Just returned from a trip to the Osa Peninsula, Costa Rica. While walking on the beach I photographed this beautiful butterfly. Black and green swallowtail. Is it in the Graphium family or??? thanks,
It might seem deceptive that it is brightly colored, flies by day, but is not a butterfly. This is a Swallowtail Moth, Urania fulgens. We found a website that indicates that this Central and South American species occasionally ranges into Florida. This species is prone to population explosions and mass migrations.
