Description:
The Anomalous Blue occurs in woodland clearings, open scrub, on sheltered slopes and in agricultural areas. All the places are warm and have a flower-rich grassy vegetation.
The females lay their eggs on the flowers of Sainfoin (Onobrychis viciifolia) and Cockscomb Sainfoin (O. caput-galli).
The caterpillars are attended by different kinds of ants. The Anomalous Blue has one generation a year and hibernation takes place on the ground, the small caterpillars hiding under stones.
