Two weeks have passed since I declared that there was 'no drama'. Today Colony 11 is under severe pressure from wasp attack. Today there were maybe 3 or 4 wasps using the entrance for every bee. Inside there were far fewer bees than I would have expected and there was less honey. On the floor of the hive were a great many severed bee legs.
I removed the top 2 supers which were superfluous. I put a piece of thick paper over the hive entrance which seemed to stop the approach of the wasps -- at least for the moment. I am considering moving the hive as soon as possible.
