Camponotus intrepidus is a striking and impressive ant species native to Australia. Known for its large size, this species rivals the famous Myrmecia in physical presence while maintaining a docile temperament. They build unique and elaborate nests, characterized by large earthen mounds with chimney-like entrances. These ants are nocturnal, coming out after dark unless disturbed, and their intricate behaviors make them a captivating choice for ant enthusiasts.

In the wild, Camponotus intrepidus constructs expansive soil mound nests, often incorporating materials like charcoal, leaves, and twigs into a thatched covering. This layer helps protect the nest from rain and erosion. Their nests are typically elliptical and peaked, with a mean height of 20.4 cm and varying in ground-surface area from 0.05 to 1.19 m².
The entrances to these nests are chimney-like structures, barely wide enough for a single worker to pass through, making them inconspicuous. Most of the galleries are located within the mound and the upper layers of soil, though some extend deeper into the clay subsoil. These chambers and galleries are lined with organic material, including leaves and rootlets, forming a distinctive glazed texture.
The mounds are often drier than surrounding soils, as confirmed by moisture measurements, and are typically shaded by shrubs or trees. Despite their impressive structures, Camponotus intrepidus does not significantly contribute to soil mixing compared to smaller ant species like Aphaenogaster longiceps.
