There are several species of Blue butterflies that you might see on Mt. Hermon in the HolyLand (Israel). They are all tiny, and identifying them requires that you see both the upper (dorsal) wing and the lower (ventral) wing surfaces.
When I saw this one, there at the northeastern tip of Israel, this bluer than blue dorsal wing surface kind of shocked me. I was so fixated by this extra ordinary blue that I forget the make sure that I saw its ventral wing patterns.
Sitting here with our Israel Butterfly field guide, by Dubi Benjamin, I can’t be sure of its species. It’s blue as blue can be, and that’s just got to do. No?
