These smart black beetles were making quite a mess of Alnus glutinosa, Alder. I have seen them on A. cordata, too.

Blue black not metallic green

I would expect Chrysomela aenea to appear as metallic green. The beetle in the image provided are blue black, have the bigger feet, and are found near the North West of England, which leads to me to believe that these are Agelastica alni.
