Anthomyzidae
Anthomyzid Flies
Anthomyzidae are small, slender acalyptrate flies ranging from yellow to black in coloration. The family comprises fewer than 100 described species distributed across approximately 13 genera, with highest diversity in the Holarctic region. Members are characterized by narrow, elongated wings that may display distinct markings or, in some species, exhibit wing polymorphism with greatly reduced wings. The family has been recorded from all major biogeographic regions including the Nearctic, Palaearctic, Oriental, Afrotropical, Australian, and Oceanian regions, with recent discoveries extending its known range to New Zealand and China.
Pallopteridae
flutter-wing flies, trembling-wing flies, waving-wing flies
Pallopteridae is a small family of acalyptrate flies comprising approximately 70 species across 15 genera, distributed primarily in temperate regions of both Northern and Southern Hemispheres. Adults are recognized by their characteristic wing vibration behavior, which produces the common names flutter-wing, trembling-wing, or waving-wing flies. The family exhibits diverse larval feeding strategies including saprophagy, phytophagy, and occasional zoophagy, with larvae developing in flowerheads, stems, and other plant tissues.
