Andrena Synadelpha
''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.

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Oligolecty
The term oligolecty is used in pollination ecology to refer to bees that exhibit a narrow, specialized preference for pollen sources, typically to a single family or genus of flowering plants. The preference may occasionally extend broadly to multiple genera within a single plant family, or be as narrow as a single plant species. When the choice is very narrow, the term ''monolecty'' is sometimes used, originally meaning a single plant species but recently broadened to include examples where the host plants are related members of a single genus. The opposite term is ''polylectic'' and refers to species that collect pollen from a wide range of species. The most familiar example of a polylectic species is the domestic honey bee. Oligolectic pollinators are often called oligoleges or simply specialist pollinators, and this behavior is especially common in the bee families Andrenidae and Halictidae, though there are thousands of species in hundreds of genera, in essentially all known b ...

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 ...

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 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 ...

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...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 ...
