THis is a bit sneaky as it doesn't actually feature a butterfly but the stamp I've used is from the Butterfly Basics stampset so I didn't really cheat.
To create the background I used one of Stampin Ups fab clear acrylic stamping blocks and coloured it in using the maker pens. I then spritzed it with water and stamped it directly onto the whisper white cardstock, held it there to set and then, voila, a unique background! I stamped over this using the flower stamp. stamped in Staz On Ink.
