Andreninae
The bee subfamily Andreninae is a nearly cosmopolitan lineage, with most of its diversity in one genus, ''Andrena'', which contains over 1500 species. The remaining four genera in the subfamily only contain a total of 9 species. Females of three of the genera (''Ancylandrena'', ''Andrena'', and '' Megandrena'') have broad, velvety depressions called "facial foveae" on the face between the eyes and the antennae; in all other members of the family, the foveae are much smaller, typically reduced to grooves or pits at the upper margin of the eyes. ''Ancylandrena'' and ''Megandrena'' occur only in the desert regions of southwestern North America (Nevada, California, Arizona, Sonora, and Baja California), while ''Andrena'' is nearly worldwide. ''Euherbstia'' and '' Orphana'' are rare bees restricted to desert regions of Chile. Unlike the subfamily Panurginae, none of the species of Andreninae have yellow markings anywhere other than on the face; those markings, when present, are usually ...

Megandrena
''Megandrena'' is a genus of mining bees in the family Andrenidae The Andrenidae (commonly known as mining bees) are a large, nearly cosmopolitan family of solitary, ground-nesting bees. Most of the family's diversity is located in temperate or arid areas (warm temperate xeric). It includes some enormous gene .... There are at least two described species in ''Megandrena''.

Andrena
''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. Morphology ''Andrena'' are generally medium-sized bees; body length ranges between 8 and 17 mm with males being smaller and more slender than females. Most are black with white to tan hair, and their wings have either two or three submarginal cells. They carry pollen mainly on femoral scopal hairs, but many ''Andrena'' have an additional propodeal corbicula for carrying some pollen on their thorax. C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, Johns Hopkins University Press. They can be distin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euherbstia
''Euherbstia'' is a genus of mining bees in the family Andrenidae. The only species in this genus is ''Euherbstia excellens'', which is endemic to Chile. These bees have been observed to make nests in hard, compact soil, using cracks to enter the ground below. Females will make solitary nests. The female seeks out cracks in the ground, in which she digs a tunnel down to make her nest. She will repeatedly thump the walls of the tunnel with her abdomen, to make them more compact. Like all mining bees, they will create cells which they fill with pollen and eggs, closing them off until the larvae pupate and emerge the next year. Some larvae hibernate in a pupated state up to 2 years. This is probably because these bees live in an arid climate, where it is uncertain whether it will rain enough in a year to sustain the plants they need for food. As one generation of emerging adults might die because of drought, the next generation might survive, giving the species more chance of s ...

Panurginae
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 "facial foveae" of Panurgines are not broad, velvety depressions as in Andreninae, but reduced to grooves or pits at the upper margin of the eyes. The apex of the marginal cell of the wing is truncate, and the trochanteral scopa is reduced. Panurgines also frequently have yellow markings in locations other than on the face, a feature not seen in any other subfamilies of Andrenidae. Most members of this subfamily are oligolectic, with highly specialized floral associations, especially in desert species.
