    Jonty,

     

    The first two are common blue, Polyommatus icarus.

    And you are correct about the second two: brown argus, Aricia agestis.

     

    There is very good guidance on separating these two (and other) species on Peter Eeles' et al's excellent resource on British butterflies

      Jonty,

       

      Just be grateful - the blues are.easier in the UK than on the continent!

       

      Considering all UK butterflies, not just blues...

      There are usually little features that can be used as differentiators; the UK Butterflies web site'll help in that respect. In fact, they have a special page for just that - http://www.ukbutterflies.co.uk/species_similarities.php. There are a few pairs they are still working on, but nonetheless I have to say 'great stuff'.

      The key features can be on the uppersides, undersides or elsewhere (tips of the antennae re Essex and small skippers). So I suggest you take photos from as many angles as possible. Even if some of them are poor photographically, they can make all the difference when it comes to naming.

       

      Mike
