I found this Manduca rustica
(Hodges #7778) around midnight in a parking lot, resting on the pavement under a street light. After bringing it home and mounting it, I noticed that Bug Guide didn't have a Rustic Sphinx Moth from Missouri, so I took a photo and here it is; proof that Missouri does indeed have Rustic Sphinx moths.
My question is: Is it a male or female, and how do you tell?
