Nest cedar lumber. When digging the nests, they use the wood shavings scraped from the wall to create partitions within the tunnels. The nests are usually round and have about 1-4 tunnels, each with multiple branches. Because these materials are often useful for humans in construction, "X. virgininica's" nesting behavior presents the disadvantage of weakening wood in manmade structures. The abundance of biological resources within the nest has led to a number of specialized predators. The aardvark and the ant eater use long tongues to prey upon termite and ant nests. Birds such as the honey buzzard specialize on wasp and
Longhorn crazy ant research station Biosphere 2 in the Arizona Desert, no particular ant species was dominant. By 1996, the longhorn crazy ant had virtually replaced all the other ant species.
