Range Description

This is a widespread crayfish species found from Maine and Connecticut in the east to eastern Colorado and Wyoming in the west, and from Kentucky in the south to southern Manitoba, Ontario, and Quebec in the north. Its presence in New England, including New Hampshire, Rhode Island, Vermont and Massachusetts are probably the result of introductions. The presence of this species in Connecticut is questionable (Fetzner 2008, Pflieger 1996, Hobbs 1974, Hobbs 1989, Williams 1945, Aiken 1965, Simon et al. 2005). Since this species was introduced into Europe in the early 1990s is has steadily spread along the Rhine in Germany (Gelmar 2006). The native Extent of Occurrence (EOO) of this species has been estimated to exceed 6 million km2.
