A while ago I read this piece on Pollen Cell Encapsulation, where bees entomb poisoned pollen. http://www.naturalnews.com/032057_honey ... ollen.html Today I was looking through the frames of my dead hive and found this: It had been sealed in that odd gray-brown stuff, not propolis like the article describes. I broke it open - It is hard on the outside, but not really thick like a mud-wasp nest, so it broke easily. This frame has been sitting around, stored outside, for months. If it was there when I cleared out the dead hive, I did not notice it - but it was the end frame, against the box, and I did not pull every frame out at the time. Has anyone seen anything like this? Is it the doing of bees? Something else? Always in the back of my mind is the pesticide-happy farm next door.
