In Southwest Ohio. I found a very active hive today with a pile of bees at the entrance. Not all dead - many were moving but not crawling- just wiggling a bit. A few crawling slowly. I estimate about a cup and a half worth of bees in this condition. Previous to this, they were about an order of magnitude more active than my surrounding hives, with unusual numbers of bees bringing in pollen. I wondered about robbing, but I don't know if bees bring in pollen when robbing. I suspect not. No deformed wing visible. Just this kind of incapacitation.
