 There are more than 8,000 species of ants worldwide, and here in the southeast, where you might find the Tawny Crazy Ant, you might confuse it with another ant. There are five species that would most likely confuse with the Tawny Crazy Ant, those would be the Acrobat Ant, the Pyramid Ant, the Argentine Ant, the Dark Grove Rant, and the Otarous House Ant. So the Argentine Ant is probably the ant that is most misidentified as a Crazy Ant. They occur in the same habitats as Crazy Ants. The Argentine Ant is more of a gray color. The Tawny Crazy Ant is more of a brownish color. The Acrobat Ant has an abdomen that is kind of heart shaped and cares its abdomen up in the air. That's where it gets its name, Acrobat. The Crazy Ant has a more of a straight cylindrical abdomen. The Tawny Crazy Ants are tawny colored, more of an off brown or caramel colored, and your Acrobat Ants will be almost black in color. If you see an inverted volcano nest in sandy areas, that is a Pyramid Ant. The physical differences between Pyramid Ants and Tawny Crazy Ants would be the Pyramid Ants might be, they come in different colors, but the ones we have here in the southeast that you might confuse with the Tawny Crazy Ant would be either orangish color. We have some that are black in color, but they're not typically the same color as that tawny color, that brownish kind of off caramel color of a Crazy Ant. One of the other ants that might be more commonly confused with a Tawny Crazy Ant would be something called a rover ant, a dark rover ant. It is a pest species, a very, very small ant, maybe half the size of a Tawny Crazy Ant. The populations are not that large, they do trail in really tight trails, but where you might have a lot of Crazy Ants in a trail, maybe half an inch wide where there would be solid ants along that trail. With a dark rover ant, you might have an ant every inch. There's an ant in the southeastern U.S., more common along the East Atlantic states called the Otaris house ant. It is about the same size as a Tawny Crazy Ant, but it's black. They have glands that they use in protection, have this peculiar odor that I think they smell like suntan lotion. Again, the numbers won't be as high as you might see in a Tawny Crazy Ant infestation. One of the best ways to define, to differentiate between a Tawny Crazy Ant and any other ant species is just the sheer number of ants. There's huge populations of dead ants that might congregate around the structure.
