Distribution and biological peculiarities in Armenia: The species is distributed in Southern Europe, Asia Minor, Caucasus, and Transcaucasia. Armenia is inhabited by P. d. armena (Staudinger, 1871) an endemic Caucasian subspecies. The Turquoise Blue inhabits meadows and humid steppes at elevation range from 2000 to 2800 m a.s.l. however with some gravel-like cover of slopes, as the host plant of the species in Armenia - Anthyllis spp., likes those kinds of screes to grow. In Armenia the species flies from mid June till late July, sometimes - early August.
Population dynamics: The species is uncommon within typical habitat, and shows moderately declining population trend during 2003-2013 (p<0.05). It appears that the species is affected by overgrazing and uncontrolled mowing.
Conservation measures: The species is not included in the Global and Armenian Red Lists, as well as not included into CITES and Bern Conventions. Meanwhile it was assessed for the European Red Book as Near Threatened. Preliminary evaluation of Turquoise Blue's conservation status for Armenia suggests the same - Near Threatened. At current the species' distribution is partly covered by Zangezur Biosphere Complex, Gnishik Protected Landscape, Lake Sevan and Lake Arpi National Parks as well as by several Emerald Sites. The species is presented in Lichk, Kajaran, Gnisheek, and Artanish-Shorzha Prime Butterfly Areas. To protect the species it is necessary to: (1) include it into next edition of Red Book of Animals of Armenia; (2) develop management plans for the Emerald Sites, where the species occurs; (3) develop and launch habitat friendly grazing and mowing schemes. Also it is important to mention that the species is quite interesting for European butterfly-watchers and therefore can be used as one of the flagships to attract wildlife-tourists thus creating alternative income opportunities for the local rural inhabitants, and obtaining their support in species and habitat conservation.
