This butterfly hassled me for 10 minutes while I picked red huckleberries at the base of Marys Peak.
Outside of wings had white markings on lower wings, but not on upper wings
Rhizomatous (I think) from how they grew in scattered clumps; lobed calyx; hairs not stiff; growing west of cascades in the northern half of Oregon coast range.
Mary's Peak road, above Conner's Camp, below upper waterfall. @markegger ?
