This may be some of the coolest bees pics I've ever taken.
Pics
http://picasaweb.google.com/pyxicephalus/May292009#I really studied these bees today, hygenic behavior they got!
I know its a small picture but enlarge it if you can

I watched this bee come to the landing board with a small chunk of fresh white comb in her mouth. At first I thought it to be a fresh wax scale sloughed off but clearly it is too large for that.
My best guess is that it was a piece of fresh formed wax from the underside of the steel beam they had rested upon and this girl was toting it into the new hive location after having dislodged it, ain't she a smart one!
Hope y'all enjoy the pics, I sure am!
