Sie mag trockene, offene und leicht beschattete Orte wie Hecken, Waldränder, Heiden, Lichtungen und Stadtränder, und ihre Kolonien sind meist bescheiden groß, von einigen Hundert bis etwa 2.000 Arbeiterinnen.",{"question":255,"answer":256},"Was frisst Formica fusca in der Natur?","Die Arbeiterinnen jagen allein kleine Insekten und trinken außerdem den Honigtau von Blattläusen und den Nektar von Pflanzen. Sie können eine Blattlauskolonie lange besetzt halten und verteidigen, nutzen kurzlebige Nahrungsquellen schnell aus und nehmen manchmal sogar Lasius-niger-Arbeiterinnen auf dem Heimweg das Futter ab.","Mattschwarze bis dunkelgraue Arbeiterinnen mit bräunlichen Beinen, die schnell laufen und allein auf Futtersuche gehen. Sie sind größer und langbeiniger als Lasius niger und weniger silbrig als Formica cinerea. Formica lemani sieht fast genauso aus, und nur unter dem Mikroskop (anhand der Haare auf dem Pronotum und an den Beinen) lassen sich die beiden unterscheiden.
