Distribution and biological peculiarities in Armenia: The species is distributed in Caucasus and Kurdistan. In Armenia the species distributed mostly in Central part of the country occupying slopes of Geghamm Ayots Dzor, Tsaghkunyats, Areguni, and Pambak mountain ridges, as well as hills in Shirak Plateau and Aragats Mountain. Although the species is proposed as monitypic, but isolated populations of the species show high level of morphological differences from each other, and can potentially be a subject of further taxonomic research, thus contributing to genetic diversity. Nina's Blue inhabits calcareous mountain steppes with dominating legume plants, occurring between 1500 to 2300 m a.s.l. Flight period in Armenia is mainly from late July to mid August, lasting until end of August, in single generation. In Armenia the larvae develop on Astragalus brachycarpus and Astragalus subrobustus. The hibernating stage is a first instar larvae. Population dynamics: In Armenia the species is rather common within a typical habitat, however it shows moderate declining population trend (p<0.05). The main cause of the decline is most probably overgrazing, since increased load on the grasslands can eliminate number of the herbaceous host plants. Additional damage to the habitat is caused by the feet of livestock, which is especially noticeable at the hill-type of the habitat. From another side, high level of species' specialization doesn't allow switching the host plant into more resistant Astragalus species.
Conservation measures: The species is not included in the Global and European Red Lists, as well as in Appendices of Bern and CITES Conventions. Some populations of the species are protected in Khosrov Nature Reserve, and partly in Gnishik Protected Landscape and Lake Sevan National Park, and are popularized through the following Prime Butterfly Areas: Artanish-Shorzha, Ourtsadzor, and Gnisheek. In addition some other parts of the species' range are covered by the following Emerald Sites protected under Bern Convention: Djadjur, "Sevan" National Park, Akhuryan Reservoir, "Khosrov Forest" State Reserve, Arai Ler, and Gnishik; however the protection regime in most of these areas is still requires further development, due to lack of management plans. The proposed conservation measures should address: (1) inclusion of the species distribution patches in Aragats and Tsakhkounyats Mountains into Emerald Network; (2) development of management plans for existing Emerald Sites; (3) adoption of the species/land friendly practices of livestock husbandry in the priority areas; (4) use of this charismatic species for development of butterfly-watching and therefore for support of local communities, which can benefit from tourists' flow.
