在巴拿马大西洋沿岸的红树林中，树栖蚂蚁 Zacryptocerus maculatus 与阿兹特克属的领地蚂蚁呈正相关。系统抽样表明，这种关联并不是由于对相同大小或物种的树木的共同偏好造成的。此外，Z. maculatus 并没有因为被排除在其他丰富蚂蚁的领地之外而被迫生活在阿兹特克领地内。相反，这种关联似乎是由阿兹特克和斑斑斑鳅菌落之间的直接相互作用引起的。当 A. trigona 存在时，Z. maculatus 群体会进行一种不寻常的社会寄生形式。工人们沿着三角蝾螈侦察兵留下的信息素踪迹寻找新发现的食物来源。实际上，Z. maculatus 通过读取 A. trigona 的招募信号中包含的信息来寄生于 A. trigona 的觅食工作。 Z. maculatus 工蚁之所以能够获得这些资源，是因为它们的隐秘行动和不寻常的防弹衣。对相关蚂蚁的观察表明，这种寄生习性是 Harnedia 亚属内的其他 Zacryptocerus 物种所共有的。
In mangrove forests on the Atlantic coast of Panama, the arboreal ant Zacryptocerus maculatus was positively associated with territorial ants in the genus Azteca. Systematic sampling showed that this association was not caused by shared preference for the same size or species of tree. Furthermore, Z. maculatus was not forced to live within territories of Azteca by being excluded from the territories of other abundant ants. Instead, the association appeared to be caused by direct interactions between colonies of Azteca and Z. maculatus. When in the presence of A. trigona, colonies of Z. maculatus engaged in an unusual form of social parasitism. Workers followed pheromone trails deposited by scouts of A. trigona in order to locate newly discovered food sources. In effect, Z. maculatus parasitizes the foraging efforts of A. trigona by reading information contained within its recruitment signals. Z. maculatus workers were able to gain access to these resources because of their stealthy approach and unusual body armor. Observations on related ants suggest that this parasitic habit is shared by other species of Zacryptocerus within the subgenus Harnedia.
