Limenitis arthemis rubrofasciata (W. Barnes & McDunnough) ? author & date
Identification
Upperside usually with prominent orange spots near outer margin of hind wing. Underside usually orange-brown in color with orange submarginal band outside of white band little or not divided.
Hybridizes or perhaps intergrades with L. lorquini & L. weidemeyeri where they meet to the southwest in ne. Washington, w. Montana, n. Idaho, British Columbia, and sw. Alberta. Not all specimens in this region will fit neatly into one or another species, but will be intermediate in character. Blends with subspecies astyanax southward on Prairies (and, if eastern populations are the same, blends with subspecies arthemis southward in Great Lakes region and east through New England).
Range
In Canada from western Ontario to Alaska, south sporadically in northern U.S. into Minnesota, Dakotas, Montana, and perhaps Idaho and Washington. Eastern limits are uncertain, but perhaps ranging to Atlantic coast in Canada and Maine (see "Northeastern Segregate").
Food
Deciduous trees and shrubs. Apparently mostly Aspen (Populus tremuloides), but probably other genera as well (? Salix, ? Prunus, etc.).
Remarks
Overwinters as young larva in hibernacula (shelter made of rolled leaf). Adults mostly in June and July.
