Assasin or Wheel Bug

I was showing one of the campers yesterday a cone flower that had two cones attached with pedals that were growing around the middle, when I came across this really cool Assasin Bug (or Wheel Bug). It was in the coneflower bed behind the carriage house, along the sidewalk. As you can tell it is using its rostrum to pierce then suck out the insides of the bee. This is a really cool web site to go to: http://www.ivyhall.district96.k12.il.us/4TH/KKHP/1INSECTS/assassin.html for the people who want to learn about the mechanics of it all. I just found it awe inspiring, we usually just see them hanging out on a leaf or the buildings.
