You can’t tell by the photo, but it’s raining, and these bees are soaked. I’m almost positive they came out of my fiber pot swarm trap in the background. But they may have come out of the spool colony. I’ll be able to tell upon closer inspection, since I marked hundreds of bees from the spool colony. If it had been a nice, sunny day, I would have shook some of these bees into a hive and watched the rest march in. But I decided today to just snip the branch, and lay them (twig and all) inside a nuc.
Two days ago, I collected a swarm a few miles from my house that issued from a nearby tree. I have a soft spot for tree bees, so I’ll be keeping them without requeening them.
Finally, I went to the house of a friend of mine to clean up a deadout and get it set up as a bait hive. Too late. A swarm had already moved in and they were dragging dead bees out, and bringing tons of pollen in.
