I am not sure which of the large fritillaries this is. You need to get a good view of the underside of the wings to be sure and it was extremely uncooperative about this important issue, but it is either a dark green fritillary, or a high brown fritillary, or a niobe fritillary (only to be found in damp meadows in mainland europe!). It was fast moving and quite light coloured so it is probably a tattered high brown, and the forewing is gently concave. (there are lots of good butterfly
links)
