Nice male and female Chalk hill Blues here Bryn.

There are many "ways" to tell the difference between Chalk hill Blues and Common Blues, but the most simple way is - The Common Blue has a plain fringe (around the wings)...the Chalk hill Blue (like the Adonis Blue) has a chequered fringe around the wings.

Examples.
Male Common Blue. Look at the plain white wing fringes (no black lines to fringes).
