Although lists of ants have been published for eight Midwestern states, Iowa (Buren 1944), Illinois (DuBois & LaBerge 1989), Indiana (Morris 1943, Munsee, et al. 1986), Kansas (Dubois 1985, Dubois & Danoff-Burg 1994), Michigan (Wheeler et al. 1994), North Dakota (Wheeler & Wheeler 1963, 1977), South Dakota (Wheeler & Wheeler 1987), Wisconsin (Burril & Smith 1919), the only published list for Minnesota ants is a list of 33 currently recognized species found in northeastern Minnesota (Gregg 1946). The list below was made by combining the list of ants of Cowling Arboretum and McKnight Prairie (present study, note that asterisks mark collections made during this study), the list of ants collected in Minnesota that are currently in the University of Minnesota insect collection, and Minnesota collections mentioned in the literature (e.g. Buren 1943, Smith 1979). The result is a list of 101 species.
