Mt. Hood Square-spotted Blue - Euphilotes glaucon

Euphilotes
Agreed. It's very difficult to differentiate between Euphilotes from mountain top to mountain top.

It's most probably a square-spotted, and I'm not sure if the Glaucon species are being reserved for the highest Cascade mountain tops.

see also Blue Butterflies

This matches what is being called
the "Cascade segregate of E. glaucon.

E. glaucon is now being called a species separate from E. battoides, an arrangement that I suspect will be debated for a while to come.
