I inspected a colony today and noticed the bees in that hive were even more jittery than usual, they are like little jitterbugs, on the comb, and quite defensive. That could have been because of the cool weather. After tidying up I had a smear of bee poo on my gloves, it had a really strong pungent smell. I had never noticed before that bee poo had a particular odour, but this smell was bordering on offensive! The poo looked normal, yellowish, not brown and runny. Hope this is not a symptom of any bee diseases, nosema?
