@Cherrill Thank you Cherill, yes I had seen and I meant to get back to you, the butterfly you suggested does look similar, but I have got other shots which show the underwing and its not the same species. I have been very busy but I had a quick look myself, but with 550 species of Swallowtail to pick from I think the easiest way is to nip to the Butterfly house over the weekend and pick up the ID guide of all their butterflies. I might a chance to grab a few more shots too.
