I am always amazed the first time I see a Luna Moth, one of the largest moths of North America. With a wing span as long as 5 inches across, these members of the silk worm family are stunning. You can distinguish males from females by the thicker, feathery antenna males have. I usually only see them at night early spring and summer. Adult luna moths live about a week, long enough to mate.
In some areas, luna moths are endangered.
