Please help me improve this site by sending sighting data (species; location [county]; date) to
Bill Oehlke.
Images are also greatly appreciated and will be used and credited (with permission) on county pictoral checklist. see bottom of this page. I will attempt to identify any Sphingidae larvae or adults that are unknown to you.

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.
