Coordinator notes: Alan: At least one of the photos is identifiable but without seeing the individual spread my ID is tentative. Size doesn't show in the photo. I have a good series of this butterfly, but seeing these on a hilltop seems odd but I know these occur in that area. Contrary to what some books say, Thorybes diversus and pylades can fly together-Ken Davenport
