Spring butterfly migration

British Columbian nature blog Huckleberry Days has a report with photographs about sighting California Tortoiseshell Butterflies (Nymphalis californica) on British Columbia's Sumas Mountain. (Which is not the same as Washington's Sumas Mountain.)
In these parts, California Tortoishells are migrants from the south. The species ranges as far as Arizona and Baja California.
