OK left the ID as Unknown for the time being.

Thanks Kostas. The thing that bothers me is that there seems to be only 4 spots on the forewing of the Polyommatus icarus - http://www.learnaboutbutterflies.com/Bri..., while they cover the whole forewing in my spotting! - http://en.wikipedia.org/wiki/Northern_Br.... That what made me decide...
Any further comments Kostas, cos I don't know Europesn butterflies at all...

Sorry, Pam, I promised you to take another look on this one, but it is already 1 year ago...
Personally I do not think it is Aricia artaxerxes. But is it really Polyommatus icarus, as suggested bei Kostas? As I commented below, at first sight it looks like being a female Common Blue, but these Blues are tricky to confirm without a ventral view. I check later again.

I think it's a Polyommatus icarus (female)

OK, I certainly will help, but I need much more time, quite busy... And this one is also a tricky one... First sight easy, second sight... Hmmm...

i'm a beginner too - maybe we could ask bayucca - he's really an expert !

wow, thanks Martin, they really do look similar, and I'm really just a beginner IDing butterflies, so it's hard to tell... I'll see if anyone else comments.

they really look very similar but i think you're right - there are differences like the shape of the fore-wing - they are more roundish while common blue's have a more linear shape - maybe you'd like to compare it with one of which i'm quite sure it is a common blue female - http://www.projectnoah.org/spottings/128...

^^ yeah i know.... just as if they didn't want to pose for a photo....

@ martinUrban, sometimes those little fellows just won't oblige by closing their wings, even though I follow them for some time! Do you still have some doubt about the ID?

MartinUrban

I guess that's it... by seeing the Backside of the wings it's easier to identify...

thanks MartinUrban. Was looking through the Butterflies of Europe photos and found this. Seems to match. What do you think?
