de pucerons des racines en captivité ?","Non. Dans la nature, les ouvrières vivent surtout du miellat de pucerons des racines qu'elles soignent dans leurs galeries, ce qui explique qu'on les voie rarement à la surface.

Une étude de terrain a montré que les monticules protégés du soleil direct restaient beaucoup plus frais, probablement assez pour ralentir le développement et la reproduction de la colonie. Ces monticules sont faits surtout de terre et produisent peu de chaleur par eux-mêmes : les fourmis dépendent donc du soleil, ce qui explique que les monticules se trouvent dans des prairies ouvertes et ensoleillées et puissent durer de nombreuses années.",{"question":226,"answer":227},"Combien de temps peut vivre une reine de Lasius flavus ?","Très longtemps. Un record de laboratoire de 22,5 ans est signalé pour une reine de Lasius flavus, parmi les plus longues durées de vie enregistrées chez les reines de fourmis. Une colonie en bonne santé peut donc durer de nombreuses années.","De petites ouvrières d'un jaune clair à jaune brunâtre, aux yeux minuscules, qui vivent presque entièrement sous terre ou sous les pierres dans l'herbe. Contrairement à Lasius umbratus, qui lui ressemble, elles n'ont pas de poils dressés sur les scapes des antennes ni sur les tibias.
