We found this large moth clinging to the radiator on our motorhome on our return home on May 23rd. The body was about 2 inches long and it would have been picked up locally near Houston, Texas, as we'd just had the vehicle in for a service. We were able to remove it and set it free on our deck, where it flew up and rested on the overhead beams allowing us to get a few photos. I only have butterfly books, so would appreciate an id if anyone can help me.
