Unidentified butterfly

I am not sure if this is a Meadow Brown or something else.  It would not cooperate and spread its wings.  I spent the day in work today and was fairly busy with little jobs.  I am beginning to get sorted out for a return to France but there is quite a bit to do before then.  A handgrip incorporating extra dials and a battery holder arrived today from Olympus which was a special offer freebe for cameras bought before the end of August.  Doubling the battery life will be useful but it will add to the bulk of the camera so, as I don't take many portrait orientation shots,  it will be a case of suck it and see how I get on with it.
