I will describe what I am seeing of the weird hive, then I give you history and all important misc info:
The bees approx 150 are on the ground, directly below landing, 6 clusterers as if balling a queen, bees crawling, disorientation, trying to fly but most cannot. The bees slowly crawl off into the grass where I assume they die. Only 3 dead bees in front of the hive. Bees are different ages as determined by the hair or lack of on their back. Wings have intergerity, no dwarf wing virus, no K wing, no nosema. NO FIGHTING, none. A massive orenitation flight is what caught my eye to this hive, then I noticed clustered bees on the ground, like a tiny swarm.
All hives are on 18 inch stands. This is a double deep 10 frame Lang, very strong good population, 1 year old with adjacent healthy hives only inches away. In fact all 22 hives including nucs appear normal except for this one single hive. The stores are good, having several frames of capped honey and pollen. The bees on the entrance appear normal, maybe 150 to 200 bees and act very normal, just like the other 21 hives. Pearl white larva, capped brood as well, inspection showed nothing abnormal. Lots of healthy bees. Pull out bottom board is normal.
I am guessing here and way out on a limb. Did I see an attempted swarm takeover that failed. I checked the clustered bees, the ones on the ground to see if indeed there was a queen, just bees balled up is all I could see.
I will keep checking this hive and give updates as I see them.
4:20 pm, 3 hours later, maybe 30 bees clustered on the ground, unable to fly but the wings are ok. I did gather some bees from the ground, placed these bees in the entrance and the guard bees paid no attention.
Any ideas.
