Cupido osiris Meigen, 1829 Osiris Blue, Kleiner Alpen-Blauling, Azure de la chevrette ou Azure osiris, Голубянка озирис, Օսիրի կապտաթիթեռ
Distribution and biological peculiarities in Armenia: The species is found in South Europe, Asia Minor, southern Siberia, tha Alay Mountains, Tian-Shan, Dzhungarsky Alatau, the Altai Region, the Sayan mountains, Lake Baikal and Mongolia. The species appears to be monitypic, although there are some variations between local colonies. The Osiris Blue inhabits wide variety of grasslands, including glades and clearings inside forests, and uses wide variety of Legumes as the host plants. Occupying elevation range from about 800 to 2400 m a.s.l., it gives two generations at lower altitude and one at the higher areas. The butterflies are recorded on wing from mid May till late August.
Population dynamics: The species is slightly uncommon to rather common within typical habitat and shows stable population trend during 2003-2013 (p<0.05). Most probably the high level of its adaptability towards host-plant and ability to switch between them, helps the Osiris Blue to survive overgrazing and mowing conditions.
Conservation measures: The species is not included in the Global and Armenian Red Lists, as well as in CITES and Bern Conventions, but is evaluated for the European Red Book as Least Concern. For Armenia the same status is proposed. The Osiris Blue occurs in almost all the Protected Areas, Emerald Sites and Prime Butterfly Areas, so at current there is no need for additional conservation measures, however it is important to continue its monitoring as an essential component of grassland ecosystems.
