Observation notes: I think this must be a rather late date for the species. Flying with B. chariclea and B. eunomia.

Coordinator notes: Looks like a female. Might be late for location, although the Vail Pass area gets considerable snowpack even in lighter snowfall years. Latest record in mid-August...probably at a location like Loveland Pass above timberline. Mike
