Coordinator notes: Correct ID, an Olympia Marble. These are best distinguished from the similar Large Marble by habitat; Large Marbles inhabit canyons and pine forests in the foothills and mountains, while Olympia Marbles inhabit open prairie in eastern Colorado, up to the base of the foothills. Both use mustards, especially Arabis sp., as host plants.
