One of my favourites at the Haga Ocean butterfly house is the gold rim swallowtail (Battus polydamas), also known as the tailless swallowtail and Polydamas swallowtail.
These seemto have a predilection for sitting on the floor where people walk (while looking up at butterflies) and this one was no exception. I put my finger in front of it and it climbed on so I could move it to a twig - which eneded up becoming a nice photo.
