Overview

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

Stor barktæge (Aradus conspicuus) faces severe population declines due to habitat loss and degradation of its specialized bark beetle-dependent ecosystems. The species' narrow ecological requirements and limited dispersal ability make it particularly vulnerable to forest fragmentation and changes in host tree availability.

Threat summary

Habitat

Inhabits mature coniferous and mixed forests, particularly those with high densities of bark beetles and dead or dying trees. The species is closely associated with old-growth forest ecosystems where it feeds on bark beetle larvae beneath tree bark.
