Overview

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

The Sawyer Beetle faces severe population declines due to widespread habitat loss from deforestation and urbanization, which eliminates the mature deciduous forests it requires for breeding. Climate change is altering forest composition and reducing suitable host tree species, while intensive forest management practices remove the dead and dying wood essential for larval development.

Threat summary

Habitat

Mature deciduous and mixed forests with abundant dead and decaying hardwood trees, particularly oak, beech, and other broadleaf species. Larvae develop in rotting wood and root systems of dying or recently dead trees in established forest ecosystems.

Frequently asked questions

Why is Sawyer Beetle classified as Critically Endangered?
Sawyer Beetle is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. The Sawyer Beetle faces severe population declines due to widespread habitat loss from deforestation and urbanization, which eliminates the mature deciduous forests it requires for breeding. Climate change is altering forest composition and reducing suitable host tree species, while intensive forest management practices remove the dead and dying wood essential for larval development.
Where does Sawyer Beetle live?
Sawyer Beetle occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
