Beautiful and Delicious | Though not as well-known as the orange and black monarch, the Eastern tiger swallowtail is a spectacular butterfly. Here, feeding on lilac blossoms, these pollinators, with sharply contrasting yellow-black pattination accented by blue and orange spots, are often more colorful than the flowers they service. Unlike the monarch, which has developed an effective predator defense, by feeding on milkweed and thereby rendering itself poisinous, the tiger swallowtail (Papilio glaucus) is a favored food of many birds species.
