Description in Seitz

Above and beneath rather similar to ''Pseudophilotes baton'' but larger and darker, recognizable by the fringes being very distinctly spotted and the white underside abundantly and heavily spotted with black, the hindwing beneath bearing a bright orange-red submarginal band. Throughout Europe, western and northern Asia, excepting England, the Arctic countries and Japan; from Finland to the Mediterranean islands and from the Atlantic to the Pacific.
*ab. ''nigra'' Gerh. occurs everywhere among ordinary specimens and is the prevalent form in some districts, e. g. in the Valais; differs in the uniformly dark upperside, on which only the discocellular spot is visible
*ab. ''ornata'' Stgr. is very blue above, such specimens being found singly in Europe and as a regular spring form in eastern Asia.
*''orithyia'' Gr.-Grsh. are specimens from the Sinin Mountains in northern Tibet, which form a transition to ''ornata''. The light blue marginal rings characteristic of ''ornata'' being entirely or nearly absent. Egg flattened, white. Larva light green with black head and black spiracles; the first ring, a lateral stripe, the dorsal line and a row of spots on each side of the dorsal line carmine; in the autumn and in the south again in June, on species of ''Sedum''; often guarded by ants. Pupa dirty yellow, greenish at the wing-cases, fastened either on the ground or above it on plants, sometimes a number together. The butterflies in the early spring (emerging in a warm room already in February according to Tumma), and in the south again in August, very local, being absent from large districts, but generally not rare, particularly on chalk in stony places. In China, Korea and Amurland the species is much more generally distributed than in Europe, but always confined to the (rocky) localities of the food plant.
