Habitat & Geographic Range

cloaked pug

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (8 countries).

Laysan Duck

Habitat

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.

cloaked pug

The cloaked pug (Eupithecia abietaria) is a geometrid moth in the family Geometridae found across boreal and montane Europe, with populations extending from Scandinavia through the Alps and Carpathians into central Siberia. The adult wingspan measures approximately 20–25 mm, with the intricate grey, white, and dark cross-banded pattern typical of pug moths providing superb camouflage against spruce bark and lichen-covered surfaces. The species is closely associated with Norway spruce (Picea abies) and related conifers, whose developing cones serve as the principal larval foodplant. Larvae feed within the scales of ripening cones, making detection and study challenging. Adults fly in a single generation from June to August, active at night and attracted to light. The cloaked pug is characteristic of mature boreal coniferous forest and montane spruce woodland, habitats that have declined in extent across parts of Central Europe due to conversion to plantation forestry and changing forest management practices. Its conservation depends on the maintenance of naturally structured boreal and subalpine forests with abundant cone-bearing conifers.

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.
