A Sweetpotato Armyworm Moth--don't you love these names. This species is a Southerner with a range spanning from Texas to South Carolina. In the small photo (06/15/15, 10 pm), the wings are slightly spread but most of the time the moth has them closed and looks nearly elliptical as shown on the left.
