Formica cunicularia

Formica cunicularia is a striking species within the Formica family.Predominantly found throughout Europe and parts of Africa and Asia, they are a frequent target for parasitic species. Their nests, characterised by small earthen mounds, are typically located in sparse woodlands or open areas, favouring sunny locations. Commonly known as tunnel ants, they utilise heat and a network of narrow tunnels to manage brood development down to the water table for essential moisture and nourishment. Predation by species such as Formica Sanguinea and Rufa has led them to develop notably aggressive behaviour in their natural habitat. They actively hunt both live and dead prey. Additionally, Formica cunicularia nurtures and cultivates aphids to harvest their sweet honeydew.
