Swallowtail butterflies are large, colorful butterflies, and include over 550 species. Though mainly tropical, members inhabit every continent except Antarctica. The Cobalt Swallowtail somewhat resembles the deep blue Morphos of South America but is only distantly related. As its wide range suggests, there are many different subspecies, though all feature the iridescent deep blue and velvet black boarders and teardrop hind wing tails. It has an impressive wingspan up to 4½”.
