I had a look through my Fraser's Hill photos again and realized that I have overlooked one of the more interesting swallowtails.

This swallowtail was puddling in the same area where I had photographed Red Helens earlier in the day near Jeriau Falls. The white was more extensive and it had blue markings on the outer hind wings. I mistakenly thought that it was another Red Helen and only took a couple of quick shots. I believe that this was a Great Helen (Papilio iswara), correct?
