Gathering Pollen

I was screening some soil for planting things on the west stone wall, and I had been instructed to remove the giant thorny, scary thistle plants from the area. I approached one and saw that on the bright pink blossoms there were two bees working themselves right down into the flower. By the time I went back to the house and got my camera there was only one, but I was able to get close enough before I "spooked" it to capture even the detail of pollen all over the blossom and the body of the bee. Maybe it would be a good photo for a segue way into a science lesson, eh?
