COMPLEX REPAIR. “The Macrotermes mound illustrates this argument in a compelling way. The aftermath of mound repair is the superorganismal equivalent of scar tissue: disordered and disorganized structure with compromised function. Behind the plug is the ragged and tortuous spaces where the spongy build merges into the broader spaces of the mound reticulum. There is also the residue of the many sites of aborted stigmergic building: pillars, walls, incomplete spongy build and partially blocked tunnels. Once mound repair is complete, these are gradually dismantled and the tunnels returned to their smooth condition prior to the injury, which also restores the mound to full functionality.”
