I'm not sure how I saw it, it all happened so quickly, but out of the corner of my eye I watched a small green-winged creature ricochet off the tractor-trailer driving in front of me. When it hit the shoulder of the roadway, I knew immediately what it was. A Luna Moth, Actias luna, one of the largest moths in North America and one of my absolute favorites. This sight alone rekindled the excitement of the summer nights of my youth when these giant silkmoths would congregate around a humming barn light. There they would be, sometimes two or three of them, clinging to the peeling paint on the wall-always far above my reach. A few times we'd gotten the ladder out and captured one of the beautiful nocturnal pixies for a closer look. There were even years when I was lucky enough to raise caterpillars that hatched from eggs laid by one of the moths.
