The Chequered Blue, a small but conspicuous butterfly, can be seen on warm, and rocky slopes and narrow ledges, where there is little vegetation, apart from its foodplants White Stonecrop (Sedum album) and Orpine (Sedum telephium). The females lay their eggs on the leaves of the foodplant near the stem. The caterpillars are often found with different ants. The pupa overwinters, and is often hidden under stones or in small hollows in the ground near the foodplant. The Chequered Blue produces one or two generations a year, depending on its geographical position.
