Beautiful species with teal green and blue and red tones make up this exotic butterfly display. The largest butterfly here is called Blumei. It is also known as the "Peacock Butterfly". The stunning colors of this butterfly that go from teal green to teal blue tails is quite amazing. This butterfly is in my top 20 of the most beautiful butterflies in the world. That's saying a lot considering that there are over 20,000 species of butterflies in the world today.
