Deuterophlebiidae, commonly known as the mountain midges, are a small family of nematocerous flies represented today by a single extant genus, Deuterophlebia. Adults have broad, fan-shaped wings, and males possess extraordinarily long antennae, which they use in territorial displays above swift mountain streams while awaiting emerging females.
