I've only had the opportunity to snap a shot of them once. And that was the first and last time I've seen one in person but I picked it up and held it after so it was pretty neat! They are awesome indeed.
I'm sure you'll get more chances! A bunch of my pictures are from the Smithsonian's butterfly pavilion. It rocked because even if one flew away, there'd be another right next to it. And they loved my hair for some reason.
