Can someone tell me this guy’s name?
We found him lying in wait in a patch of Margariten. He ambushed a beetle, a Rothalsbock (Leptura rubra) while we were watching, but I wasn’t quick enough with the camera. The beetle got away.
Update: Best guess so far after googling is misumena vatia, (Order: Araneae, Family: Thomisidae) or a white crab spider (weiße Krabbenspinne). This one is missing the variable red markings on the side. They can also change color to yellow by producing pigments in the outer layer of cells. This change takes up to 25 days. They can also change color back to white in about six days. (source:http://en.wikipedia.org/wiki/Misumena_vatia)
