Overview

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

Formicoxenus provancheri faces significant threats from habitat fragmentation and loss of its specialized boreal forest ecosystems. As an obligate social parasite dependent on specific host ant species, particularly Myrmica ants, any disruption to host populations directly impacts this species' survival. Climate change poses additional risks by altering the delicate ecological balance required for both the parasite and its hosts to coexist successfully.

Threat summary

Habitat

This species inhabits boreal and mixed coniferous forests across northeastern North America, where it lives as a social parasite in the nests of Myrmica ant species.
