RHH's photos with the keyword: silvery blue

I think these are two different species of butterflies, A Silvery Blue on the left and a Spring Azure on the right. They were photographed in Derby Canyon near Peshastin, Washington, where 20-30 of them were drinking at a muddy spot in the road, a behavior known as puddling. I suppose it looked like I was puddling, too, since I was flat on my belly in the road taking pictures.

I believe this is the Silvery Blue, Glaucopsyche lygdamus, but am always willing to be corrected. There were a large number of these and of Acmon Blues at a muddy spot in the road when this photo was taken. The road was a Forest Service road in Derby Canyon near Peshastin, Washington.
