Photographing butterflies

Not my most successful image and very over sharpened.

In fact I seem to have had one of those days today when none of the images I've taken has been good. I tried the long lens treatment and this was the only one that was anything like acceptable. I'm not sure what it is. I think it may be a Ringlet but I'm not too sure. They are fairly small and gather on the hedge and the marjoram flowers. I'm advised it's a Gatekeeper - many thanks for the identification.
