Description in Seitz

''L. damon'' Schiff. (= ''biton'' Sulz.) (81 h). -male large, brilliant shy-blue with a greenish tinge, the margin broadly black, the bright brown underside with or without ocelli, but always with a sharply marked white mesial streak. Female dark brown, above sometimes without traces of reddish submarginal spots. Central and South Europe, throughout Anterior and Central Asia as far as the Tian-shan. – Specimens entirely without ocelli on the hindwing beneath are ab. ''gillmeri'' Krod. (= ''caeca'' Aign.) while individuals with the ocelli distorted into oval spots or streaks, produced by Krodel by low temperature, are ab. ''extensa'' Krod. In ab. ''agraphomaena'' Verity the white streak of the underside is obsolescent, while ab. ''ferreti'' Farre is a dwarfed form of the male with narrow border on the upperside. – Larva greenish yellow, finely and densely hairy, alternately striped with paler and darker green, the head being brownish and the side-line darker or paler ydlow; until June on Esparset. The ants are so much after it that the presence of some larvae in a breeding cage in a room is sufficient to bring into the house whole crowds of ants, which gather about the cages, sometimes as many as ten ants being found on one larva. Pupa ochreous, above greenish, darker along the back. The butterflies occur in July and August on fields of Sainfoin and do not venture far away from them. They are plentiful where they occur.
