The Glasswinged Butterfly

Greta oto (glasswinged butterfly) is a brush-footed butterfly. The transparency of its wings results from the combination of three properties: first, from the low absorption of the visible light by the material constituting its wings, second, from the low scattering of the light passing through the wings and finally, from the low reflection of the light impinging on the wings surface. Adult glasswings can be found mostly from Central to South America as far south as Chile. They can migrate great distances and have been documented as far north as Mexico and Texas.
