Adonis Blue or Chalkhill Blue?
NB: I have been looking through some images of Chalkhill Blues from Mill Hill taken this month and many have the full array of orange spots on the lower hindwing, and only a faint black spot in the large tadpole/anchor like mark. So I am happy to identify the butterfly on the immediate left as a female Chalkhill Blue. 

The photograph on the far left was taken on 7 September 2003.
