A butterfly with a very wide altitude range, often being found at 2000m and sometimes considerably higher. It is quite widespread across Europe but usually not more than a few in any one place. The male is a deep strong 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 blue-grey to 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).|
