It is found in the Palearctic region, specifically in Southwest Europe, Algeria, Morocco, and Tunisia. Male and female individuals of this butterfly look identical. The underside of its wings is green, while the upperside is greyish brown. The green wing underside is marked by a mediodiscal white line, which distinguishes this species from the closely related Callophrys rubi.
