For in and out, above, about, below,
'Tis nothing but a Magic Shadow-show,
Play'd in a Box whose Candle is the Sun,
Round which we Phantom Figures come and go.
From Edward Fitzgerald's Rubaiyat of Omar Khayyam
Thank you for the comments. Yes, actually the butterfly had just landed and I was lucky enough to capture it before it took off again (which was seconds later). This is a very interesting one, I will post a picture of the outside of the wings..it is completely different...
