A couple butterflies I hope you can help with. Both taken same location. Larimer county, Colorado foothills, 8100 feet elevation. October 8, 2014. Warm day, but well past 1st frost. … The second, I believe, is Gorgone checkerspot. Chlosyne gorgone, but not 100% certain. Sorry no pic of underside of this guy.

Hi again Matt,
We are not fully convinced that this is a Gorgone Checkerspot, as your individual appears to have different markings than the individuals pictured on BugGuide. We believe this might be a Field Crescent, Phyciodes pulchella, which is also pictured on BugGuide, or perhaps a Painted Crescent, Phyciodes picta, which is also pictured on BugGuide. Perhaps someone with better identification skills can assist us with this identification. We believe the fly in the image might be a Tachinid Fly.
Thanks again. You may well be right. Both look good, but I especially like field crescent. My ID was largely based on http://www.birrellfineart.com/Big%20Picture%20Pages/c57%20gorgone%20checkerspot%200017%20big.htm, which, of course, could also be wrongly ID’d
