There is even an insect called the antlion that builds a trap nest similar to an ant's. The nest lures ants to its opening, where the antlion awaits it with gaping jaws. Ants may very well compete with members of their own species, regardless of color. In fact, it is more likely that these ants will attack their own species since they get food from a common source. This is why soldiers are essential parts of any colony.
Termites look and act like ants.
This is untrue. In fact, termites belong to a completely different order. However, they are incredibly similar in many ways. This phenomenon is called convergent evolution. The true relatives of the ant are bees and wasps.
