The genus Dolichopus is the most speciose, with some species. Dolichopodidae generally are small flies with large, prominent eyes and a metallic cast to their appearance, though there is considerable variation among the species. Most have long legs, though some do not. In many species the males have unusually large genitalia which are taxonomically useful in identifying species. Most adults are predatory on other small animals, though some may scavenge or act as kleptoparasites of spiders or other predators. An expanded The Long-Legged Fly of the family Dolichopodidae sensu lato includes the subfamilies Parathalassiinae and Microphorinae. The latter of these was formerly placed in the Empididaeand was at one time considered a separate family Microphoridae. For clarification of technical terms see Morphology of Diptera. Dolichopodidae are a family of flies ranging in size from minute to medium-sized 1mm to 9mm. They have characteristically long and slender legs, though their leg length is not as striking as in families such as the Tipulidae. The Long-Legged Fly posture often is stilt-like standing high on their legs, with the body almost erect. In colour most species have a green-to-blue metallic lustre, but various other species are dull yellow, brown or black. The frons in both sexes is broad. The eyes are separated on the frons of males, except in some species of Diaphorus and Chrysotus in which eyes touch above the antennal insertion. The face of some species The Long- Legged Fly entire; in others it is divided into two sections: the epistoma and the clypeus. The largest antennal segment is the third; in most species it bears a long arista, which is apical in some species, dorsal in others. In most species the mouthparts are short and have a wide aperture as an adaptation for sucking small prey. The legs are gracile and the tibiae usually bear long bristles. In some genera the legs are raptorial. In some species the tibiae of the males have modifications. The wings of most The Long-Legged Fly are clear or tinged, but some species have wings that are patterned in strong colours or with distinct spots. The anterior cross-vein is in the basal part of the wing. The posterior The Long- Legged Fly wing cell and the discoidal wing cell are always fused. The anal cell of the wing is always small. There are two veins branching from cross-vein DM-Cu in the direction of the The Long-Legged Fly margin; the upper one in some species curves strongly or forks into M 1 and M 2. The point of origin of R s is at or very close to h. The abdomen is elongate-conical or flat. The genitalia of the male often are free and borne on a petiole, The Long-Legged Fly tergite 8 being The Long-Legged Fly, lying on the left side of the epandrium. The gonopods may fuse with The Long-Legged Fly epandrium in genera such as HydrophorusThrypticus and Argyraor there may be a suture, as in the genera PorphyropsXiphandrium and Rhaphium. In some genera, such as Hypophyllus and Tachytrechusthe surstyli are well-developed as secondary outgrowths of the epandrium. In genera such as Tachytrechusthere are two pairs of surstyli—one proximal and one distal. The hypandrium in most species is a small sclerite, which may be asymmetrical as in the genera Porphyrops and Tachytrechus. Males of many species have highly developed cerci. Development of the phallus varies considerably between genera. Adults of the Dolichopodidae live largely in grassy places and shrubbery. The flies occur in a wide range of habitats, near water or in meadows, woodland edges and in gardens. Some groups are confined to wet places including sands on the banks of water bodies; examples include genera such as PorphyropsTachytrechusCampsicnemusand Teuchophorus. No truly aquatic species The Long-Legged Fly been described, but many are semi-aquatic and live in or near water margins. A small number of species develop on the shores of saline inland bodies of water or the intertidal zone of seashores. An example of a species that develop close to water is P. Other groups are found on trunks of trees damaged by bark beetles. Adults often are seen in a characteristic predatory posture standing high on their legs on the ground or on The Long-Legged Fly, tree trunks or rocks, and some species walk about on the surface of still The Long-Legged Fly. The adults are predators, feeding on small The Long-Legged Fly including Collembolaaphidsand the larvae of Oligochaeta. Species of the genus Dolichopus commonly prey on The Long-Legged Fly larvae of mosquitoes. The larvae occupy a wide range of habitats. Many are predators of small invertebrates and generally live in moist environments The Long-Legged Fly as soil, moist sand, or rotting organic The Long-Legged Fly. Genera such as Medetera live as predators under tree bark or in the tunnels of bark beetles. Larvae of the genus Thrypticus are unusual among Dolichopodidae, in that they are phytophagous and live in the stems of reeds and other monocots near water. Many studies have shown that Dolichopodidae give visual, rather than chemical or other signals during courtship. These characters include flaglike flattening of the arista and tarsi, strongly modified setae and projections of the tarsi, the prolongation and deformation of podomeres, orientated silvery pruinosity, and maculation or modification of the wings. Dolichopodids are well represented in amber deposits throughout the world and the group has clearly been well distributed since the Cretaceous at the latest. Together with the Empididae they are the most advanced members of the Empidoidea. They represent the bulk of Empidoidea diversity, and include more than two-thirds of the known species in their superfamily. Taxonomic interrelationships within the Dolichopodidae, and their delimitation from the Empididae, are not yet satisfactorily resolved. It is likely that many of the subfamilies currently within the The Long-Legged Fly will undergo drastic revision. Based on the most The Long-Legged Fly phylogenetic studies, the relationship between Dolichopodidae and other members of Empidoidea is as follows.
