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.

Andrena Bicolor
''Andrena bicolor'', or Gwynne's mining bee, is a common and widespread Western Palearctic mining bee which is found over most of Europe as well as North Africa and the Middle East and which reaches eastwards into Siberia. Description ''Andrena bicolor'' is a small to medium-sized mining bee, with the males being slightly smaller than the females. The females have a coat of reddish-brown hairs on the dorsal surface of the thorax, a wholly black-haired face and indistinct bands of yellowish hairs on the margins of the first to third tergites. The spring brood can show an extensive black hair covering on the femur and the sides of the thorax, this is not as marked in the autumn brood. It has dark tibia on the hind legs but these have obvious orange hairs which have been said to resemble a pair of orange leg warmers. The spring brood males have black hairs on the head and side of the thorax and lack the bright colours of the females, while summer brood males often show brown hairs on ...

Andrena Agilissima
''Andrena agilissima'' is a species of mining bee. They are present in most of Europe, the Near East and North Africa and can be found from April through July. ''Andrena agilissima'' is an '' oligolectic'' species, feeding only on the pollen of a few genera of Cruciferous vegetables (Brassicaceae species, such as ''Brassica napus'', ''Brassica rapa'', ''Raphanus raphanistrum'', ''Barbarea vulgaris'' and ''Sinapis'' species). Taxonomy and phylogeny ''A. agilissima'' is a member of the order Hymenoptera, which includes wasps, bees, and ants. It is in the family Andrenidae, and the subfamily Andreninae. The genus ''Andrena'' is one of the largest genus of bees and comprises the sand or solitary mining bees. It was first listed under the Apis genera, but in 1775, Fabricus described this genus along with 14 other species. Most ''Andrena'' bees are solitary and a few are communal.

Andrena Vaga (Burgwald)
''Andrena vaga'', the grey-backed mining bee, is a species of solitary bee which is found in most of Europe but which is very rare in Great Britain, where it may be recolonizing in the south-east after previously being extirpated. It specialises in feeding on the pollen of willows. Description ''A. vaga'' is a large mining bee, 13-15mm in length, which has the entire thorax clothed in grey hairs, sometimes showing a slight buff tinge, the scopae and hind have white hairs.

Ashy Mining Bee
The ashy mining bee (''Andrena cineraria''), also known as the Danubian miner or grey mining bee, is a species of sand bee found in Europe. Its distinctive colouring makes it one of the most easily recognised of the genus. The females are black, with two broad grey hair bands across the thorax. The male is also black although the thorax is entirely covered with grey hairs. The male has a tuft of white hairs on the lower face and white hairs on all femora while the female has white hairs only on the front femora. The female has twelve segments to their antennae and the male has thirteen. The ashy mining bee is common and widespread throughout Europe, ranging from Ireland across central Europe and into Scandinavia. They are common throughout the United Kingdom although less frequent in northern Scotland. Generally docile, they are considered safe around children and pets. The ashy mining bee flies from April until early June, most noticeably during the flowering periods of fruit tre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andrena Antoinei
''Andrena antoinei'' is an extinct species of mining bee in the family Andrenidae described from a single fossil found in a Late Oligocene lake in present-day France that existed in semi-arid conditions. History and classification ''A. antoinei'' was described from a solitary fossil, which is a compression-impression fossil pair preserved in layers of soft sedimentary rock. Along with other well preserved insect fossils, the ''A. antoinei'' specimen was collected from layers of Late Oligocene lacustrine rock belonging to the "calcaire de Campagne Calavon" sediments. The material is exposed along the northern slopes of the Luberon mountains near Céreste in southern France. The sediments are reported as from a shallow paleolake that was formerly considered about 30 million year old and Rupelian in age. Recent restudy of formation has suggested the older Late Oligocene age. The paleoflora preserved in the shales suggest the lake was surrounded by a mixed-mesophytic forest, tho ...

Andrena Fulva
The tawny mining bee, ''Andrena fulva'', is a European species of the sand bee (''Andrena'') genus. The males are and the females long. The female is covered with fox-red hair on the dorsal surface of its thorax and abdomen and black hair on its head and ventral surface. The male is less distinctive, being clad in golden-brown or reddish-brown hairs, with some long white hairs on the face, and a tooth on each of the mandibles. The tawny mining bee lives in Europe, ranging from the Balkans to southern Scandinavia, the United Kingdom and Ireland. It lives among short vegetation in light woodlands and dry grasslands, and also in parks and gardens. It is widely distributed but has a low population density. It is present in lowland England and Wales and at a few sites in southern Scotland. In Ireland it was only known at two locations in County Kilkenny in 1927, and until 2012 was considered extinct, when it was rediscovered at several locations throughout Ireland. The tawny mining ...

Strepsiptera
The Strepsiptera are an order of insects with eleven extant families that include about 600 described species. They are endoparasites in other insects, such as bees, wasps, leafhoppers, silverfish, and cockroaches. Females of most species never emerge from the host after entering its body, finally dying inside it. The early-stage larvae do emerge because they must find an unoccupied living host, and the short-lived males must emerge to seek a receptive female in her host. They are believed to be most closely related to beetles, from which they diverged 300–350 million years ago, but do not appear in the fossil record until the mid-Cretaceous around 100 million years ago. The order is not well known to non-specialists, and the nearest they have to a common name is stylops. The name of the order translates to "twisted wing"', giving rise to other common names used for the order, twisted-wing insects and twisted-winged parasites. Adult males are rarely observed, although specimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
