Pieris brassicae (Linnaeus, 1758) Large White, Grober Kohlweibling, Pieride du chou, Белянка капустная.
Distribution and biological peculiarities in Armenia: The species is common throughout Europe, North Africa, Asia even through the Himalayas. Armenia is occupied by nominate subspecies, which occupies entire country occurring in many different habitats at the elevation range from 400 to 3000 m a.s.l. The Large White uses wide variety of wild and cultivated Cruciferae as the host-plants, and even considered being a pest, as damages the cabbage harvest. The species gives up to four generations per annum being on wing from mid March till late October, or even early November. Population dynamics: The species is common within most of the habitats, and shows increasing population trend in 2003 -2013 (p<0.05), which is justified by its high-level adaptability and occupation of niches in degraded and transformed habitats.
Conservation measures: The species is not included in the Global, European, and Armenian Red Lists, as well as in CITES and Bern Conventions, which is justified, and the preliminary assessment of its national conservation status suggests Least Concern. The species is distributed in all the Protected Areas, Emerald Sites, and Prime Butterfly Areas, and therefore there is no need for its conservation in the country, however it is important to continue its monitoring, as an indicator of habitat degradation.
