Butterfly or Moth - Question Mark

OK, which is it? Butterfly or moth? That was the question for quite a while, but on September 7, Hap from New Hope has identified it as a Question Mark butterfly. Thank you Hap. I am reposting this one now that I know what it is. Isn't it neat that it ends out to be named Question Mark after it was in question for so long. I am also posting right in the middle of my Cades Cove series, but this was taken on the my neighbor's porch rail, not is Cades Cove.
