Green dock leaf beetle

Hi again Micolo, I have had a look in my insect guide and these look very much like a leaf beetle to me, specifically gastrophysa viridula which it says is golden green and found on docks or related plants. it also says its found near water. I'm far from an expert on these things which is why i havent provided a formal suggestion but it might help you look in the right direction on the web. I think its the same as your other green beetle too.
