Red wood ant - Formica rufa - Inhabits mainly coniferous and mixed forests
The anthill is up to 1 m high, sometimes even more. They build their nests in the shape of a dome, thanks to which the anthill is able to accumulate more solar energy. From the chambers located in the upper part of the anthill, numerous corridors lead to its surface. One anthill can house up to 100,000 ants.
