Coordinator notes: Your suggested ID is correct...although typically, the true Chryxus Arctic flies in even numbered years at lower altitude and a in the high altitude, another arctic occurs in both even and odd-numbered years, presently treated as a subspecies of chryxus (altacordillera) which seems to be a sibling species in several respects but is thus far shown not to be substantially differentiated genetically. If interested, you can read about this online in a publication...websearch (Google or Bing): Papilio (New Series) and find #12 or go to www.mountainscholar.org and search the same or James Scott.
