This is a pretty picture. There are reflections and rotations in it. If you were to print this picture out and cut it all the way in half through any point, both sides would be exactly the same!

That looks like a Large Blue, or Phengarious Arion, which lives in Europe and some parts of Asia. They seem to be in a kaleidoscope-like viewing chamber.
