Habitat

Inhabits forested and woodland environments where dead wood is available for nest construction. Primary colonies are established in decaying stumps, fallen logs, and hollow trees with high moisture content. Satellite colonies may occur in moist wood of human structures.

Distribution

to western North America.

Ecological Role

Functions as a decomposer and recycler of dead plant material through excavation and of decaying wood. Contributes to nutrient cycling in forest .

Human Relevance

May establish satellite colonies in moisture-damaged wood of human structures, potentially causing structural damage. Not a primary pest but requires management if occur in buildings.
