Glasswing, Greta oto

Between the veins of these wings are scales that appear to be translucent…but these scales are like mirrors. The colorful patterned scales on the wings of most butterflies are designed by Nature to ward off predators…but the glasswing protects itself by being nearly invisible. The only way that you can tell that it has wings at all are the dark edges. If not for these dark edges, the glasswing would be nearly invisible.
