Crab spider

It's not the flower or the fly but the spider eating the fly on the flower that's the subject of today's post.
At first glance I only noticed the fly and thought the centre of the flower looked a little misshapen. Closer inspection revealed the grizzly truth.
This is a crab spider, Misumena vatia. They are commonly found hunting in flowers and can change their body colour and markings to improve their camouflage.
