THE EXTERNAL MOUND. “Macrotermes colonies characteristically build prominent above-ground structures that can rise several meters above the nest. Although the mound-building habit is found among other termites, such as the dramatic blade-like “magnetic” mounds built by the Australian termite Amitermes meridionalis, these other mounds invariably serve as the colony’s residence . The Macrotermes colony, in contrast, does not inhabit its mound, but is situated in the subterranean nest.”
