Coordinator notes: This is what I call in our area as the "Mountain Blue" (aka Arctic Blue group) and not Boisduval's Blue (aka Lupine Blue). I think I identified one of your submits of this species earlier and noted characters that distinguish it from P. icaroides. Also note the blue color on the upperside of the male on the flower which is very gray-blue with a silvery sheen. The color is different than on any of our other Colorado blues. Mike
