Black Witch Moth

Spotted resting on a screen door. I have had moths of probably this same species alight in the same place, but all prior attempts to image them have failed. The moths depart if they sense the slightest movement. On this occasion, the sliding glass door was shut and perhaps that is why I was able to get close enough undetected to capture a single backlit ventral image. By itself that picture is inadequate for making an ID, but because I have found similarly appearing moth wings (sans moth) previously, and because I received specific help from a PN Ranger, ForestDragon, I was able to make what I believe is the correct ID
