A butterfly with a very wide altitude range, often being found at 2000m and sometimes considerably above. It is quite widespread across Europe but rarely more than a few in any one place. The male is a deep blue with the veins marked black and with varying-width strong black borders, and the female plain brown with no marginal lunules. The undersides of both sexes are quite similar, the male is greyish-brown and the female browner, although male undersides can be browner than one might expect. It is slightly larger than the average Common Blue (polyommatus icarus).

 

13342: a male with a dark blue colouring and very strong black borders of constant width.

12567: a male, puddling. The ground colour is a typical pale brown, with a tinge of grey.

7140: a fresh female upperside, plain dark brown and almost completely unmarked. Altitude 780m.

7122: a female underside, with a beautiful clean pale creamy-chocolate ground colour and strong black spots. It unusually has vestigial submarginal marks. Altitude 780m.
