Margarethe and Rob, thank you both for taking time to reply.

leaf beetle, but see the discussion here

not Trirhabda
Margarethe, this is not Trirhabda but one of the smaller leafbeetles from the Galerucinae. A character to look for besides size are on the antenna. This beetle has the third segment of the antenna bigger than the fourth, while Trirhabda has the fourth bigger.
Since it was found near waterlelies it will probably result variation of Galerucella, but Pyrrhalta is an other option to look at.
Please look here, here and here
