Distribution and biological peculiarities in Armenia: The species is found in Central Europe and temperate parts of Asia. Armenia is inhabited by subspecies P. d. kotshubeji(Sovinsky, 1915). In Armenia the species is distributed throughout the country, occupying humid parts of calcareous grasslands and sub-alpine meadows at the elevations between 2,000 and 2,700 m a.s.l. In Armenia, the species found to use various Onobrychis spp as the host plant. The flight period of Damon Blue in Armenia is from mid July to mid August depending on elevation.
Population dynamics: The species is slightly uncommon within typical habitat. The population trend during 2003-2013 demonstrates moderate decline. Most probably it is result of overgrazing and uncontrolled mowing. The sainfoins, which are the host plants of the species are also a very desirable fodder for the livestock. At the background of poor rangeland management in the country, the intensity of livestock grazing and mowing is not well controlled which causes habitat degradation and decline of the populations of Damon Blue.
Conservation measures: The species is not included in the Global and National Red Lists, however it was assessed as Near Threatened for the Red Data Book of Butterflies of Europe. The Damon Blue is not included in CITES and Bern Conventions. Preliminary assessment of the species' conservation status for Armenia, suggests it as Near Threatened. The distribution range of the species is covered by number of Protected Areas, Emerald Sites, and Prime Butterfly Areas. Among proposed conservation measures it is suggested to: (1) assess its conservation status for the next edition of Red Book of Animals of Armenia, planned for 2020; (2) develop management plans for the Emerald Sites, where the species is present; (3) start development and introduction of wildlife friendly rangeland management plans, which will touch such important aspects as intensity and spatial pattern of livestock grazing and hay-making, as well as advanced practices, such as rotational grazing, weed suppression and so on.
