Greta Oto: the Glasswing Butterfly

submitted by oxdottir

I didn't find this video at Neatorama, but I found this text there:

Transparency in animals is something that is still not entirely understood by science. The beautiful Glasswing butterfly possesses this feature in abundance - a great percentage of its wingspan is almost completely transparent.

It is thought that the wings have large amounts submicroscopic protrusions that have the same refractive index which means that they do not scatter light, so giving the impression of transparency. Whatever the reason, this is a startling and little known creature.

There is a much longer video here: http://www.youtube.com/watch?v=EigXYgc8A1A (but I didn't think the extra four minutes were worth it--it's all about the butterfly)
