Snow scorpionfly

Boreidae, commonly called snow scorpionflies, or in the British Isles, snow fleas (no relation to the snow flea Hypogastrura nivicola) are a very small family of scorpionflies, containing only around 30 species, all of which are boreal or high-altitude species in the Northern Hemisphere. Recent research indicates the boreids are more closely related to fleas than to other scorpionflies, which renders the order Mecoptera paraphyletic if the order Siphonaptera is excluded from it.
