Syrphoidea
The Syrphoidea are a superfamily of flies containing only two families under present classification, one of which ( Syrphidae) has a great number of the most common and familiar flies. One of these familiar flies is ''Eristalis tenax ''Eristalis tenax'', the common drone fly, is a common, migratory, cosmopolitan species of hover fly.

Scaeva Pyrastri
''Scaeva pyrastri'', common name the pied hoverfly, is a species of hoverfly. Distribution These hoverflies are present in most of Europe, the Near East, the East Palearctic realm, the Nearctic realm, North Africa, and the Indomalayan realm. In the UK ''S. pyrastri'' is a migrant which arrives in some years in high numbers and in others is almost absent. Description ''Scaeva pyrastri'' can reach a length of . This large distinctive fly has three pairs of white comma markings ( lunules) on the abdomen, these are yellow on ''Scaeva selenitica''. The face is yellow, with reddish brown antennae. The eyes are covered with hair. Scutellum is brown yellow. The legs are red with a black base of the femur. The male's eyes do touch in the centre of the frons, while in the females they are separated. The larvae are light green or sometimes pink, with a white dorsal longitudinal stripe. Habitat and behavior This species can be found in gardens, meadows and wasteland. Adults are common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pipunculidae
Pipunculidae is a family of flies (Diptera) commonly termed big-headed flies, a reference to the large (holoptic) eyes, which cover nearly the entire head. The family is found worldwide and more than 1300 species have been described. The larvae of Pipunculidae develop as parasitoids almost exclusively in Auchenorrhyncha, the exception being the genus ''Nephrocerus'', whose hosts are adult Tipulidae (crane flies). The larvae develop rapidly within the crane flies before pupating in the soil. In all pipunculids there are only two larval stages. Some species are used as biological control agents in rice fields. Taxonomy Taxonomy as shown at the Tree of life, with modification based on Kehlmaier, Dierick and Skevington (2014). The name Pipunculidae is derived from the type genus ''Pipunculus'' which is thought to be derived from Latin ''pepo'' for pumpkin, thus pipunculus would mean "little pumpkin", referring to the large heads.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

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 ...
