Peacock flies
Callopistromyia is a genus of small picture-winged flies (family Ulidiidae) known for the distinctive courtship displays of males, which hold their patterned wings perpendicular to the body while sidling along substrates. The genus contains two species: C. annulipes (the peacock fly) and C. strigula. Adults are typically 3.5–5.5 mm in length. C. annulipes has expanded from its native North American range to become an established alien species in Europe since 2007.
