Papilo canadensis
Similar to Eastern Tiger, usually noticeably smaller, but identification can be difficult along the lengthy, narrow strip where their ranges meet, and some individuals appear intermediate. Underneath the forewing, the yellow marginal band in continuous, not broken as on Eastern Tiger. On the hindwing below, the black stripe nearest the body is wider. Black form females are rare. LARVAL FOODPLANT: Birch, aspen, black cherry and others. --- (Kaufman Field Guide to Butterflies of North America, by Jim P. Brock & Kenn Kaufman).
