This is just a try
But it has it´s larvatime to middle November (in Denmark) - maybe later more south?
And it vary quite a lot regarding to the back-pattern.
Watch especially photo no 7 and 8 on this site:
And photo 1 and 4 here:
But this is not a safe identification ... I don´t know the species myself
And agree: I don´t "like the small brownish analplate" .... hmmm
Otherwise, I can´t see, what else it could be - in november
Maybe others have a better idea
Kind regards - Kjeld
