Hello Jerry & All,
Jerry said:
2) Mite infested colonies sometimes march out en mass, clump on ground
(usually die shortly thereafter). I've seen this on several occasions.
I have seen the same thing also. In fact if on the ground I usually pick up
( to help land owner) but do not bring into my yards. If not AHB as Jerry
suggested in my opinion the swarm has a problem.
One such swarm (not from my bee yards ) was simply laying on the ground in
fresh cut grass. I could see varroa on the bees.
