Common or Chalkhill?

[Wurzel]

I found this battered looking female blue at Martin Down on Sunday morning and at first I thought it was a Common Blue due to the wear on the wings, but the lack of orange lunules on the forewing underside suggested it could be a Chalkhill? Any help would be greatly appreciated...

Cheers

With no real rationale for it, it looks more like a female Chalkhill to me. Especially the second shot.

I agree.

In the second picture you can see the dark chequering on the outer half of the fringe, near the apex. Common blue only ever shows chequering on the inner half of the fringe. The colours are right for chslkhill, too.

Cheers for that Dave and Guy!
My gut was agreeing with you but I've been burnt on some id's before so it's always a good idea to check

Have a goodun
