Hello! I am hoping you can help me identify this pretty moth. We are in the South Central mountains of Idaho, on a small prairie a mile high.
Your moth is a Columbia Silk Moth, Hyalophora columbia. BugGuide lists sightings in most parts of the U.S. excluding the south. It has several relatives in the same genus. The Ceanothus Silk Moth is found along the Pacific states, and the Cecropia moth if found throughout the east.
