Common Name: Glasswinged Butterfly

Scientific Name: Greta Oto
Wingspan: 6.1 cm (2.2 to 2.4 in)

Location: Mexico, Panama, Colombia, Florida

The butterfly's most common English name is glasswinged butterfly, and its Spanish name is "espejitos", which means "little mirrors". The tissue between the veins of its wings looks like glass, as it lacks the colored scales found in other butterflies. The opaque borders of its wings are dark brown, sometimes tinted with red or orange, and its body is dark in color. 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.
