About Tabanus autumnalis Linnaeus, 1761
Tabanus autumnalis, commonly known as the large marsh horsefly, is a medium-sized species of biting horse-fly. It is somewhat less abundant than T. bromius and T. bovinus. Compared to some other European Tabanus species, this one has a slightly stronger preference for coastal marsh habitats, and it can sometimes even be found in saltmarshes. This species has a wing length of 13–16 mm, and a total body length of around 16–22 mm.
