Just returned from a tip to Kentucky. Saw a few there. Cookie took a couple pics, but nothing of publication quality.
As to look a likes, yes they exist. Mimicry efforts to avoid being eaten but I can't remember their names for sure. Possibly a Viceroy? Must be some real nasties in those Monarchs. A friend who still has his childhood collections reports that over 50 years or so vermin have worked their way in and pretty much destroyed every insect. The Monarchs though, look as good as the day he mounted them.
