If you don't make it as far as the comments, ESP sent me this ID on the above moth. It's the Ailanthus Webworm Moth, Atteva punctella. Very interesting, as it's preferred host is the invasive Ailanthus (Tree of Heaven) tree. Unfortunately, it doesn't seem to kill them. I wonder if it hosts on other trees as well. That's my next little research job....
