White-headed Grape Leafroller - Desmia maculalis. - Desmia maculalis - Male
Elkridge, Howard County, Maryland, USA
August 12, 2017
I believe this is a White-headed Grape Leafroller - Desmia maculalis. It is a male as it has a distinct joint midway on each antenna, hindwing spot is not "pinched", and the wingspan is about 22 or 23 mm wide. The white "patch" on the abdomen is clearly broken with about half of segments 3 and 4 dark.

Size
Please fill in the "size" field, whenever you know the exact size of your bugs, thanks!
The second image can be re-cropped, since we don't need to see that much of the ruler.
Thanks for getting a ventral shot. I think that your ID is correct, but I'm double-checking this now. -- The fringe is missing. So, we can't verify that feature. Everything else looks good.
