Somewhere in the past, the Eastern Tiger Swallowtail (Papilio glaucus) and the Canadian Tiger Swallowtail (Papilio canadensis) hybridized to form the Canadian x Eastern Tiger Swallowtail (Papilio canadensis x glaucus) that is common to the areas of Southern Ontario, New York State, Vermont and Massachusetts.
This swallowtail can be seen flitting above trees, shrubs and meadows searching for nectar sources that include lilac, thistle, aster, coneflower, milkweed and other late summer / early fall flowers.
