Updated as per personal communication with Beth McCoy (Eumorpha achemon, Billings, Yellowstone Co., August 14, 2011); August 15, 2011.
The documentation of Eumorpha achemon in south central Montana indicates a significant westward entension of the range of E. achemon compared to the map range in James P. Tuttle's The Hawk Moths of North America, an excellent resource.
