Photo: Diane Edwardson, September 2, 2015. According to UC Berkeley's Urban Bee Lab, there are around 1600 native bee species in California. I'm not even going to attempt to ID the 1/4" long bee I watched drink from the chive flowers. (Click on photos to enlarge.)
Photo: Diane Edwardson, September 2, 2015. We always see a variety of bees and blue butterflies on and in the chives. The UC Berkeley Urban Bee Lab has a section on seasonal gardening for bees, along with links to regionally appropriate advice.
We've documented green, blue-green, and rust, gold & black bees. Click here for all our bee posts.
