Leioderes kollari

UnknownLCEULCEU

Overview

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

The lönnbock faces severe pressure from the ongoing loss and fragmentation of old-growth deciduous forests across its European range. Climate change compounds these threats by altering the composition of forest ecosystems and reducing the availability of suitable host trees. The species' dependence on specific microhabitat conditions within mature forest stands makes it particularly vulnerable to logging activities and forest management practices that favor younger, more uniform tree stands.

Threat summary

Habitat

The lönnbock inhabits mature deciduous and mixed forests, particularly those dominated by maple, beech, and oak trees. This longhorn beetle requires old-growth forest conditions with dead and dying wood, where larvae develop in the decaying timber of broadleaved trees.
