When I came across the reference photo for this butterfly, I just had to paint it. I don't see that many butterfly around were I live. Quite a few years ago, I visited Cairns and they have a butterfly sanctuary at the top of Kuranda.(http://www.australianbutterflies.com/). They have some beautiful butterflies - I just didn't take that many photos back then which I now regret. I will have to see if there is any butterfly sanctuaries closer to home.
Eastern Tiger Swallowtail measures 3.5 x 2.5 inches and is painted on 300gsm smooth Arches watercolour paper.
Many thanks to Rodney Campbell for the reference photo.
