Papilio blumei (Peacock or Green Swallowtail) / Indonesia
 
The green swallowtail is a butterfly of the family Papilionidae.
It is found only on the Indonesian island of Sulawesi.
 
The remarkable feature of this butterfly's wing is that it contains rows of very small concave surfaces that reflect light in many ways. For instance, the centre of the concave surface reflects a yellow-green light and the edges reflect a blue light.
