Acarinarium
An acarinarium is a specialized anatomical structure which is evolved to facilitate the retention of mites on the body of an organism, typically a bee or a wasp. The term was introduced by Walter Karl Johann Roepke. Evolution The acarinarium has evolved to enhance the Mutualism (biology), mutualistic relationship between the mites and the host organism. There are numerous cases where mites are phoresy, phoretic on organisms that benefit from the mites' presence; cases where the host's body has changed over evolutionary time to accommodate the mites are far less common. The best-known examples are among the Apocritan Hymenoptera, in which the hosts are typically nest-making species, and it appears that the mites feed on fungi in the host nests (thus keeping away the fungi from host's offspring or their provisions), or possibly other parasites or mites whose presence in the nest is detrimental to the hosts. It is especially telling that nearly all the examples involve only the femal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oligochlora
''Oligochlora'' is an extinct genus of sweat bee in the Halictidae subfamily Halictinae. The genus currently contains six species, all of which are known from the early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola. History and classification The genus was first described by Dr. Michael Engel in a 1996 paper published in the ''Journal of the Kansas Entomological Society''. The genus name is a combination of "Oligo", from Oligocene a possible age of the amber and "chlora" from the genus ''Augochlora'', the type genus of the tribe Augochlorini where ''Oligochlora'' is placed. Along with the genus description, the paper contained the description of the type species ''O. eickworti'' and the second species ''O. micheneri''. Dr Engel described a third species, ''O. grimaldii'' in 1997. A fourth species, ''O. rozeni'' was published in 2000 and the genus was split into two subgenera, ''Oligochlora'' (''Oligochlora'') and ''Oligochlora'' (''Soliapis' ...

Parancistrocerus
''Parancistrocerus'' is a rather large genus of potter wasps whose distribution spans the Nearctic, eastern Palearctic, Oriental and Neotropical regions. A pair of medial pits on the anterior face of the pronotum and the expansion of the tegulae put this genus close to the genus '' Stenodynerus'' and many species of both genera are somewhat difficult to assignate to their respective genus. Their species are notable for having a smooth depression acting as an acarinarium at the base of the second metasomal tergum and hidden under the first metasomal tergum. This acarinarium serves as shelter for symbiotic Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasit ... deutonymphs of mites in the family Winterschmidtiidae.

Mesotrichia
Carpenter bees are species in the genus ''Xylocopa'' of the subfamily Xylocopinae. The genus includes some 500 bees in 31 subgenera. The common name "carpenter bee" derives from their nesting behavior; nearly all species burrow into hard plant material such as dead wood or bamboo. The main exceptions are species in the subgenus '' Proxylocopa''; they dig nesting tunnels in suitable soil. Etymology The French entomologist Pierre André Latreille described the genus in 1802. He derived the name from the Ancient Greek ''xylokopos''/ξυλοκὀπος "wood-cutter". Characteristics Many species in this enormous genus are difficult to tell apart; most species are all black, or primarily black with some yellow or white pubescence. Some differ only in subtle morphological features, such as details of the male genitalia. Males of some species differ confusingly from the females, being covered in greenish-yellow fur. The confusion of species arises particularly in the common names; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phoresy
Phoresis or phoresy is a non-permanent, Commensalism, commensalistic interaction in which one organism (a phoront or phoretic) attaches itself to another (the host) solely for the purpose of travel. Phoresis has been observed directly in Acari, ticks and mites since the 18th century, and indirectly in fossils 320 million years old. It is not restricted to arthropods or animals; plants with seeds that disperse by attaching themselves to animals are also considered to be phoretic. ''Phoresis'' is rooted in the Greek words ''phoras'' (bearing) and ''phor'' (thief). The term, originally defined in 1896 as a relationship in which the host acts as a vehicle for its passenger, clashed with other terminology being developed at the time, so constraints on the length of time, feeding and ontogeny are now considered. Phoresis is used as a strategy for Biological dispersal, dispersal, Migration (ecology), seasonal migration, transport to new host/habitat escaping ephemeral habitats, ...

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.

Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potter Wasp
Potter wasps (or mason wasps), the Eumeninae, are a cosmopolitan wasp group presently treated as a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae. Recognition Most eumenine species are black or brown, and commonly marked with strikingly contrasting patterns of yellow, white, orange, or red (or combinations thereof), but some species, mostly from tropical regions, show faint to strong blue or green metallic highlights in the background colors. Like most vespids, their wings are folded longitudinally at rest. They are particularly recognized by the following combination of characteristics: # a posterolateral projection known as a parategula on both sides of the mesoscutum; # tarsal claws cleft; # hind coxae with a longitudinal dorsal carina or folding, often developed into a lobe or tooth, and; # fore wings with three submarginal cells. Biology Eumenine wasps are diverse in nest building. The different species may either use existi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Species
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...
