The term "Ant Tree" refers to several South American tree species within the genus Triplaris, renowned for their hollow stems frequently inhabited by venomous ants. Among these, Triplaris americana, commonly known as Pau-de-formiga or Guacamayo, is the most prevalent. Triplaris americana is indigenous to Central and South America, spanning from Panama to Brazil. It establishes a symbiotic relationship with stinging ant species, primarily Azteca spp., which inhabit the hollow stems of the tree, offering protection against herbivores and some defense against predators.

Triplaris americana does not hold any known nutritional value for human consumption. It is not utilized as a food source and primarily serves ecological purposes within its native habitat.
The distinctive feature of Triplaris americana lies in its ecological properties, particularly the ant-tree relationship. The hollow stems of the tree provide ideal habitats for colonies of stinging ants, such as Azteca spp. Furthermore, the tree produces nectar-rich structures known as domatia, attracting and sustaining the resident ant populations. This mutualistic relationship serves as a natural defense mechanism against herbivores, as the stinging ants deter animals from consuming the tree's foliage.
There are no reported side effects associated with Triplaris americana itself. However, individuals should exercise caution when encountering the tree in its natural habitat, especially if inhabited by stinging ant colonies. Ant bites can cause painful reactions and allergic responses in susceptible individuals.
Triplaris americana is not commonly utilized for medicinal or commercial purposes. However, it serves as a compelling example of plant-animal symbiosis and is cultivated in botanical gardens to showcase its unique ecological relationship. While it lacks direct human utility, it plays a vital role in maintaining ecosystem balance and biodiversity in its native habitats.
As Triplaris americana may harbor ant colonies, individuals should avoid close contact with the trunk or branches to prevent ant bites. If an ant tree infestation is suspected on personal property, it is advisable to consult a professional pest control service for safe and effective removal methods.
