I don't like to arrange my nature shots and I try at any length to wait for nature to take its course and to be there when something special happens. I will admit that at times I do intervene just a little bit by, like in this case, lightly touching on the spider (after it had gotten a tight grip on it's prey) to make it move to the top of the flower instead of as it was when I found it, under the flower and hidden. I still needed to move around it since it kept moving around slightly with it's prey.

The Crab spider can hunt quite large insects, for ex. butterflies, as can be seen on this photo. I was lucky to see this at all as all I thought I saw was a butterfly standing on this Devils-bit Scabious flower. It moved a bit like any butterfly would and I got interested and wasn't that interested in taking a photo of this butterfly at first but decided to give it a try. Not until I looked at the shot through my macro did I realized that it had just been caught by a spider barely visible under the flower.

These Crab spiders can grow up to 10mm body length (female), males can grow at most to 5mm long. It's the female that's always seen in flowers hunting. These females change color according to the flower they hunt from but a change in color takes several days. The color change is induced by visual feedback.
