Distribution and biological peculiarities in Armenia: The species is found across Europe, and eastwards into temperate Asia as far as Japan. Armenia is inhabited by nominate subspecies. The Orange Tip is widely distributed throughout the country occupying deciduous forests, meadows, steppes, and riparian forests and orchards located in the dry areas. Elevation range of the species varies from 800 to 2300 m a.s.l. The species grows on a wide variety of host plants from the Cruciferae family: Cardamine pratensis, Alliaria petiolata, Thlaspi arvense, Turritis glabra, Capsella bursa-pastoris, Sisymbrium sp., and others. The butterflies are on wing from early April to early July depending on elevation.
Population dynamics: The species' abundance varies from common in the forests to slightly uncommon in open landscapes. Population trend of the Orange Tip in Armenia during 2003-2013 demonstrates stability (p>0.05). It appears that wide spectrum oh the species' host plants allows it to adapt under different stressing conditions and habitat changes.
Conservation measures: The species has not been evaluated for the Global and National Red Lists; but it is included in the Red Book of European Butterflies as Least Concern. Also the species is not included in the Appendices of CITES and Bern Conventions. The preliminary evaluation of the species' conservation status suggests it as a Least Concern. Its distribution is covered by almost all the protected areas and Emerald Sites; also it occurs in most of the Prime Butterfly Areas. At current there are no conservation measures required; however it is important to track the population trend of the Orange Tip along with other early spring butterflies.
