Terrible sight to behold.
Most people hate to see their hive swarm, and to witness it would be even worse if you could not see where they went.
I had a chance to see the remnance of a weak nuc abscond.
I HAD a nuc that has supercede queens 5 times this year. Each new queen would lay a partial frame of brood, then they would kill her or she would die. Then they would raise another.
At one time I checked the hive and there wre two queens in a 5 frame nuc. One was a nice long brown queen and the other was short fat and dark. She almost looked like a drone. Anyway, I let them decide who was best and it turned out to be the short and fat one. It took her over a month to start laying and by that time the hive was getting pretty weak. When she finally started laying, she did pretty good, she layed three frames right away and I thought it would be a good time to add 5 more frames on top when those hatched. So I checked the again, the hive was not crowder but it had a decent amount of bees, but the queen had stopped laying (again). I didn't know if she thought the hive was too crowded or what, but there were no swarm cells, not eggs and no brood, but the little short and fat queen was still in there walking around and eating.
So I added the top box a week ago...and today, I saw a lot of bees in the air near the nuc, I walked outside just in time to see them disappating, I opened the hive, and one of there frames had been robbed in a small spot, but other than that, all seemed fine, there were no SHB's present but the bees just left. When I opened the hive, there might have been twenty bees inside, but nobody seemed bent on robbing.
I had been nursing this nuc in preparation for the arrival of my 3 queens from BeeWeaver this week, but alas. NO good.
I have another week nuc that I added two frames of brood and bees just to keep them strong enough for the queen arrival. Maybe the queens will get here soon and I can get some bees built back up for winter.. Then will be back to 5 hives.
I will add a queen to a weak hive, a weak nuc, and split one of my strong ones.
This is getting old!
