Wingspan 57-70 mm
Bold wing pattern is distinctive on this butterfly of western North America. California Sister is very similar from above (at least the California ones are), but doesn't have the extra row of white dots on the front wing-tips that this species has, and does have areas of blue on the underside that this species doesn't:

Also, the California Sister is found mostly around oak woodlands, especially near its favored host plant, Gold-cup Oak (Quercus chrysolepis)
British Columbia south to Baja California, also inland to Idaho, Nevada
River bottomlands, lakeshores, forest edges
April-September (two flights) in California. June-September (one flight) in Pacific Northwest
Adults take nectar
