That's interesting - I've always known Idea leuconoe as a Wood Nymph. I rather like 'Chinese Kite Butterfly'. Not sure how appropriate the 'Chinese' bit is though - it's rather more widespread than that, I think.
I just did a quick bit of research and it is called variously, Rice Paper Butterfly, Tree Nymph, Wood Nymph or Paper Kite. Apparently the range of this species does not include China. I can't remember where I got the name from now. Thanks for putting me right Maguari.
