svartstrimmad vedharkrank

Phoroctenia vittata

Unknown

Overview

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

Phoroctenia vittata faces significant pressure from deforestation and habitat fragmentation across its Scandinavian range, where old-growth coniferous forests are increasingly converted for timber production. Climate change poses an additional threat by altering the moisture and temperature conditions essential for the fungal communities this beetle depends upon. The species' specialized ecological requirements and limited dispersal ability make it particularly vulnerable to landscape-level changes in forest management practices.

Threat summary

Habitat

This specialized beetle inhabits old-growth boreal and temperate coniferous forests, particularly those dominated by spruce and pine. It requires dead and decaying wood with specific fungal associations, typically found in undisturbed forest environments with high moisture retention.
