The Micropezidae are a moderate-sized family of acalyptrate muscoid flies in the insect order Diptera, comprising about 500 species in about 50 genera and five subfamilies worldwide, (except New Zealand and Macquarie Island).[1] They are most diverse in tropical and subtropical habitats, especially in the Neotropical Region.

Insects in this family are commonly called stilt-legged flies, after their characteristically long legs. The fore legs are markedly smaller than the other pairs. Mostly, they are long-bodied, often black flies, usually with infuscated (darkened) wings. Wings are reduced in the genera Calycopteryx and entirely absent in the ant-like Badisis ambulans.[1]

Description

For terms see Morphology of Diptera
Very slender, small to large (3–16 mm) flies, they have long, thin legs and narrow wings. The head is small and elongated or rounded. The antennae are small and the arista is bare or pubescent. Ocelli are present, but ocellar bristles are absent. Vibrissae are absent and the postvertical bristles are divergent or absent. Up to three pairs of frontal bristles curve forward or backward. Interfrontal bristles are absent. The wings are clear or have a smoky pattern. The costa is without interruptions. The subcosta is complete, its ending in the costa close to vein R1. The posterior basal wing cell and discoidal wing cell are sometimes fused. Crossvein BM-Cu present or (Micropezinae) absent. The abdomen is long and narrow. The tibiae lack a dorsal preapical bristle.

Biology

File:Micropeza corrigiolata - 2013-06-03.webm File:Neria cibaria - 2013-07-28.webm Some species, much the same as in the strongylophthalmyiid genus, Strongylophthalmyia, mimic ants; others mimic wasps and are especially similar in appearance to some ichneumonid wasps. Species of the genus Anaeropsis have stalked eyes.

Little is known of the larval habits, but they are probably phytophagous or saprophagous in decayed vegetation, old manure, or fungi. Larvae of certain Mimegralla species have been found to live in the roots of ginger and other plants, under the bark of dead trees, or in other decaying material. Species of Micropeza have phytophagous larvae feeding in the root nodules of leguminous plants in open habitats. Species of Rainieria develop in rotting wood and are found in old forests. Adults are either predatory on small insects (for example Calobata in Britain[1]) or are attracted to excrement or decaying fruit. Adults are found on low herbage, flowers, leaves, rotting fruit, and excrement.

Many species (for example those of genus Mimegralla) are known for their habit of standing motionless while waving their prominently marked front legs in front of their heads, a behavior which contributes to their mimicry of wasps. At least one species of Metopochetus (M. curvus) was observed to wave its hind legs instead, though these are not conspicuously colored.[1]

Conservation

Calycopteryx mosleyi, found on the Kerguelen Islands and Heard Island, is associated with the Kerguélen cabbage (Pringlea antiscorbutica, Brassicaceae). As this plant is being destroyed by introduced rabbits, the fly is considered vulnerable.[1]

The larvae of Badisis ambulans live in the pitchers of the endangered Albany pitcher plant (Cephalotus follicularis, Cephalotaceae).[1]

Fossil record

Several fossil species have been found in Baltic amber, probably from the Late Eocene (about 36 million years old). However, most were washed onto beaches after wearing from Tertiary strata, making their age uncertain. Two fossil genera are presently recognized, Cypselosomatites Hennig, 1965 and the advanced Electrobata Hennig, 1965 which may be more than one genus however.
