European Sundew Plume Moth, European Sundew Plume

The European Sundew Plume Moth is a small, pale moth belonging to the Pterophoridae family, recognisable by the characteristic feather-like division of its wings into narrow plumes, a trait shared by other "plume moths." Its life cycle is unusually specialised: larvae feed exclusively on sundews (*Drosera* species), carnivorous plants adapted to nutrient-poor, waterlogged soils. This obligate relationship makes the moth an indicator species for healthy sundew populations and, by extension, for the wetland ecosystems that support them. Adults are nocturnal and rarely observed, contributing to limited data on their behaviour and abundance.

The species has a wide but fragmented distribution across Europe, with records extending from the United Kingdom and Ireland through Scandinavia (Finland, Sweden, Norway, Denmark), continental Europe (Netherlands, Germany, Belgium, Luxembourg, France, Austria, Poland, Estonia, Slovakia, Serbia), Russia, and reportedly Japan and Australia. It is confined to terrestrial habitats where sundews grow, principally bogs, fens, and other acidic wetland environments.

No specific threats have been formally assessed for this species, and population trends remain unknown. However, its dependence on sundew-rich wetlands suggests vulnerability to habitat degradation, drainage, and peatland loss, pressures known to affect these host plants across its range.

No targeted conservation measures have been documented for this moth specifically, though protection of bog and fen habitats in several range countries may incidentally benefit it.

Given the IUCN Critically Endangered listing alongside an "unknown" population trend and unassessed threats, the species' status reflects a significant data gap rather than confirmed decline. Further survey work is needed to clarify its actual conservation trajectory.

Buckleria paludum inhabits wetland environments including bogs, marshes, and other areas with standing or slow-moving water. The species requires specific wetland vegetation that serves as host plants for larval development and adult feeding.
