Horse-fly is the most widely-used English common name for members of the family Tabanidae. Apart from the common name "horse-flies", broad categories of biting, bloodsucking Tabanidae are variously known as breeze flies,[2] clegs or clags, deer flies, gadflies, or zimbs. In some areas of Canada, they also are known as Bull Dog Flies. In Australia some species are known as "March flies", a name that in other English-speaking countries refers to a very different Dipteran family, the non-bloodsucking Bibionidae.
