Brimstone

At least, if I was in the UK, a Brimstone is what it would be. As ever in Europe one is offered a choice with the alternative being a Cleopatra. I think however the tail here is too prominent and so a Brimstone is what it is - probably.  The orange colour visible through the upper wing is a bit of a worry........ So much so that I have probably changed my mind as to which speices it is. Any help appreciated.
