Andrena Barbilabris
''Andrena barbilabris'', the bearded miner bee, is a species of miner bee in the family Andrenidae. It is found in Europe and Northern Asia (excluding China) and North America. Description The bearded miner bee is commonly around 11 mm in length, the males being smaller and slenderer than the females. The females have rufous hairs on the dorsal surface of the thorax which contrast with the yellower hairs on its sides and head. The males can appear silvery in colour because of the long pale hairs on their thorax. The integument is largely black. It has a narrow head which gives this species a rather hunch-backed appearance. Distribution The bearded miner bee has a Holarctic distribution, being found across North America in southern Canada and the northern United States. In Eurasia it is distributed from western Europe to Anatolia, into western and eastern Siberia to the Russian Far East in Yakutia and Primorsky Krai and in Japan. In Britain and Ireland it has a patchy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Kirby (entomologist)
William Kirby (19 September 1759 – 4 July 1850) was an English entomologist, an original member of the Linnean Society and a Fellow of the Royal Society, as well as a country rector, so that he was an eminent example of the "parson-naturalist". The four-volume ''Introduction to Entomology'', co-written with William Spence, was widely influential. Family origins and early studies Kirby was a grandson of the Suffolk topographer John Kirby (author of ''The Suffolk Traveller'') and nephew of artist-topographer Joshua Kirby (a friend of Thomas Gainsborough's). He was also a cousin of the children's author Sarah Trimmer. His parents were William Kirby, a solicitor, and Lucy Meadows. He was born on 19 September 1759 at Witnesham, Suffolk, and studied at Ipswich School and Caius College, Cambridge, where he graduated in 1781. Taking holy orders in 1782, he spent his entire working life in the peaceful seclusion of an English country parsonage at Barham in Suffolk, working at th ...

Yakutia
Sakha, officially the Republic of Sakha (Yakutia),, is the largest republic of Russia, located in the Russian Far East, along the Arctic Ocean, with a population of roughly 1 million. Sakha comprises half of the area of its governing Far Eastern Federal District, and is the world's largest country subdivision, covering over 3,083,523 square kilometers (1,190,555 sq mi).

Andrena Sp
''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 dist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sphecodes
''Sphecodes'' is a genus of bees from the family Halictidae, the majority of which are black and red in colour and are colloquially known as blood bees. ''Sphecodes'' bees are kleptoparasitic on other bees, especially bees in the genera ''Lasioglossum'', ''Halictus'' and ''Andrena''. The adults consume nectar, but because they use other bees' provisions to feed their offspring they do not collect pollen. Distribution ''Sphecodes'' is a cosmopolitan genus with species represented on every continent. The genus is also very species rich, with 21 species described from Siberia, 33 species from Central Europe, 17 species from the Indian region, 26 from the Arabian Peninsula and surrounding region, and 21 from Southeast Asia. The genus is only represented in Australia in the northeast, with the species ''Sphecodes albilabris'' being thought to have been introduced to both Australia and the United States by accident. Species There are over 300 known species in the genus ''Sphecodes''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kleptoparasitism
Kleptoparasitism (etymologically, parasitism by theft) is a form of feeding in which one animal deliberately takes food from another. The strategy is evolutionarily stable when stealing is less costly than direct feeding, which can mean when food is scarce or when victims are abundant. Many kleptoparasites are arthropods, especially bees and wasps, but including some true flies, dung beetles, bugs, and spiders. Cuckoo bees are specialized kleptoparasites which lay their eggs either on the pollen masses made by other bees, or on the insect hosts of parasitoid wasps. They are an instance of Emery's rule, which states that insect social parasites tend to be closely related to their hosts. The behavior occurs, too, in vertebrates including birds such as skuas, which persistently chase other seabirds until they disgorge their food, and carnivorous mammals such as spotted hyenas and lions. Other species opportunistically indulge in kleptoparasitism. Strategy Kleptoparasitism is a fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nectar
Nectar is a sugar-rich liquid produced by plants in glands called nectaries or nectarines, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide herbivore protection. Common nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds, honeyeaters and bats. Nectar plays a crucial role in the foraging economics and evolution of nectar-eating species; for example, nectar foraging behavior is largely responsible for the divergent evolution of the African honey bee, ''A. m. scutellata'' and the western honey bee. Nectar is an economically important substance as it is the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, a number of parasitoid wasps (e.g. the social wasp species ''Apoica flavissima'') rely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jersey
Jersey ( , ; nrf, Jèrri, label=Jèrriais ), officially the Bailiwick of Jersey (french: Bailliage de Jersey, links=no; Jèrriais: ), is an island country and self-governing Crown Dependencies, Crown Dependency near the coast of north-west France. It is the largest of the Channel Islands and is from the Cotentin Peninsula in Normandy. The Bailiwick consists of the main island of Jersey and some surrounding uninhabited islands and rocks including Les Dirouilles, Écréhous, Les Écréhous, Minquiers, Les Minquiers, and Pierres de Lecq, Les Pierres de Lecq. Jersey was part of the Duchy of Normandy, whose dukes became kings of England from 1066. After Normandy was lost by the kings of England in the 13th century, and the ducal title surrendered to France, Jersey remained loyal to the The Crown, English Crown, though it never became part of the Kingdom of England.

Guernsey
Guernsey (; Guernésiais: ''Guernési''; french: Guernesey) is an island in the English Channel off the coast of Normandy that is part of the Bailiwick of Guernsey, a British Crown Dependency. It is the second largest of the Channel Islands, an island group roughly north of Saint-Malo and west of the Cotentin Peninsula. The jurisdiction consists of ten parishes on the island of Guernsey, three other inhabited islands ( Herm, Jethou and Lihou), and many small islets and rocks. It is not part of the United Kingdom, although defence and some aspects of international relations are managed by the UK. Although the bailiwicks of Jersey and Guernsey are often referred to collectively as the Channel Islands, the "Channel Islands" are not a constitutional or political unit. Jersey has a separate relationship to the Crown from the other Crown dependencies of Guernsey and the Isle of Man, although all are held by the monarch of the United Kingdom. The island has a mixed British-Norm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
