Mydidae is one of the smaller families of Diptera, with 471 species currently described in 66 genera world-wide.Mydids are infrequently collected, so little is known about the life history and seasonality of these interesting flies. The wings are long, and narrow to wide. Mydas heros). III. [3][4], The oldest known member of the family is Cretomydas from the Early Cretaceous (Aptian) Crato Formation of Brazil.

Synopsis and Classification of Living Organisms.

Keywords: Diptera, Mydidae, Syllegomydinae, Namadytes, Afrotropical Region, taxonomy. The abdomen is long and cylindrical in section. The genus appears to have close affinites to the subfamily Diochlistinae, suggesting a Cretaceous diversification for the family.[5]. Adults of several species are avid flower visitors and act as pollinating agents. (1993). The adults are most commonly encountered in sand dune areas, and are typically only active for a few weeks each year, either in the spring or the fall; in some cases, more than one species can occur in the same dune system, but they are allochronic, each flying in different seasons.

The group is widespread geographically and was probably originated while landmasses were still united forming the Pangea ( Papavero & Wilcox, 1974 ; Artigas & Papavero, 1990 ; Yeates & Irwin, 1996 ). It is slightly tapered apically in the male, and usually widest at segment four in the female.

Diptera family Mydidae Name Synonyms Mydaidae Homonyms Mydidae Common names mydas flies in language. 2 volumes. By Nelson Papavero, Therezinha Pimentel and José Albertino Rafael. The Mydidae (sometimes misspelled as Mydaidae), or Mydas flies, are a cosmopolitan family of flies.It is a small family, with about 471 species described. The hind leg is much longer and stronger than both the middle leg and the fore leg and the hind femur is usually swollen and bears ventral spines. McGraw-Hill, New York. [2], The classification of the family has changed fairly recently, with the inclusion of a few genera that were previously placed in the family Apioceridae.

These habitats are heavily targeted for development, and even if not, activities such as sand mining or motorized off-roading are common, and render the habitat unsuitable for the survival of the flies.

These 63 genera belong to the family Mydidae: Data sources: i = ITIS,[6] c = Catalogue of Life,[7] g = GBIF,[8] b = Bugguide.net[9], "The American genera of Mydidae (Diptera) with the description of three new genera and two new species", "Studies of Mydidae (Diptera) systematics and evolution.

and can be found in standing and downed trees with extensive heart rot.

While there is only one of these on the Endangered Species List (Rhaphiomidas terminatus abdominalis, a.k.a. Chapman & Hall, London, 845 pp. The Fossil Record 2. Mydas heros).Many of the species, in addition to their large size, are mimics of stinging hymenopterans, especially wasps.Most mydids are found in arid and semiarid … The second segment of the antenna forms a club. Teskey, H. J.,McAlpine, J. F.,Wilcox, J.,Shewell, G. E.,Wood, D. M.,Vockeroth, J. R.,Peterson, B. V. (1981) Chapter 40. The restriction to sand dune areas has unfortunately led a number of these flies to the brink of extinction, especially both subspecies of R. terminatus, and the species R. trochilus. They are infrequently encountered as the adult lifespan can be quite short. The seminal work by Hesse (1969) on the southern African mydids based primarily on specimens he collected himself throughout western South Africa, in which he described no fewer …

Mydas maculiventris) are subterranean and feed on "white grubs" (Scarabaeidae: genus Phyllophaga) that attack the roots of grasses and could be potential biocontrol agents of white grubs in sod production areas.

Abstract. [1] They are generally large in size, including the largest known fly, Gauromydas heros (syn. http://creativecommons.org/licenses/by-nc/4.0/, http://creativecommons.org/licenses/by/4.0/. Mydidae. Most of the veins end in the upper margin before the apex. Among the genera transferred is Rhaphiomidas, which includes one of the few Diptera on the United States' Endangered Species List, the Delhi Sands flower-loving fly (Rhaphiomidas terminatus abdominalis). (1982).

The mydid fly genus Rhaphiomidas contains fewer than 30 species/subspecies, all of them occurring in the desert regions of the southwestern United States and adjacent portions of northwestern Mexico.

The Mydidae (sometimes misspelled as Mydaidae), or Mydas flies, are a cosmopolitan family of flies.

Most mydids are found in arid and semiarid regions of the world,[1] but they are also found in other habitats.
The adults are most commonly encountered in … The southern African Mydidae fauna is the most diverse world-wide both in terms of species numbers and generic diversity.

It is a small family, with about 471 species described. We’re sorry, but GBIF doesn’t work properly without JavaScript enabled. Almost nothing is known about their biology, though eggs or early instar larvae of some species are laid on the soil surface and appear to be attractive to ants, and are brought into the ant nest (it therefore seems likely that the larvae are predators of the ant brood). Benton, M.J. (ed). larvae. Mydids are sparsely pilose, and lack bristles except on the legs. Rattlesnake master (Eryngium yuccifolium) is a favorite nectar source in the Midwest.

(ed). the "Delhi Sands Flower-loving fly"), many of the remaining taxa - including a few that have not yet been named - are gravely imperiled, as they are restricted to small geographic areas (less than 500 square miles (1,300 km2), sometimes much less), rendering them extremely vulnerable to habitat loss or disturbance. Apiocerids have long been given the common name "flower-loving flies", but only the group of "flower-loving flies" that actually visit flowers were transferred to the Mydidae. Little is known about their biology, though Zikan reported the larvae of Gauromydas heros live in the subterranean detritus "pans" of Atta ants in southern Brazil, where they appear to be feeding on detritivorous Dynastinae (Coelosis spp.) They are generally large in size, including the largest known fly, Gauromydas heros (syn. Parker, S.P.

The mydid fly genus Rhaphiomidas contains fewer than 30 species/subspecies, all of them occurring in the desert regions of the southwestern United States and adjacent portions of northwestern Mexico. Many of the species, in addition to their large size, are mimics of stinging hymenopterans, especially wasps. The family affiliation of the genus has changed fairly recently, as it had been previously placed in the family Apioceridae, or "flower-loving flies" - but, despite the transfer, the name "flower-loving flies" is nonetheless still used to refer to various species of Rhaphiomidas.



Current knowledge of the Mydidae fauna indicates that most of the species diversity occurs in the Afrotropical Region, specifically in Namibia and western South Africa. Mydids are medium-sized to very large flies (9–60 mm in body length). Larvae typically take two or three years to mature. These 28 species belong to the genus Rhaphiomidas.
