Coordinator notes: You have two different whites in each photograph. I deleted the upper photo which was as you suggested was a worn Checkered White (P. protodice). I kept and confirmed the second one which is the Western White (P. occidentalis). It has more extensive/complete black markings on the forewings in both sexes. In this case, the individual is a male.
