Hyles euphorbiae
dark brown and tan moth about 1½ inches long
small town on the northern Great Plains
spotted on a sidewalk in Medora ND; thanks to Project Noah member J for the species ID
Thanks Allen! Appearance is actually a sufficient basis for many species.
Thanks for the ID suggestion, J. I know that appearance alone is insufficient basis for determining species ID, but given the similarities between the appearance of my spotting and of images available online, and given your apparent expertise, I'm going with Hyles euphorbiae.
