Distribution and biological peculiarities in Armenia: The species is distributed in Iran, Turkey, Southern Transcaucasia, and Kopet-Dagh. It is monotypic and is found in Armenia only at the high zone of Aragats Mountain, where it inhabits grass carpets alternated with screes and taluses. The elevation range therefore is from 2900 to 3200 m a.s.l. The host plant of the species is Arabis caucasica. The Bowden’s White gives a single annual generation, flying from mid July to mid August.
Population dynamics: The species is somewhat common in the typical habitat and in 2003-2013 demonstrates stable population trend (p>0.05), however with quite strong negative fluctuations, which are probably resulted by weather conditions of some unfavorable years exacerbated by extreme conditions of high-mountains.
Conservation measures: The Bowden’s White is not included in the Global and European Red Lists, but it is the only representative of Pieris genus included in the Armenian Red Book, where it is listed as Critically Endangered. Although the Red Book states the overgrazing, as one of the threats for the species, it hardly could be so, as the livestock rarely grazes at such elevation. However, this narrow-ranged species could potentially by affected by climate change, which results in shrinking of the alpine zone. The distribution of Bowden’s White is partly protected by Aragats Alpine Sanctuary and the Emerald Site of the same name. At current, it is important to develop a management plan for the Emerald Site, which can support protection of this species as well. Also it is very important to continue the monitoring of the species, with a main aim of determination changes in its population trend.
