Cossonus parallelepipedus

Local name: större vedvivel

Unknown

Overview

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

The större vedvivel faces severe population decline due to the loss of old-growth deciduous forests containing its essential host trees, particularly ancient oaks and beeches with extensive dead wood. Modern forestry practices that remove fallen logs and standing dead trees eliminate the beetle's breeding habitat, while forest fragmentation isolates remaining populations. Climate change compounds these pressures by altering forest composition and reducing the availability of suitable microhabitats within decaying wood.

Threat summary

Habitat

This weevil species inhabits old-growth deciduous forests, particularly those dominated by oak and beech trees with abundant dead wood and fallen logs. It requires specific microhabitats within decaying heartwood of large diameter trees, where larvae develop over multiple years in the moist, fungus-rich environment.
