She emits a secretion from the Dufour's gland on her abdomen, named after its discoverer, Léon Jean Marie Dufour, which includes a pheromone which subdues the attacked ants and makes them less aggressive.
Like other Servifusca, this species is subject to raids by dulotic species such as Formica sanguinea and Polyergus rufescens where their ranges coalesce.
