If you're in the right spot at the same time, you may get a double bonus: a non-native bee and a native bee on a native plant.

We took this photo in Healdsburg last week of a non-native bee (the common European or Western honey bee, Apis mellifera) and a native sweat bee (Halictus ligatus) sharing a plant native to the Americas: the sunflower. 

A golden moment.
