Toso and Balletto, 1976
Piedmont Anomalous Blue
Description:
The Piedmont Anomalous Blue occurs on warm, dry, rocky slopes with groups of bushes and patches of grassy, species-rich vegetation, where nectar is in good supply.
The female lays her eggs on Mountain Sainfoin (Onobrychis montana) and Sainfoin (O. viciifolia). The caterpillars feed on the flowers, and when still small, hibernate. In the spring, they are attended by ants.
Habitat:
