Mine usually swarm regular as clockwork last week May or first week June. However yesterday the strong hive that arrived as a swarm last year, were up in the air. I watched as usual expecting them to land somewhere but they didn’t. Five minutes later all back in the hive. (No, it’s not a mating flight) Two hours later, did the same again. I knew what to expect today and yes, just now for the third time, same again. I assume HM is unwilling or unable to fly with them. I’m not one for cutting Queens and not experienced this before so it’s a case of deckchair and popcorn and watch the show.
