There is another interesting structural phenomenon built by ants, mass graves. I have first hand observed that when a ant pile/mound is damaged (pour water on the mound, spray with ant poison, or just kick the mound), the ants over the next few days will simultaneously rebuild the original structure and relocate the dead ants to a newly build structure. Though I can not recall if the new structure is composed entirely of the dead ants or if dirt is involved as well.
