Tetraplodon blyttii

UnknownENEUENEU

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Tetraplodon blyttii faces severe population decline primarily due to habitat degradation from atmospheric pollution and climate change affecting its specialized moss substrates. The species' dependence on specific bryophyte communities makes it particularly vulnerable to environmental changes that alter moss composition and distribution. Nitrogen deposition from industrial activities disrupts the delicate chemical balance required for its survival, while warming temperatures threaten the cool, humid conditions essential for both the moss and the beetle.

Threat summary

Habitat

Tetraplodon blyttii inhabits specialized moss communities, particularly those growing on decaying organic matter in cool, humid forest environments. The species is closely associated with specific bryophyte species that provide both food and breeding substrates in northern temperate and boreal regions.

Frequently asked questions

Why is Tetraplodon blyttii classified as Endangered?
Tetraplodon blyttii is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Tetraplodon blyttii faces severe population decline primarily due to habitat degradation from atmospheric pollution and climate change affecting its specialized moss substrates. The species' dependence on specific bryophyte communities makes it particularly vulnerable to environmental changes that alter moss composition and distribution. Nitrogen deposition from industrial activities disrupts the delicate chemical balance required for its survival, while warming temperatures threaten the cool, humid conditions essential for both the moss and the beetle.
Where does Tetraplodon blyttii live?
Tetraplodon blyttii occurs in Norway, and Sweden. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
