The butterfly needs sunlight to flutter around. Once the sun is gone, he will stop, since no battery function is included. But that does not matter, because he is by the color also as a cute looker in window boxes. When the sun is then there flapping and rotate like mad. The butterfly can also be operated with battery, if you "hold" him in the apartment would. It's a gimmick that's fun in looking. We therefore five stars.
