Pale Beauty (Campaea perlata) is a common species here; I've been seeing them sporadically for most of the season, but this weekend the temperatures were comparitively cool, and it seemed to be one of the commonest local species in Jaffrey. We even saw one at the summit of Mt. Monadnock. Having seen a few dozen, I'm fairly sure this was the largest one I came across and with the best color - they seem to vary quite a lot.
