James tells us he spent a lovely morning at Tout Quarry on 17/07/18 where he photographed these Chalkhill Blues.

The top photo is of a female and the above photo shows the markings of the undersides clearly for ID purposes. Common Blues have very similar underside markings, but the diagnostic markings are those around the rim of the wings, There is a chequered effect on Chalkhill Blues and a plain white rim on Common Blues.
