Yesterday by the kindness of the master stinging insect remover here in Santa Cruz, I got a new swarm. They had nested in 1 metal barrel of an abandoned collection behind a county park's site's tool shed.
These bees are just huge and very, very yellow/gold! I've brought them home and placed them next to a hive that originated as a swarm that moved into my empty boxes two winters ago. That colony is gray/dark tan bodied and noticably smaller, though not regressed at this point (I'm in the process of that with Michael and Dee Lusby's expert guidance). I could really see the difference though it was very significant. These golden ones look like another insect almost - its weird and they are big!
Also they were very agitated when they got to my yard (we hived them the late afternoon before, left them at that site overnight, then closed them up 6 AM and brought them to my place). The whole day yesterday they were wild all over my yard. They were definitely hungry, but I'd never experienced that kind of mayhem. But then again I haven't had the experienc of more than 15 swarms or so.
