And maybe I should have phrased it differently - not ticked because I had destroyed their home, but ticked because they were out in the bad weather. A subtle but important difference. They weren't pissy when they were still in the tree and I was sawing and chipping away at their entrance, even though that was close to the same time. So, swarms in general, when approached during bad weather, can be aggressive, correct?
Any hive in bad weather usually will be very defencive. I suspect the worst part is when the storm is approaching. Not sure but it might bee that they feel the pressure change on their exoskeleton.
I taught a class,a hive inspection, on a cloudy day. Used my good bee suit expecting them to bee very pissy. Even after removing/inspecting 2 supers and a brood box, they were as calm as can be and I was able to remove the suit. Did not receive a single sting.
