Pallopteridae is a family of flies. The various species are collectively called flutter-wing flies, trembling-wing, or waving-wing flies, because of the striking vibration of the wings in many species. Over 50 species in 15 genera are found in the temperate regions of the Northern and Southern Hemispheres.

Biology

Adults have been found on flowers and low-hanging branches in shady habits. Known larvae are phytophagous or carnivorous (some species preying on beetles of the families Cerambycidae and Scolytidae. One species is recorded as preying on larvae of from the family Cecidomyiidae. Some have been found in flower buds and stems.

Description

For terms see Morphology of Diptera

They are medium-sized or relatively small flies, they have spots on their wings (dark smoky apical spot in Palloptera ustulata). The wings are considerably longer than the abdomen. The head is semispherical and the postvertical bristles on the head are parallel or divergent. Vibrissae on the head are absent. The arista is bare or has a short pubescence. The mesonotom has four to six pairs of dorso-central bristles. Tibiae without subapical bristles. The costa is interrupted near the end of the subcosta. The subcosta reaches the costa. The subcosta is complete and well separated from vein 1. The cross vein closing the anal cell is usually convex and the angle the cross vein closing anal cell meets vein 6 at more than 90°. See [1]
