On hogweed on damp path at entrance to wood. Good puddles nearby.

Thanks Stephen, I think it is probably solstitialis as well, but I didn't catch one to confirm. However the thorax looks suitably dull, so that would be my guess. I think I have seen a female as well as this male today, and if so, it is a new species for me, so I am happy about that.
