Sphegina (subgenus)
''Sphegina'' is a genus of small, slender hoverflies. They are widespread throughout Eurasia and North America. In flight they seem to have long hind legs which they often carry hanging down, making them resemble sphecid or ichneumonid wasps. Adult ''Sphegina'' are usually found in damp and shady habitats close to water in forested areas, and several species can often be found together. They often feed on white and yellow flowers of Apiaceae, Ranunculaceae, Asteraceae, and Rosaceae like Crataegus, Sorbus, and Sorbaria. Larvae nest in the sap of living and dead trees or in decaying cambium under tree bark lying in water or other damp conditions. The larvae of some species have been discovered in the tunnels of other xylophagous insects. ''Sphegina'' generally have a face strongly concave and bare in both sexes, antennal basoflagellomere oval with a long dorsal and pilose arista; eyes bare and dichoptic in both sexes; postpronotum pilose; metasternum and katepisternum non-pilose ...

Sphegina Abbreviata
''Sphegina abbreviata'' is a species of hoverfly in the family Syrphidae found in Nepal. Like other species in its genus, ''S. abbreviata'' is small, slender, and usually found in and around woodlands. It's similar to '' S. angustata'', though it's differentiated by having both dorsal and ventral sublobes posteriorly on male superior lobe instead of just a dorsal one, and by having the dorsal sublobes be apically short and truncate instead of long and pointed. Etymology The name comes from Latin ‘abbreviata’, meaning ‘shortened’, referring to the unusually short abdomen. Description In male specimens, ''S. abbreviata'' has a body length of 4.6 millimeters and wing length of 4.7 millimeters. The occiput is brown; gena and mouth edge yellow; antennae dark brown, with black setae dorsally on scape and pedicel; thorax dark brown; scutellum dark brown and subtriangular; metafemur dark brown with basal ⅓ yellow, very weakly incrassate; metatibia dark brown and yellow bian ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Neoascia
These are small black and yellow or mostly black flies with a narrow abdomen near the thorax. They occur mainly in damp places among low herbage. The larva of ''Neosascia'' are flattened without oral hooks and a have a short posterior spiracular process or "tail" rat-tailed that is saprophagous. In 1925 Curran reviewed the genus ''Neoascia'' . In this work a key is provided and ten species are described including four new species some of which have later been determined to be synonyms.

Xylophagy
Xylophagy is a term used in ecology to describe the habits of an herbivorous animal whose diet consists primarily (often solely) of wood. The word derives from Greek ''ξυλοφάγος'' (''xulophagos'') "eating wood", from ''ξύλον'' (') "wood" and ''φαγεῖν'' (') "to eat", an ancient Greek name for a kind of a worm-eating bird. Animals feeding only on dead wood are called sapro-xylophagous or saproxylic. Xylophagous insects Most such animals are arthropods, primarily insects of various kinds, in which the behavior is quite common, and found in many different orders. It is not uncommon for insects to specialize to various degrees; in some cases, they limit themselves to certain plant groups (a taxonomic specialization), and in others, it is the physical characteristics of the wood itself (e.g., state of decay, hardness, whether the wood is alive or dead, or the choice of heartwood versus sapwood versus bark). Many xylophagous insects have symbiotic protozoa and/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambium
A cambium (plural cambia or cambiums), in plants, is a tissue layer that provides partially undifferentiated cells for plant growth. It is found in the area between xylem and phloem. A cambium can also be defined as a cellular plant tissue from which phloem, xylem, or cork grows by division, resulting (in woody plants) in secondary thickening. It forms parallel rows of cells, which result in secondary tissues. There are several distinct kinds of cambium found in plant stems and roots: * Cork cambium, a tissue found in many vascular plants as part of the periderm. * Unifacial cambium, which ultimately produces cells to the interior of its cylinder. * Vascular cambium, a lateral meristem in the vascular tissue of plants. Uses The cambium of many species of woody plants are edible; however, due to its vital role in the homeostasis and growth of woody plants, this may result in death of the plant if enough cambium is removed at once. The cambium can generally be eaten raw or cooke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' (''s.l.'') are commonly known as whitebeam, rowan ( mountain-ash) and service tree. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species.
