Cobalt Swallowtail Butterfly on Graphite (11×14)
The Cobalt Swallowtail somewhat resembles the deep blue Morphos of South America, but is only distantly related.
It can be found in the Eastern-most Indonesian isles, Papua New Guinea, and Australia. As its wide range would suggest, there are many different subspecies, though all feature the iridescent deep blue and velvet black borders and teardrop hindwing tails. It has an impressive wingspan up to 4½”.
