This is a silver-y moth, Autographa gamma. It is quite common across large parts of Europe (including the UK).
It is one of several species around the same size and stature that have a metallic spangle in the middle of their forewings; some are silver, others golden.
[aside: how come, in the English language, we have the adjective golden for gold-coloured but we don't have a corresponding adjective for silver-coloured? (I'm ignoring auric and argentic)]
It is sometimes seen flying in the daytime; I remember seeing them on Mum & Dad's honeysuckle in the UK in the evening.
BTW, thanks for a good photo - makes identification a lot easier!
