Multiple Langton's ants can co-exist on the 2D plane, and their interactions give rise to complex, higher-order automata that collectively build a wide variety of organized structures. 

There are different ways of modelling their interaction and the results of the simulation may strongly depend on the choices made.<ref>{{cite journal | last1=Belgacem |first1=S. |last2=Fatès |first2=N. | title=Robustness of Multi-agent Models: The Example of Collaboration between Turmites with Synchronous and Asynchronous Updating |journal=Complex Systems |date=2012 |volume=21 |issue=3 |pages=165–182 |doi=10.25088/ComplexSystems.21.3.165|url=https://hal.inria.fr/inria-00462438/file/AsynchRobustnessTurmites.pdf }}</ref>

Multiple turmites can co-exist on the 2D plane as long as there is a rule that defines what happens when they meet. [[Ed Pegg, Jr.]] considered ants that can turn for example ''both'' left and right, splitting in two and annihilating each other when they meet.<ref>{{Cite web | last = Pegg, Jr. | first = Ed | title = Math Puzzle | url=http://www.mathpuzzle.com/26Mar03.html | access-date = 15 October 2009 }}.</ref>
