Coordinator notes: If this is in the Spring Mountains it may be the "endangered" subspecies robusta, if more in the Mojave Desert, it would be subspecies neumoegeni, the latter known to have fall flights after wet summer rains. If robusta, it would be signiificant. The upperside here looks more like palla than neumoegeni which may mean it is robusta. Or it may be extreme variation. I have had no reports of a fall flight for robusta. I can't tell without knowing what normally flies at Corni Creek, a place I've never been.-Ken Davenport
