Blue Morpho butterfly

We went to Wisley Gardens this afternoon as they've got butterflies in part of the glasshouse for the next month. According the spotter guide they have about 30 different kinds of butterfly. We probably only saw about 10 of them though.
I got a few good shots and had thought I'd go for one of the colourful ones like the open winged version of this one but this was the photo I got drawn to when I looked at them on the computer.
