Marlow(that's him in the suit!)is a local beekeeper with a few hives in North napa. He follows the city code for BMPs and keeps his neighbors happily in honey. if his colonies are primed this time of year, he has been able to share his genetics with other members of the Beekeepers of NV club.  understanding swarm management is so important, especially in the city limits. but if you don't get in there in time to catch it and split, hopefully they'll cluster in your own plum tree while you are out working in your garden to witness the show. Thanks to Marlow and his wife for their generosity and letting us beek out with them.
