This is one of the more tricky species of Blue. It resembles so many of the other species in many different ways but with some experience it can usually be separated easily. The following may help train the eye. It has a generally large feel to it. Markings are bold. It lacks the underside forewing cell spot. The upperside blue is bright and bold. Underside submarginal orange marks extend to the apex of both wings. In space 3/4 of the underside hindwing there is a large white chevron that often extends beyond the post discal spots and points to somewhere just below the cell spot - some other species have this chevron but it is accompanied by others of similar size between the submarginal lunules and the post discal spots.

It flies in southern Europe north to the southern Alps. It has a single brood but can be found throughout the summer in different localities.
