Greta oto may sound like the name of a silent movie star from Eastern Europe but is, in fact, the scientific name for one of the most exquisite - and little known - species of butterfly on the planet. This butterfly's claim to fame is that its wings, spanning up to six centimeters, are almost completely transparent. That's right, you can see just about right through them.
