypoda radchenkoi, also known as Radchenko's pantaloon bee, is a species of solitary bee from the family Melittidae. It was described in 2023 in the scientific journal Osmia based on specimens caught in the limestone areas of southern Spain.
