Small Pearl Bordered Fritillary

I spent a very pleasant hour or so watching these little jewels at Llanymynech Rocks nature reserve yesterday, they were seldom still so I just sat down on a boulder and watched their antics as they fed and squabbled amongst themselves. This was the only one that I managed to get a picture of as it perched briefly on a plantain flower head in front of me, most were busy nectaring from Herb Robert flowers, a plant which seemed to be their preferred source of nectar.
