After I complained about bees doing a quick turn-around just as I tried to shoot a portrait, Debbe in Delaware sent me her best bee butt photo which is nothing short of fantastic. It is certainly one of the best photos I have ever seen of wax glands in action. She writes:
I took this photo a couple of years ago with an inexpensive point and shoot camera. The bee was from a recently installed package and was clearly confused about the inside/outside part of the whole deal [the bee was on the outside of the hive]. Nevertheless, I thought it was a cool picture; so for anyone who ever wondered about exactly where the wax glands are, this “butt picture” appears to provide the answer.
