what is this move called?

This move is part of my Pole Art photography series and I've been calling each image "Pole Art - ..." and then whatever the move is called... only thing is I'm not sure what this is! Normal butterfly for me would have the back leg bent so perhaps this is Butterfly variation?? Not sure if it has a different name or not so at the moment I just used Split grip.... Would like a proper name though not just a grip title http://www.flickr.com/photos/licquidgoldphotography/5173497946/ Thanks peeps 🌸
