Pretty Little Beetle

A flower - some member of the chrysanthemum family - with a sweet little beetle. The only thing I could find in my book that looks like this beetle is a Bean Leaf Beetle - Cerotoma trifurcate - but in some ways it doesn't look quite the same, and this is definitely not a member of the legume family that it is sitting on. In any case, I thought it looked quite pretty on this newly opening flower.
