Small fast-moving hoverflies on the potentilla. I wasn't sure if they were mating or fighting but every so often a couple would collide and zoom away. They have swollen back femors which are black and orange with spikes along the bottom. I'm forever amazed at how much detail you see in the photos than in real life!
