Transparent Butterfly

Glasswing butterflies are known for their predominantly transparent wings (with the exception of the borders), and this is the reason they were named like this. The opaque borders of its wings have a dark brown color and in some cases are tinted with red or orange. Greta Oto has a widespan of about 5.6 to 6.1 cm (2.2 to 2.4 inches) while the body is mainly dark colored. The glassy wings work as a means of camouflage, helping the butterfly to better blend in the enviroment and as a result avoid more effectively any potential predators.
