The bees at Berwick are definitely hunkering down for autumn. The wax moth seem to be taking the hint from the bees and the takeover bid appears to have been deflected for the time being. The second hive is showing signs of defence, with the bees clustered at the entrance on guard duty.
You can see here how the bees are behaving defensively at the hive entrance, looking out for intruders rather than foraging:
I saw no trace of the wasp spider, but an orb web spider was taking advantage of her position next to the hive to snag a honey bee. Rather morbid but fascinating all the same.
