Idea Leuconoe Butterfly

The Paper Kite, Rice Paper, or Large Tree Nymph butterfly from South East Asia.

One of many today at Edinburgh Butterfly and Insect World. Big-ish fella.
Off topic for the weekend challenge for 'curiosity' but as I was curious I googled this one and loads of references to it being 95-115cm wingspan. Mine was only ~10cm, so either I've got the wrong name or there are a lot of scary large butterflies out there!
