Two Bumble Bees worked peacefully together pollinating a Cosmos flower that had recently opened its blossoms while a Hover fly on top of a petal inconspicuously waited its turn. I wasn't aware when I shot the picture early afternoon in our backyard, 10/20/2023 that I had also captured the fly, when my attention was focused on the bees. Hover flies are plant flies and they are beneficial also to nature.
