I had labelled the second pic as Turquoise Blue for two years without realising it was wrong. What did mislead me was the little orange lunules on the underside. I read in the books that it is a distinctive feature of TB and didn't pay attention to anything else.Looking at them side by side I think it is clear the second Blue isn't a TB but a Lysandra of some kind. What enfuriates me is that I didn't take a pic of the upperside. I remember it was quite a vivid blue and assumed that was the confirmation of it being a TB. Silly me.That second Blue was photographied in the Pyrenees (Huesca province) in August 2007. As far as I know the only Lysandra that can be found at that altitude is Chalk-hill Blue. I know they are very variable from one area to another in Spain. This is another prove of how confusing the Lysandra species can be here.</blockquote>
