Adonis?

This Blue that I filmed down EGP on Thursday, I thought was a Common, but isn't the white border diagnostic for Adonis? Commons have black borders, surely? Undersides are similar in these two species, even down to the spear shaped mark in the centre of the underwings. Any thoughts?

Quite right Andy. One description I was reading omitted to mention white border for Common Blue, and when printed on white paper, it becomes invisible in the illustration.

This web-site I just found gives better ID info -
