Drone Fly
''Eristalis'' is a large genus of Hoverfly, hoverflies, family Syrphidae, in the order Diptera. Several species are known as drone flies (or droneflies) because they bear a resemblance to honeybee Drone (bee), drones. Drone flies and their relatives are fairly common generalist pollinators, the larvae of which are aquatic, and breathe through a long, Snorkeling, 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 sometim ... [...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 wingspa ...

Syrphus
''Syrphus'' is a genus of hoverflies. It can be distinguished from other genera of the tribe Syrphini because it is the only genus that has long hairs on the upper surface of the lower lobe of the calypter (as well as hairs on the rear margin of the calypter as in most Syrphini).

Georg Wolfgang Franz Panzer
Georg Wolfgang Franz Panzer (31 May 1755 – 28 June 1829) was a German botanist and entomologist. He was born at Etzelwang in the Upper Palatinate and died at Hersbruck, near Nuremberg. He was the son of (the elder, 1729-1805), one of the most distinguished and productive of German bibliographers, whose ''Annales Typographici'' were published between 1793 and 1803.G.W. Panzer, ''Annales Typographici ab Artis Inventae Origine usque ad annum MDXXXVI'', 11 Vols (Impensis Joannis Eberhardi Zeh, Bibliopolae, Norimbergae 1793-1803). A physician, he practised at Hersbruck. A celebrated botanist, he had a very species-rich herbarium. He also assembled a very important insect collection which was the basis of a vast work ''Faunae insectorum germanicae initia'' (Elements of the insect fauna of Germany), published at Nuremberg between 1796 and 1813. Illustrated by Jacob Sturm Jacob Sturm (21 March 1771 – 28 November 1848) was a leading engraver of entomological and botanical ...

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.

James Edward Collin
James Edward Collin (16 March 1876, Kirtling – 16 September 1968) was an English entomologist who specialised in Diptera. He was the author of ''Empididae''. ''British Flies'', Volume 6. University Press, Cambridge (1961). This was the third volume in an uncompleted series begun by his uncle George Henry Verrall. Collin wrote extensively on Diptera of most families of Diptera (excepting those in Nematocera). The specimens collected by Collin and his uncle Verrall are in the Hope Entomological Collections at the University of Oxford. The OUM website provides a searchable database of the new species they described. He was a Fellow of the Royal Entomological Society The Royal Entomological Society is devoted to the study of insects. Its aims are to disseminate information about insects and improving communication between entomologists. The society was founded in 1833 as the Entomological Society of Londo ... and its president 1927–1928. References *Chvála, M. 1970 ol ...

Halteres
''Halteres'' (; singular ''halter'' or ''haltere'') (from grc, ἁλτῆρες, weights held in the hands to give an impetus in leaping) are a pair of small club-shaped organs on the body of two orders of flying insects that provide information about body rotations during flight. Insects of the large order Diptera (flies) have halteres which evolved from a pair of ancestral hindwings, while males of the much smaller order Strepsiptera (stylops)Merriam-Webster: stylops broadly: an insect of the order Strepsiptera/ref> have halteres which evolved from a pair of ancestral forewings. Halteres oscillate rapidly along with the wings and operate like vibrating structure gyroscopes: any rotation of the plane of oscillation causes a force on the vibrating halteres by the Coriolis effect. The insect detects this force with sensory organs called campaniform sensilla and chordotonal organs located at the base of the halteres and uses this information to interpret and correct its posit ...
