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 ants of the genera Crematogaster, Camponotus, and Tapinoma. The Anomalous Blue has one generation a year and hibernation takes place on the ground, the small caterpillars hiding under stones.
