Tetralonia Macroglossa
''Tetralonia malvae'', also known as the Mallow longhorn, is a species of insect belonging to the family Apidae. The bee takes pollen from oligolectic sources on the mallow family (Malvaceae). Behaviour They generally nest on bare or sparsely overgrown ground, even to heavily sloping surfaces, or in steep walls in self-dug corridors in the earth, often in aggregations. The preferred substrate is sand, loess or loess clay. The nest consists of a corridor that can branch out. The brood cells are more or less upright and are inside with a shiny layer coated. The species inhabits dry and warm locations; vineyards, fallow and ruderal areas, sand and clay pits, steep banks, from plains to the montane altitude level. Parasitism They are parasitised by the cuckoo bee species '' Triepeolus tristis''. Another nest parasite is a bladder-head fly of the genus ''Conops A concept of operations (abbreviated CONOPS, CONOPs, or ConOps) is a document describing the characteristics of a ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Loess
Loess (, ; from german: Löss ) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loess or similar deposits. Loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay and a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs. Properties Loess is homogeneous, porous, friable, pale yellow or buff, slightly coherent, typically non- stratified and often calcareous. Loess grains are angular, with little polishing or rounding, and composed of crystals of quartz, feldspar, mica and other minerals. Loess can be described as a rich, dust-like soil. Loess deposits may become very thick, more than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuckoo Bee
The term cuckoo bee is used for a variety of different bee lineages which have evolved the kleptoparasitism, kleptoparasitic behaviour of laying their eggs in the nests of other bees, reminiscent of the behavior of cuckoo birds. The name is perhaps best applied to the apidae, apid subfamily Nomadinae, but is commonly used in Europe to mean bumblebees ''List of bumblebee species, Bombus'' subgenus ''Psithyrus''. Females of cuckoo bees are easy to recognize in almost all cases, as they lack pollen collecting structures (the scopa (biology), scopa) and do not construct their own nests. They often have reduced body hair, abnormally thick and/or heavily sculptured exoskeleton, and saber-like mandible (insect), mandibles, although this is not universally true; other less visible changes are also common. They typically enter the nests of pollen-collecting species, and lay their eggs in cells provisioned by the host bee. When the cuckoo bee larva hatches it consumes the host larva's pollen ...

Triepeolus Tristis
''Triepeolus'' is a genus of cuckoo bees in the family Apidae. There are at least 140 described species in ''Triepeolus''.Sharkey M.J. (2007).

Conops
A concept of operations (abbreviated CONOPS, CONOPs, or ConOps) is a document describing the characteristics of a proposed system from the viewpoint of an individual who will use that system. Examples include business requirements specification or stakeholder requirements specification (StRS). CONOPS is used to communicate the quantitative and qualitative system characteristics to all stakeholders. CONOPS are widely used in the military, governmental services and other fields. A CONOPS generally evolves from a concept and is a description of how a set of capabilities may be employed to achieve desired objectives or end state. The first standard was ''1362-1998 - IEEE Guide for Information Technology - System Definition - Concept of Operations (ConOps) Document'' that was superseded by the document ''29148-2011 - ISO/IEC/IEEE International Standard - Systems and software engineering -- Life cycle processes --Requirements engineering''.
