Our daughter was painting some picture frames in the garage last week after dusk with the door open and the light on. Who should be attracted, but a Luna moth, one of the largest moths with a wing span of about 4 inches. They are considered common but are rarely seen because they only live a week as adults (long enough to mate). The children were fascinated by this beautiful lime-green creature. We couldn't coax him out of the garage that evening, but he made his exit the next morning. Hope he found a sweetie to create a new generation of little lunas.
