This is a Five-Spotted Hawk Moth, the Adult Form of the Dreaded Tomato Hornworm Caterpillar
Manduca quinquemaculata. I have never seen the moth at my home, where the tomato plants get destroyed. This was a couple of hours drive away, at dusk. I thought it was really pretty so I let it pollinate my friends’ flowers unmolested. Now that I know it’s identity, I want to go back in time and make it explode with a tennis racket.
