Tangle-veined Flies feed on nectar and flowers, using their long proboscis – They are from the family Nemestrinidae and have relatives in the Tabanidae etcetera, such as March Flies and Horse Flies, that feed on blood. They can hover, and sometimes are mistaken for the BeeFlies of the family Bombylidae, but Nemestrinidae have shorter wings and their abdomens are longer and pointy. Their larvae are parasitic.
