The Latin name of this striking butterfly is Delias rosenbergi.  It's native home is Sulawesi, one of the Indonesian Sunda Islands located between Borneo and the Maluku Islands.  The crisp colors of the lower wings gives it a bright color-block look, while the opposite side in black and white has a more classy feel.  The earrings wires can simply be opened and the earrings flipped to get the reversibility, and the pendant is made to be worn on either side.
