Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and Mediterranean forests and woodlands within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Belgium, France, Netherlands, Norway, and United Kingdom. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Barred Sailor

The common barred sailor (<em>Neptis laeta</em>) is a butterfly belonging to the family Nymphalidae, found in terrestrial and freshwater habitats across its range. It is classified as Least Concern on the IUCN Red List, suggesting the species is not currently facing significant threats to its population. Like other members of the genus <em>Neptis</em>, the common barred sailor is typically characterized by striking dark wings adorned with white banding, giving it a distinctive sailor-like appearance. These butterflies often inhabit forest edges, woodland clearings, and areas with abundant larval host plants. Adults are often observed gliding and sailing on forest paths and sunlit openings, a characteristic flight pattern of the genus. The larvae typically feed on specific host plant species, and the species life cycle includes egg, larval, pupal, and adult stages. Biological traits of this species remain poorly documented in the scientific literature.

Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
