I can see bee activity slowing down after the Thistles stopped blooming. It seems there is nothing mush left out there in this mono-crop agri-landscape.

Once you see bees working flowers which aren't good sources of nectar and pollen foraging has turned into scavenging. They trying to squeeze all whats left in this locality.
