If you could identify this caterpillar found in southern Saskatchewan, Canada in the Fall that would be wonderful.
We believe this is an Achemon Sphinx Caterpillar, and it appears that it may have left its food plant and begun to hunt for a likely spot to dig into the earth and pupate. The Sphingidae of the Americas website indicates that there are no reported sightings of the Achemon Sphinx in Saskatchewan, though it is suspected to range in the region. Because of that, we are copying Bill Oehlke on this reply and he may request permission to use your photograph as well as to include your sighting data so he can update the status of the Achemon Sphinx in Saskatchewan. You can read about the Achemon Sphinx on the Sphingidae of the Americas website.
Yes, that one is Eumorpha achemon. Thanks for referral.
