Tabanus autumnalis, the large marsh horsefly, is a medium-sized species of biting horse-fly. It is somewhat scarce compared to T. bromius and T. bovinus. This species shows slightly more of a preference for coastal marsh than some of the other European Tabanus, sometime even found in saltmashes. Wing length is 13–16 mm and about 16–22 mm in body length.{{cite book|author1=Stubbs, A. |author2=Drake, M. |name-list-style=amp |year=2001 |title=British Soldierflies and Their Allies: A Field Guide to the Larger British Brachycera|pages=512 pp|publisher=British Entomological & Natural History Society |isbn=1-899935-04-5}}{{cite journal |last1=Moucha |first1=J. |title=Horse-flies (Diptera: Tabanidae) of the World.
