Wifey - that's funny. I was running around the room trying to shoot these big blue butterflies that never seemed to settle. From a quick look at google, it looks like I ACTUALLY DID get to shoot one. This guy :)
Further investigation - And a trip to another butterfly garden has shown this to actually be an "Owl Butterfly" - distinguishable from the Blue Morpho by having only ONE big eye versus many for the Blue Morpho.
