Thank you for letting me join UK Butterflies
Please can you identify the attached butterfly?

It's either a female Chalkhill or Adonis Blue, assuming it was seen in the UK. A site name might be useful as Chalkhills are more widespread.

My instant reaction was that this is a Chalkhill Blue female (rather than Adonis). It's something relating to the marginal spotting that just doesn't seem right for Adonis - in fact, if you look closely there are "silver studs" in these spots which is something I have only ever seen on Chalkhill females (of these two species).

Thank you,
I now think this is a female Chalkhill Blue, the silver spots were confusing me as I have only seen them before on Silver Studded Blues.
