Eristalis
''Eristalis'' is a large genus of hoverflies, family Syrphidae, in the order Diptera. Several species are known as drone flies (or droneflies) because they bear a resemblance to honeybee drones. Drone flies and their relatives are fairly common generalist pollinators, the larvae of which are aquatic, and breathe through a long, snorkel-like appendage, hence the common name rat-tailed maggots. ''Eristalis'' is a large genus of around 99 species, and is subdivided into several subgenera and species groups (''Eristalomyia'', ''Eristalis'', ''Eoseristalis'' etc.). Scientific name and grammatical gender The scientific name was proposed by Pierre André Latreille in 1804. He placed seven species in his new genus, but listed the names as combinations with ''Syrphus'', so it remained unclear what gender he attributed to the name (the gender of the name ''Syrphus'' is masculine). In the two centuries following its publication, ''Eristalis'' was sometimes considered to be of feminine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eristalis Tenax
''Eristalis tenax'', the common drone fly, is a common, migratory, cosmopolitan species of hover fly. It is the most widely distributed syrphid species in the world, and is known from all regions except the Antarctic. It has been introduced into North America and is widely established. It can be found in gardens and fields in Europe and Australia. It has also been found in the Himalayas. Distribution The larval form of the drone-fly, the rat-tailed maggot, is found on every continent except Antarctica, and ranges to the highest latitudes in the North. This species is not prevalent in extremely southern latitudes, neither is it common in arid areas of Europe, Asia, and Africa. In the United States, this species is found as far north as Alaska and as far south as California and Florida. Description ''Eristalis tenax'' is a large, stocky bee mimic. The eyes are marbled in black. Males have hovering displays. The average wing length is 9.75–13 mm and their average wing ...

Eristalis Alleni
Paul Allen's flower fly (''Eristalis alleni'') is a flower fly found only in Costa Rican forest in the central highlands. It was named after Paul Allen. Another fly was also named after Allen's associate Bill Gates, Bill Gates' flower fly (''Eristalis gatesi''). It is similar in appearance to ''Eristalis circe'' Williston, 1891 and ''Eristalis persa'' Williston, 1891, but has different leg colouration. Biology Little is known of its biology, but most adults are found in association with flowers in the genus ''Senecio ''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels.

Hoverfly
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mammals, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology Of Diptera
Dipteran morphology differs in some significant ways from the broader morphology of insects. The Diptera is a very large and diverse order of mostly small to medium-sized insects. They have prominent compound eyes on a mobile head, and (at most) one pair of functional, membraneous wings, which are attached to a complex mesothorax. The second pair of wings, on the metathorax, are reduced to halteres. The order's fundamental peculiarity is its remarkable specialization in terms of wing shape and the morpho-anatomical adaptation of the thorax – features which lend particular agility to its flying forms. The filiform, stylate or aristate antennae correlate with the Nematocera, Brachycera and Cyclorrhapha taxa respectively. It displays substantial morphological uniformity in lower taxa, especially at the level of genus or species. The configuration of integumental bristles is of fundamental importance in their taxonomy, as is wing venation. It displays a complete metamorphosis (egg, ...

Diptera
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
