Polyommatus nivescens Keferstein, 1851

Host plants:
Anthyllis

Habitat:
Polyommatus nivescens colonizes habitats such as rocky grasslands, bushy slopes and ravines.

Life cycle:
The butterflies occur in a single generation from late May through August. The caterpillar overwinters.

Remarks:
Polyommatus nivescens is found almost exclusively in Spain from the Sierra Nevada to the Pyrenees (from 1000m above sea level and above). A record refers also to the French Pyrenees, where presumably some populations will be found especially in the east.
