Had a swarm yesterday - saw them go by the barn. Lots of room in our hives, but decided to check anyway. Likely suspect was a hive with a poor laying queen - opened it up first & there are still lots of bees (aggressive now due no queen?) & lots of Queen cells - about 50/50 capped/uncapped. Anyhow, decided not to worry about the swarm as we didn't like that queen, which begs the question; will a queen about to be superseded swarm?
Golden rod & asters are in full swing right now + some clover, vetch, etc.
