Comments: This spicebush swallowtail butterfly was observed feeding on milkweed flowers. Note that spicebush swallowtail butterflies are quite similar to black swallowtail butterflies. Spicebush swallowtails have a marking that looks like a comet among the row of large orange spots on each of its rear wings (see photos). The black swallowtail just has another orange spot where the spicebush has the comet marking.
