Platypezoidea Genera
The Platypezoidea are a superfamily of true flies of the section Aschiza. Their closest living relatives are the Syrphoidea, which, for example, contain the hoverflies. Like these, the adults do not burst open their pupal cases with a ptilinum when hatching, thus the Aschiza do not have the inverted-U-shaped suture above the antennae. They are, however, muscomorphs, thus have a particular type of pupal case resembling a rounded barrel and called puparium. Families Five families are placed in the Platypezoidea, listed below in taxonomic sequence: * Phoridae - coffin and scuttle flies (includes Sciadoceridae) * Opetiidae - flat-footed flies * Ironomyiidae - ironic flies * Lonchopteridae - spear-winged flies, pointed-wing flies * Platypezidae Platypezidae is a family (biology), family of Fly, true flies of the Taxonomic rank, superfamily Platypezoidea. The more than 250 species are Cosmopolitan distribution, found worldwide primarily in woodland habitats. A common name is ...

Pseudacteon
''Pseudacteon'' is a genus of flies in the family Phoridae. There are over 70 described species of ''Pseudacteon'' fly. They are also known as ant-decapitating flies due to their parasitic larval stage. An egg is injected by the female fly into the shoulder joint of an ant worker. Soon after, the egg undergoes rapid inflation as it appears to absorb ant hemolymph. This first instar larva migrates into the ant head and consumes the jaw muscle and other tissues, leaving the mandibles hanging and preparing a future exit space. After about two weeks, the ant worker is termed a "zombie" because the fly larva has effectively taken control. The worker leaves the nest and dies in the leaf litter or in a crack in the soil. As it dies, the ant's head falls off, apparently because the fly larva releases an enzyme that dissolves the membrane attaching the ant's head to its body. The fly pupates in the detached head capsule, requiring a further two weeks before emerging through the ant's mouth. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ptilinum
The ptilinum is an eversible pouch on the head, above the base of the antenna in schizophoran flies (a section Section, Sectioning or Sectioned may refer to: Arts, entertainment and media * Section (music), a complete, but not independent, musical idea * Section (typography), a subdivision, especially of a chapter, in books and documents ** Section sig ... of muscomorphan and cyclorrhaphan flies). It is used to force off the end of the puparium in order for the fly to emerge, and after this inflation at emergence, the ptilinum collapses back inside the head, marked thereafter only by the ptilinal suture or frontal suture (which defines the aperture through which it everts).

Platypezidae
Platypezidae is a family (biology), family of Fly, true flies of the Taxonomic rank, superfamily Platypezoidea. The more than 250 species are Cosmopolitan distribution, found worldwide primarily in woodland habitats. A common name is flat-footed flies, but this is also used for the closely related Opetiidae which were included in the Platypezidae in former times. Some other genera formerly included here have been recognized as quite more distant and are nowadays placed in the Asilomorpha, asilomorph family Atelestidae. Description For terms see Morphology of Diptera. Platypezidae are minute to medium sized (1.5–6 mm) slender or robust flies. The male and female usually differ in colour. Males in particular are often all black, one or both sexes may be in part or all grey or yellow. Markings may be orange, grey or silver. The abdomen may have two colours. Males have holoptic eyes. The antenna has three segments, the third is the largest and bears a long, apical arista ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lonchopteridae
The Lonchopteridae (spear-winged flies or pointed-wing flies) are a family of small (2–5 mm), slender, yellow to brownish-black Diptera, occurring all over the world. Their common name refers to their pointed wings, which have a distinct venation. Many are parthenogenic; males are very rare, however, at least in North American species, and have a somewhat different venation than do the females.Smith, K.G.V. (1969): '' Handbook for the Identification of British Insects'' 10(2ai: Diptera Lonchopteridae): 1–9.Borror, D.J.; Triplehorn, C.A. & Johnson, N.A. (1989): ''An Introduction to the Study of Insects'' (6th edition). Saunders College Publishing. Spear-winged flies are common in moist, shady, grassy areas, where the larvae are found within decaying vegetation. One species, ''Lonchoptera bifurcata'', is cosmopolitan in distribution, and may have been transported via shipments of vegetables. Description For terms see Morphology of Diptera.

Ironomyiidae
Ironomyiidae is a small family of flies in the order Diptera. Historically, they had been included in the family Platypezidae, and includes three extant species within the single extant genus ''Ironomyia'' endemic to Australia and a number of extinct fossil genera from North America and Asia extending back to the Early Cretaceous.

Opetiidae
The Opetiidae or flat-footed flies are members of a family of flies (insects of the Order Diptera). The family contains only five extant species in two genera, '' Opetia'' from the Palearctic region and '' Puyehuemyia'' from Chile in South America. Several fossil genera have been assigned to the family, but many of these are likely to belong elsewhere in the Platypezoidea. '' Lonchopterites'' from the Early Cretaceous Lebanese amber and '' Electrosania'' from the Late Cretaceous New Jersey amber seem likely to be closely related to modern opetiids.

Muscomorpha
The Brachyceran infraorder Muscomorpha is a large and diverse group of flies, containing the bulk of the Brachycera, and, most of the known flies. It includes a number of the most familiar flies, such as the housefly, the fruit fly, and the blow fly. The antennae are short, usually three-segmented, with a dorsal arista. Their bodies are often highly setose, and the pattern of setae is often taxonomically important. The larvae of muscomorphs (in the sense the name is used here; see below) have reduced head capsules, and the pupae are formed inside the exoskeleton of the last larval instar; exit from this puparium is by a circular line of weakness, and this pupal type is called "cyclorrhaphous"; this feature gives this group of flies their traditional name, Cyclorrhapha. Classification The name Cyclorrhapha is used, in various modern classifications, to represent either a subgroup within the infraorder Muscomorpha, or simply a rankless group within the Brachycera.

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...

Pupa
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...

Phoridae
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking to the wing. This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to '' Conicera tibialis''. About 4,000 species are known in 230 genera. The most well-known species is cosmopolitan ''Megaselia scalaris''. At 0.4 mm in length, the world's smallest fly is the phorid ''Euryplatea nanaknihali''. Description For terms see Morphology of Diptera Phorid flies are minute or small – 0.5–6 mm (– in) in length. When viewed from the side, a pronounced hump to the thorax is seen. Their colours range from usually black or brown to more rarely yellow, orange, pale grey, and pale white. The head is usually rounded and in some species narrowed towards the vertex. The vertex is flat. In some species, the ocellar callus i ...

Hoverflies
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 mamma ...
