I have seen this AVM thing too. sometimes ends up with the queen surrounded in a small cluster of bees in the grass or nearby branch. I have only seen this where queens have flown from apideas never from a full hive, presumably if it were from a full hive ie 5 frame nuc, then it would look like a normal swarm, the only swarms ive observed returning to a box is where the Q has been clipped.
So why is this mainly observed from apideas ? I still think that there is an element of absconding happening here, I've not observed masses of drones chasing a queen in the vicinity of the apairy site where AVM is taking place so this makes me wonder what is really happening
So, assuming you're right and Cooper was wrong on this it's looking like it may well be nothing more than the result of concentrating lots of colonies and/or virgins in a small area.
Then of course there's busybeephillip's hypothesis that there's an absconding component to AVM. Anyone have any further thoughts/observations on this?I am well aware that this statement may be disputed, for it has long been an accepted theory that virgin queens mate with drones high up in the air and at considerable distances from their hives. I do not now think this is really the case, at all events in breeding apiaries where there are large numbers of drones ready to give chase to every virgin when she flies. I think that in such situations the young queens are normally mated within quite a short distance of the hives and usually at no great height.

Smaller mating units are more likely to cause avm as the virgins are hassled out to mate sooner than they are old be from a more confident unit and so the virgin is less ready for lift off to break the immediate drone atmosphere of her apiary,,,maybe.
I have seen it from a full hive at Minnowburn where we have the association apiary.
I was working with the bees and I saw the mating swarm in the air. The queen landed on a post and the bees settled around her.
There were no apideas there at the time and when I checked there was a colony with an open supersedure cell.
I think this happens from full colonies but is far more obvious when you have 100 apideas sitting together when 20 or 30 queens might take a mating flight on the same day. Hard to miss under these circumstances. I have seen it at 4 different sites including my own garden so it is not some quirky coincidence with a congregation area.
The immature virgin theory ..... could be but virgins are very active and jumpy from a young age. If AVM was a very common event and related to Amm then queens with small clusters on bees landing wherever would also be a very common event resulting in the loss of a great many queens being unable, for whatever reason, to return to their colonies. In a large/medium mating apairy the result would be mayhem but this has never been shown to be a problem in large commercial operations otherwise we would have heard a lot more about it. Is there any evidence for these small clusters from (IMO absconding) apideas to decamp and return to the apidea ? or do scouts look for a new home.... This could explain losses of queens during mating. Logically, if queens are reared from material with AVM traits then this may result in an increased risk of queens being lost then this trait is not a good one for the survival of a colony and may also encourage inbreeding
So the colony had already swarmed with original queen or original queen was removed or died, first queen to hatch heads out with a cast, remaing cells hatch and head the colony ?
Maybe you distracted the swarm/mating swarm from returning to their hive? It does not make sense for them not to return to the hive if this is part of a mating event
I didn't know where the queen had come from and I collected her with the bees in a spare apidea. It was the next day I found the hive with the open supersedure cell.
I probably wrecked a perfectly good supersedure.
Funny enough, that colony went on for another year before superseding again. I found both queens laying together. The queen was in her 4th year at that point.
I mark and clip all my queens so if I find an unmarked queen in a colony it must have superseded or swarmed.
