Trachymyrmex saussurei

Distribution based on Regional Taxon Lists
Neotropical Region: Belize, Costa Rica, Guatemala, Honduras, Mexico.

Biology
In Tamaulipas, Mexico, was observed raiding a colony of Trachymyrmex saussurei (Rabeling & Sanchez-Peña, unpublished data). In the mountains of southern Arizona, two army ant species, Neivamyrmex nigrescens and Neivamyrmex rugulosus, prey on Trachymyrmex arizonensis (Miranda et al. 1980, LaPolla et al. 2002). Based on these few observations, army ants seem to be important predators of at least some Trachymyrmex species, and their raids may result in a significant brood loss and partial destruction of the fungus garden (LaPolla et al. 2002).
