Ant Species of Montana

This checklist is based on Wheeler and Wheeler (1988) and contains 76 species. The records used by Wheeler and Wheeler include: G.C. and J. Wheelers' personal collection, Borchert and Anderson (1973), Youngs and Campbell (1984), and specimen records from W.S. Creighton, D.R. Smith, Roy R. Snelling, and M. W. Wing. The status of each name given in the checklist was verified (Bolton 1995) and, where necessary, changed to reflect currently accepted names.

The ant fauna of Montana certainly includes a number of undescribed species. Some of our common North American genera, like Formica and Myrmica, are sorely in need of a taxonomic revision. Until these and other poorly described groups are revised and our western ant fauna is better characterized, this list will have to serve as our best estimate of the ant fauna found within Montana's borders.
