Cossonus linearis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The smalle schorssnuitkever faces severe population declines primarily due to the loss and degradation of old-growth deciduous forests across its European range. Intensive forestry practices that remove dead and dying trees eliminate the species' essential breeding substrates, while forest fragmentation isolates remaining populations. Climate change compounds these pressures by altering forest composition and increasing drought stress on host trees, reducing the availability of suitable bark beetle galleries that this specialized weevil depends upon.
Habitat
This specialized weevil inhabits mature deciduous and mixed forests, particularly those with abundant dead and decaying wood. The species requires the presence of bark beetle galleries in dead or dying trees, where it develops as a predator of bark beetle larvae.
