Thanks very much for this identification. I thought I could figure it out, it is a fairly unique looking moth and it's a good-sized moth, to boot. But I just couldn't find a match. And I was starting to think that no one at BG knew it, either. Turns out not many have ever seen one. Ann H would have known it instantly, because she is one of few that have ever photo'd the species, but she is away from BG these days. Thanks so much for figuring it out.
