Anthribus scapularis

Local name: porssköldlusbagge

Unknown

Overview

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

Anthribus scapularis faces severe population decline primarily due to the loss and degradation of old-growth deciduous forests across Scandinavia. The species' dependence on specific fungal associations in decaying hardwood, particularly oak and beech, makes it extremely vulnerable to modern forestry practices that remove dead wood and favor coniferous plantations. Climate change compounds these pressures by altering fungal communities and shifting suitable habitat northward faster than the species can adapt.

Threat summary

Habitat

This specialized weevil inhabits mature deciduous forests, particularly those dominated by oak and beech trees with abundant dead wood and fungal growth. The species requires specific microhabitats within decaying hardwood where it feeds on fungi, making it highly dependent on forest ecosystems that maintain natural decay processes.

Frequently asked questions

Why is porssköldlusbagge classified as Vulnerable?
porssköldlusbagge is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Anthribus scapularis faces severe population decline primarily due to the loss and degradation of old-growth deciduous forests across Scandinavia. The species' dependence on specific fungal associations in decaying hardwood, particularly oak and beech, makes it extremely vulnerable to modern forestry practices that remove dead wood and favor coniferous plantations. Climate change compounds these pressures by altering fungal communities and shifting suitable habitat northward faster than the species can adapt.
