I removed the feeders from both hives today and wrapped the hives in bee cozies. When I opened up the Benedictium, I was met with an angry force of guards, one of which stung me. I was only opening up the empty super on top, and the temperature was quite cool, around 40 degrees, but the Benedictium is a crowded hive with lots of extra bees. This was my first sting by a benedictiana.
At any rate, the hives are now winterized.
