I found this moth on my living room window screen here in the Sierra Nevadas of Northeastern California. I looked through your photos of Sphinx moths and did not find one like him. Can you tell me what he is? I also had the pleasure of finding a Ceanothus Silk moth on the wall of my house the other day! I will attach a couple photos for you! Thank You,

We probably had still not posted the image we received from Canada on June 9 of a Wild Cherry Sphinx, Sphinx drupiferarum. That image showed the resting position and it is great that you have supplied us with an image of the underwings as well as a finger for scale.
