Coordinator notes: This is a tough ID to make from a photo. Rocky Mountain is larger than persius or afranius, but you do not mention size. Lacking size info, the best diagnostic mark for Rocky Mountain is on the underside, which is a tough thing to photograph. Lacking that, the bold white spots on the forewing are pretty solid for Rocky Mountain. and the arrangement of the four smallest white spots near the forewing leading edge also support Rocky Mountain. Thanks for submitting!
