I went out to take a look at my hives this afternoon. I have 6 langs (3 are nucs) and one KTB hive. There was normal traffic, but at the top bar hive I notices a large number of bees with what looked like a white stripe right behind the head on the thorax. It looked like white fuzz. This is the first time I have seen this. Does this indicate any type of disease or could it be pollen? The marking was identical on those who had it. I checked all the other hives and did not see this. I have not looked inside due to weather, but will tomorrow.

Thanks,
