It is a butterfly distributed in Europe, especially in the UK, Ireland, and some Nordic countries. Named after their habitat in moist grasslands and marshy areas, they are highly dependent on these specific habitats. Wings usually appear orange and black, and the back of male butterflies' wings has a blue sheen. Larvae feed on specific plants, which is crucial for their survival. Therefore, the distribution of marsh shell butterflies is limited by the habitat of their host plants. Progress has been made in the conservation of marsh mother butterflies in some areas, such as increasing their population through the implementation of specific conservation projects and habitat restoration plans.
