New species - Flower Crab Spider (Misumena vatia)

I spotted a tiny but striking spider atop a Spear Thistle flower and went back for my camera but it had gone when I returned so no photo. However the striking pale lemon yellow body together with milky white legs and it sitting on a flower give me confidence it is a Crab Spider known as the Flower Spider or Goldenrod Crab Spider. I do have trouble identifying spiders so it is good to get one that is readily identifiable.
