Numerous anthills are present in the forest area. Anthills are composed of accumulated vegetable detritus.. The principal rôle of the dome is the thermoregulation of the anthill, in particular for the brood. In fact, the temperature of the ants’ eggs must not go above 25°-30°C. The weight of this habitat can be amazing: up to 20 kilos for a nest of 3 m cubed.. Apparently anthills are a sign of a healthy environment. So please respect these little creatures!
