Bull ant is the largest ant in the world. It lives in Queensland, Australia and northern New South Wales, and is more powerful than desert ants. The worker ant of this rare ant species is 3.7 cm, which is really as big as a cockroach. Although their bodies are long, they are not very stupid as a whole, because the long maxilla accounts for a large part.

Cattle ants are fierce. They have sharp serrated jaws and hard thorns, and dare to fight against any enemy who gets in the way. It may be because the pain caused by their stings is only temporary, not as deadly as bulldog ants, and locals often classify them with other stinging insects. After being stung, locals can poke some leaves and apply them to the wound to relieve the venom. Therefore, it is only recorded that their acupuncture will cause pain, and there is no record of toxicity.
