Ultra Green Sweat Bee on the apricot cosmos

For the first time ever, I spotted an Ultra Green Sweat Bee female Agapostemon texanus in the garden. From a distance she looked like a bright green jewel.

She spent a long time foraging for pollen on the apricot cosmos flowers.

Apparently this species is a fairly common visitor of gardens in the Bay Area.

Here is the sweat bee seen from above.
