Coordinator notes: The simple spot pattern on uniformly gray-white ground color on the underside of both wing surfaces is diagnostic for the Silvery Blue. The Mountain Blue (P. glandon / rusticus) has a more complex pattern and colors. You can see that species on the BAMONA site or the "Butterflies of America" website. Mike
