Sphecodes Gibbus
''Sphecodes gibbus'', the dark-winged blood bee, is a species of cleptoparasitic blood bee from the Palearctic. It is the type species of the genus ''Sphecodes'' and was first described by Carl Linnaeus as ''Sphex gibba'' in 1758. Description ''Sphecodes gibbus'' is a relatively large ''Sphecodes'' species with a body length of around 10mm. Like other blood bees they are mainly black and red in colour. ''S. gibbus'' is one in three species of similar sized blood bees in which the females have punctures, instead of merely rugosity, to the posterior of the ocelli. The female ''S. gibbus'' may be separated from the similar '' S. monilicornis'' by its wider, less square shaped head, the darker pubescence on the hind tibiae and thinner propodeum. The broader zone of punctures to the rear of the ocelli allow separation from '' S. reticulatus'', ''S. gibbus'' having 5-6 irregular rows of punctures rather than the 2-3 shown by ''S. reticulatus'', as well as possessing sparser punctures ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ocelli
A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates. In this sense "simple eye" is distinct from a multi-lensed "compound eye", and is not necessarily at all simple in the usual sense of the word. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods. They possess a wide variety of novel solutions to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of humans and of other large animals such as most cephalopods, are ''camera eyes'' and ...

Halictus Simplex
The genus ''Halictus'' is a large assemblage of bee species in the family Halictidae. The genus is divided into 15 subgenera, some of dubious monophyly, containing over 200 species, primarily in the Northern Hemisphere (a few species occur in South America, Asia and Africa). Most species are black or dark brown, sometimes metallic greenish-tinted, with apical whitish abdominal bands on the terga (the related genus ''Lasioglossum'', which is otherwise often similar in appearance, has the abdominal hair bands located basally, not apically). Many species in the genus are eusocial, with colony sizes range from very small (two to four bees) to large (>200). Nests are typically burrows in the soil, with several ovoid "cells" in which pollen mixed with nectar is provided as food for the developing larvae; a single egg is laid on a pollen mass, and the cell is sealed. In a few species, the cells are arranged in clusters resembling a honeycomb, but constructed of soil rather than bees ...

Halictus Sexcinctus
''Halictus sexcinctus'', commonly referred to as the six-banded furrow bee, is a species of sweat bee found throughout Europe and as far east as Asian Turkey and Iraq.The ''H. sexcinctus'' can be easily confused with the closely related species, ''Halictus scabiosae'', due to very similar morphological features. ''H. sexcinctus'' show a social polymorphism in which different colonies can exhibit solitary, communal, or eusocial structure. Due to this large variance in social organization, it was suspected that it was not one species at all, but rather multiple, cryptic species. However, genetic analysis was able to confirm these varying populations as one species. ''H. sexcinctus'' will forage from multiple flower species, but prefers plant species with wide-open flowers. Their nests can be found dug into the ground in loamy or sandy soil. Taxonomy and phylogenetics ''Halictus sexcinctus'' is part of the family Halictidae, which are commonly referred to as the sweat bees. Species ...

Halictus Rubicundus
''Halictus rubicundus'', the orange-legged furrow bee, is a species of sweat bee found throughout the Northern Hemisphere. ''H. rubicundus'' was introduced into North America from the Old World during one of two main invasions of ''Halictus'' subgenera. These invasions likely occurred via the Bering land bridge at times of low sea level during the Pleistocene epoch. The species exhibits different social behaviors depending on climate: it is a solitary species in high elevations or latitudes where the season is short, but eusocial in other areas. Often, solitary and eusocial colonies appear simultaneously in the same population. These sweat bees are extensively studied for their variability in social behavior, which has become a model for social plasticity. This variability has contributed to an understanding of evolution of social behavior.Yanega, D. (1997) Demography and sociality in halictine bees (Hymenoptera: Halictidae). pp. 293-315 in Choe, J.C. & Crespi, B.J. (eds.) Socia ...

Lasioglossum
The sweat bee genus ''Lasioglossum'' is the largest of all bee genera, containing over 1700 species in numerous subgenera worldwide.Gibbs, J., et al. (2012)Phylogeny of halictine bees supports a shared origin of eusociality for ''Halictus'' and ''Lasioglossum'' (Apoidea: Anthophila: Halictidae).''Molecular Phylogenetics and Evolution'' 65(3), 926-39. They are highly variable in size, coloration, and sculpture; among the more unusual variants, some are cleptoparasites, some are nocturnal, and some are oligolectic. Most ''Lasioglossum'' species nest in the ground, but some nest in rotten logs. Social behavior among species of ''Lasioglossum'' is extraordinarily variable; species are known to exhibit solitary nesting, primitive eusociality, and social parasitism. Colony sizes vary widely, from small colonies of a single queen four or fewer workers to large colonies of >400 workers and perennial life cycles. The genus ''Lasioglossum'' can be divided ...

Mongolia
Mongolia; Mongolian script: , , ; lit. "Mongol Nation" or "State of Mongolia" () is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of , with a population of just 3.3 million, making it the world's most sparsely populated sovereign nation. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population. The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous land empire in history. His grandson Kublai Khan conquered China proper and established the Yuan dynasty.

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Tergite
A ''tergum'' (Latin for "the back"; plural ''terga'', associated adjective tergal) is the dorsal ('upper') portion of an arthropod segment other than the head. The anterior edge is called the 'base' and posterior edge is called the 'apex' or 'margin'. A given tergum may be divided into hardened plates or sclerites commonly referred to as tergites. In a thoracic segment, for example, the tergum may be divided into an anterior notum and a posterior scutellum. Lateral extensions of a tergite are known as paranota (Greek for "alongside the back") or ''carinae'' (Latin for "keel"), exemplified by the flat-backed millipedes of the order Polydesmida. Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods. Tergo-tergal is a stridulatory mechanism in which fine spines of the abdominal tergites are rubbed together to produce sound. This process is known as abdominal telescoping.
