What a beautiful blossom!
I like the golden yellow of the Californian golden poppy much better than the cold yellow of the yellow poppy. For more than two weeks I hoped to catch a bee here in bloom, but unfortunately I was not able to do so. But it was nice to see the macro photos, how the lush pollen lay on the petals.
On one of the last days, a hoverfly sat decoratively in the flower and slurped the nectar — do you see it?
