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.
