A summer afternoon in a Berkeley Hills garden with my friends, the bees. Does anyone know the type of flowers these are? Impatiens? Jewelweed?

UC Study Counts Albany, Berkeley Bee Population.

The Berkeley Planet article goes on to write:

“If you’ve noticed a non-honeybee in your garden, odds are it was a bumblebee—maybe the yellow-faced bumblebee, which has the resounding Latin name of Bombus vosnesenskii. Their colonies are annual, like those of wasps; the workers die off in fall, leaving the queen to hibernate through the winter and found a new realm when spring comes.”
