Yellow Swallowtail

The eastern tiger swallowtail is one of the eastern United States' most familiar butterflies, and large and beautiful it is indeed. Tuesday afternoon, one (a female, I believe, based on the blue areas that can be seen on the hindwing) flitted from coneflower to coneflower outside our living room window. I don't know much about butterflies, but in reading enough to write about them here, I learned that although the male tiger swallowtail is always yellow, the females can be either yellow (with the distinguishing blue decoration) or virtually black.
