There were many of these guys on the north end of Crex Meadows when the pictures were taken. The winds had come up so it was very hard to get a focused picture. The group would begin to open their wings for a pose and this would spread from flower to flower until most of the Coppers would be open. As soon as one or two took flight, the open wing display would cease.
It is very likely the Bronze Copper and the American Copper are also residents of Crex Meadows.
