I have 2 very similar ones from this Autumn. Lovely mottled caterpillars but I couldnt find a satisfactory ID and right at this stage I cant even remember the possibilities I found.
Just looking at it Angle Shades is a possibility, a young one of the brown type?
I really cant say. You probably have noted I have put a green one up based on the one in UKMoths. Please have a look at my comment on this topic here, love to hear what you have to say on this.

The 'here' link isn't working for me right now. I did see the green Angle Shades and I think it is more than likely correct due to the diagonal markings and overall appearance?
I saw a few possibilities for the brown one this evening but its not a straightforward one and I fear there might be more than one potential candidate!
