One of my favorite things is to watch the undertaker bees. I see one wrestling with a large thing on the concrete, and worry I have some robbing going on. Next I notice the large thing isn't moving, so sigh relief, and watch as the bee struggles across 3 or 4 feet, finally gets a grip, and flies of into the barnyard.
How they get that body, the same size and relative weight, up that high in the air, then fly off until they can't be seen fascinates me. They do the same with your newspaper and any other trash they don't want there.
