Thanks, rmptr, If I had a bunch of land ,I would keep them for the honey
Thanks, Backpacker, They were here for 2 and a half days that I know of
Hi Digs, Iv'e seen a lot of swarms over the years, next time I'll get more pictures and post them.
Thanks, kimsdad, It was a nice swarm, somewhere between the size of a soft ball and a football.
Hi , DD777, They balled up because they were on a rest stop [on my patio] from traveling. Also the temp was 62. degrees and droping for the night , so a tight ball helps them stay warm. They also balled to protect the Queen Bee in the center.
