YESTERDAY A NEW member of the Church O’ The Pines congregation showed up. A social butterfly, you might say, it would barely land long enough for the Parson to get a good look or snap a picture. Finally it paused for a few seconds on one of Kathy’s Impatience blossoms. This splendid creature, almost 5 inches across, is a Spicebush Swallowtail. Like so many of its kind, it is very quiet but makes quite an impression. A good way to be.
