Underside. A really magnificent coloured blue this one, it produces a turquoise sheen when the light is angled right. Also the black veins leading to the edges of the wings are a give-away. This is a rare species in the UK. It is confined to just a few hot areas in southern UK where the grass is very short (often cropped by rabbits) and their foodplant Horseshoe Vetch grows.

The bottom picture is taken in Valais, the top in Dorset, UK.
