It's been a while since we visited the Berkeley Botanical Garden in Tilden Park, so it was
exciting to see some pollinators that don't visit our garden, as well as familiar ones.
It's usually impossible for me to capture an image of the small carpenter bees in our garden. They are tiny, resembling ants, and move very quickly. In the image above a small carpenter bee ceratina latreiile is on a California buckwheat eriogonum fasciculatum flowerhead.
And here is a field crescent butterfly, phyciodes . I've never seen one of these before.
