Fun facts
Its cardboard nest is made stronger by a fungus that grows in the walls. The ants feed the fungus, and the fungus holds the nest together.
A big nest has just one queen but up to 15,000 workers.
A new queen cannot start a nest alone. She sneaks into the nest of another ant kind and takes it over.
A sneaky beetle waits by its trails at night and tricks the ants into giving it their food.
When there is danger, it gives off a special smell to warn the other ants.
