Which ant species is recognized for having a prominent queen and can be hostile toward other ants?

The Imported Fire Ant is known for having a clearly defined hierarchy within its colony, including a prominent queen. This species exhibits aggressive behavior, particularly when its nest is disturbed. Fire ants are notorious for their hostile interactions not only with other ant species but also with other animals and humans, defending their territory aggressively. Their ability to mobilize a large number of worker ants to protect the colony makes them formidable opponents in their environment. Other ant species listed do not typically demonstrate the same level of aggression or have as notable a queen presence as the Imported Fire Ant.
