We photographed this moth today on the back porch of our house on Edwards Air Force Base California. We’re in the western Mojave desert. I’ve been unable to find a resource to identify it and was hoping you could help. Wingtip to wingtip was about 7 inches.

Hi William and Sara,
This is the second image we received today of a Big Poplar Sphinx, Pachysphinx occidentalis, also known as the Western Poplar Sphinx, from California.
