I had sun damage to the leaves in early spring and that looked different. Then I thought this was from hail maybe? It hasnt gotten much worse in the last four weeks, but maybe a little worse.
Bees are harvesting leaf material to make paper for nest this harvesting never damages a plant.
Leaf-cutter bees...as gator_rider suggested
Definitely leaf cutters
Thank you. I see on Wikipedia that they are good pollinators so maybe they are a good thing.
