Distribution and biological peculiarities in Armenia: The species is distributed in Caucasus, Transcaucasia, and Central Asia. In Armenia the subspecies K. z. ordubadi (Forster, 1938) is recorded inhabiting calcareous grasslands of Southern Armenia at the elevation range from 1000 to 2400 m a.s.l. Preliminary it is thought that there is a dividing of the country by K. zephyrinus and K. sephirus, and that the only spot where these species have been recorded together is Khosrov Forest State Reserve, however the hypothesis requires further confirmation. There are several Astragalus species, which are used by Zephyrinus Blue as host plants, such as A. vulpinus and some others. The species has one annual generation, having butterflies on wing from early May till mid July depending on elevation.
Population dynamics: The species is uncommon to rare within typical habitat, and demonstrates stable population trend in 2003-2013 (p>0.05). Being a habitat specialist it could potentially be affected by overgrazing, however the real trend might require longer period of monitoring.
Conservation measures: The species is not included in the Global, European, Armenian Red Lists, as well as in CITES and Bern Conventions. Preliminary evaluation of its National conservation status suggests it as a Least Concern. The current distribution range of Zephyrinus Blue is covered by Zangezur Biosphere Complex, Gnishik Protected Landscape, and Khosrov Forest State Reserve. Also it is presented in Prime Butterfly Areas Gyumorats, Kaladash, Gudemnis, Lichk, Kajaran, and Gnisheek. At current there is no necessity for special conservation measures, however it is important to continue the species' monitoring for determination of longer-term population trend, and timely development of appropriate measures.
