This yellow tiger swallowtail was sampling blossom after blossom on the "Carol Sing" daylily clump that is blooming near one of the hummingbird feeders. The late afternoon sunlight illuminated the butterfly's wings as it fluttered from one flower to another. Of course, I had to get my camera. I noticed that this butterfly was not one of the fresh, perfect, newly hatched ones. This butterfly is mature. The color of the wings has faded. And the wings are thinner, more translucent. I suspect the days of this butterfly are numbered. But it hasn't quit. Neither shall I.
