I don’t know my flowers very well, but I think that this Eastern Tiger Swallowtail (Papilio glaucus) is feeding on some kind of tiger lily (Lilium columbianum). Tiger on tiger—I like the way that sounds. Whatever the case, I love the gorgeous colors of the flowers, providing a gorgeous contrast to those of the butterfly.
