Coordinator notes: Glad you found one still flying. I don't think anyone found them during the Yosemite butterfly count. Actually Robert, I have a full series of the California Rockslide Checkerspot and the Colorado ones (not a full series) Chlosyne damoetas. There are actually two species going under the name Rockslide Checkerspot. It is better to look for them a little earlier in the season, they even stray down into Hudsonian Forest at the bottom of the talus slides, even down to Ellery Lake-Ken Davenport
