You are right about the late swarms in abundance. I have had more in the latter part of the year than in the first.
I just picked up (Sept. 2) an open air hive in a crape myrtle tree with 4 combs about 6-7″ wide and 4-5″ long. The man who called me said it had only there about 3 weeks. All in all there was about 3-5 pounds of bees.
This will be a year to remember for late swarms and they seem to be primary swarms at that.

Peaches

We’ve seen a higher number of large late summer swarms this year. And a large increase in small, likely after-swarms too. Not sure if it’s Africanization, high rainfall counts, moderate summer temps or what this year.

Bee well,
