Formica sanguinea y Polyergus rufescens asaltan sus nidos para llevarse pupas y crían como ayudantes a las obreras que nacen de ellas, y todas las especies del grupo fusca de Fenoescandia se han encontrado en colonias mixtas con Formica sanguinea.

Le gustan los lugares secos, abiertos y con algo de sombra, como los setos, los bordes del bosque, los brezales, los claros y las afueras de las ciudades, y sus colonias suelen ser modestas, de unos pocos cientos a unas dos mil obreras.",{"question":254,"answer":255},"¿Qué come Formica fusca en la naturaleza?","Las obreras cazan pequeños insectos por su cuenta y también beben la melaza de los pulgones y el néctar de las plantas. Pueden ocupar durante mucho tiempo una colonia de pulgones y defenderla, y aprovechan enseguida las fuentes de alimento efímeras, a veces incluso quitándoles la comida a las obreras de Lasius niger que vuelven al nido.","Obreras de un negro mate a gris oscuro, con las patas pardas, que corren rápido y forrajean solas; son más grandes y de patas más largas que Lasius niger y menos plateadas que Formica cinerea. Formica lemani es casi idéntica y solo un microscopio (los pelos del pronoto y de las patas) permite distinguirlas, así que una colonia vendida como Formica fusca es solo la mejor suposición dentro del grupo fusca, y esta ficha describe la especie en sentido estricto.","es",{},true,[261,264,267,269],{"kind":262,"text":263},"tip","Dale al nido una cámara húmeda y mantén seca la zona de forrajeo.
