Coordinator notes: Large Marble...best clue is the underside which has distinctive green "marbling" associated with the veins on the underside of the hindwings. Western White has about the same markings on the upperside but is a larger butterfly with broader developed forewings. You should also find it in the area from where you are reporting. Mike
