Osirini
The Osirini are a tribe of cleptoparasitic apid bees, all but one genus exclusively from the Neotropics, and laying their eggs in the nests of bees in the apid tribe Tapinotaspidini; the one exceptional genus is ''Epeoloides'', which has one North American species and one European species, both of which attack the melittid genus ''Macropis''. All species in this tribe are unique among the bees in the possession of a tiny sclerite A sclerite (Greek , ', meaning "hard") is a hardened body part. In various branches of biology the term is applied to various structures, but not as a rule to vertebrate anatomical features such as bones and teeth. Instead it refers most commonly ... embedded in the membrane beneath the head, possibly to help guard against being stung in the neck by an angry host bee when invading a nest. References * C. D.

Apinae
The Apinae are the subfamily that includes the majority of bees in the family Apidae. It includes the familiar " corbiculate" (pollen basket) bees—bumblebees, honey bees, orchid bees, stingless bees, Africanized bees, and the extinct genus ''Euglossopteryx''. It also includes all but two of the groups (excluding Nomadinae and Xylocopinae) that were previously classified in the family Anthophoridae. Most species in the subfamily (other than honey bees, bumblebees, and stingless bees) are solitary, though several of the tribes are entirely kleptoparasitic, such as the Ericrocidini, Isepeolini, Melectini, Osirini, Protepeolini, and Rhathymini. Behaviors Certain behaviors are known from members of the Apinae that are rarely seen in other bees, including the habit of males forming "sleeping aggregations" on vegetation - several males gathering on a single plant in the evening, grasping a plant with their jaws and resting there through the night (sometimes held in place only by ...

Macropis
''Macropis'' is a genus of bees in the family Melittidae. Description ''Macropis'' species are of moderate size, not exceeding 15 mm. They have a livery predominantly black; males are characterized by conspicuous yellow markings on the head, but the females show morphological adaptations related to their foraging habits of flower oils, posterior tibiae with very developed, covered with a dense velvety hairs. Unlike most Melittidae, the wing has only two submarginal cells. Biology They are solitary bees that dig their nests in the ground. Most species are oligolectic and feed on pollen and floral oils of ''Lysimachia'' spp. They make a single generation per year. The males emerge from the ground in spring, just before the females, and await the females in the vicinity of the flowers of the host plant. After mating, the females dig a nest in the ground, ending with one or two rooms in which is collected the pollen, which is placed on the egg. The larvae, feeding on the poll ...

Apidae
Apidae is the largest family within the superfamily Apoidea, containing at least 5700 species of bees. The family includes some of the most commonly seen bees, including bumblebees and honey bees, but also includes stingless bees (also used for honey production), carpenter bees, orchid bees, cuckoo bees, and a number of other less widely known groups. Taxonomy In addition to its historical classification (honey bees, bumble bees, stingless bees and orchid bees), the family Apidae presently includes all the genera formerly placed in the families Anthophoridae and Ctenoplectridae. Although the most visible members of Apidae are social, the vast majority of apid bees are solitary, including a number of cleptoparasitic species. The old family Apidae contained four tribes (Apinae: Apini, Euglossini and Bombinae: Bombini, Meliponini) which have been reclassified as tribes of the subfamily Apinae, along with all of the former tribes and subfamilies of Anthophoridae and the former f ...

Osiris (genus)
The cleptoparasitic bee genus ''Osiris'' is a rare group of apid bees from the Neotropics (Mexico through Argentina), that lay their eggs in the nests of bees in the related tribe Tapinotaspidini, such as '' Paratetrapedia''. Most of the known species are pale yellowish, smooth and shining, and very wasp-like in appearance. Females in this tribe are unusual in having the last metasomal sternite elongated to form a sheath for the sting Sting may refer to: * Stinger or sting, a structure of an animal to inject venom, or the injury produced by a stinger * Irritating hairs or prickles of a stinging plant, or the plant itself Fictional characters and entities * Sting (Middle-eart ..., which is remarkably long.

Cleptoparasite
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] |
Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Neotropics
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropics, tropical Ecoregion#Terrestrial, terrestrial ecoregions of the Americas and the entire South American temperate climate, temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Phytochorion, Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic Floristic Kingdom, Antarctic kingdom. The ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.
