Just witnessed another swarm here in Michigan, this late in the season. (I'll try to attach a picture) I don't know where all these bees are coming from but I'm pretty sure they are not mine. Too high for me to reach this time, but it's a good sized one. Every year for at least the past 10 years, I've seen swarms come in and go to this tree. I've witnessed a few of my own bees leave the hive and gather on this tree. I've even watched my bees leave a hive, swarm to this tree, return to the hive next to it and take it over. I've captured 2 swarms on this tree myself.
It's just a tall hickory tree. Any significance to this tree and swarms?
