Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
The mörk nästingbagge (Choragus horni) faces severe population declines due to habitat loss and degradation of its specialized fungal microhabitats. This small weevil's dependence on specific fungal associations in decaying wood makes it extremely vulnerable to forest management practices and climate-induced changes in fungal communities.
Key Facts
Habitat & Distribution
Inhabits mature coniferous and mixed forests where it lives in association with fungi growing on decaying wood, particularly in dead branches and fallen logs. Requires specific microhabitat conditions with appropriate moisture levels and fungal communities.
