Cyrtoclytus capra

UnknownLCEULCEU

Overview

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

The Haarbock faces severe pressure from habitat fragmentation as old-growth forests are cleared for agriculture and urban development across its European range. Climate change compounds these threats by altering the temperature and humidity conditions essential for its host tree species, while invasive forest pests and diseases further degrade the mature woodland ecosystems this longhorn beetle depends upon for reproduction and survival.

Threat summary

Habitat

The Haarbock inhabits mature deciduous and mixed forests, particularly favoring old-growth beech and oak woodlands with abundant dead and decaying timber. This saproxylic beetle requires specific microhabitat conditions found in veteran trees and fallen logs where larvae develop over multiple years.
