Hybomitra epistates  Reference

Only a few individuals have been captured to date. The species is transcontinental and is apparently common. Larvae are found in wet moss in rather open woodland marshes and swamps (Teskey, 1990).

This species was the most common tabanid captured in Manitoba traps in Wisconsin by Gojmerac & Devenport (1971). Catches of H. epistates in canopy traps were increased 4.5 times with carbon dioxide (Leprince, 1989). Magnarelli & Anderson (1980) described feeding sites (mostly on the back and sides) and the frequencies of disrupted feeding (55%) on cattle in Connecticut. They identified 8 of 8 blood meals as having come from bovines, with the rest from deer and horse.
