Coordinator notes: Your suggested ID is correct...a male with characteristic well developed apical black markings...this is probably form calyce which flies in the summer (one flight) at high altitude...the same form flies in the spring at lower altitude (under 6000 feet). The veins on the underside of the hindwings are heavily colored with green scales. Mike
