A Catalog of the Nearctic Diptera (Stone, 1965) gives the range of Tabanus sackeni as Kansas to New Hampshire, and south to Georgia.
This is one of the twenty-four fly species and one fly genus named for Karl Robert Osten-Sacken listed in the 1965 manual. Sacken was a Civil War era Russian diplomat in New York, and an avid student of insects, particularly of Crane Flies and Horse Flies. Osten-Sacken was the author of the Tabanid genera Atylotus and Diachlorus, as well as numerous Horse Fly and Deer Fly species.
