This species can be found in dry forest or wet forest, from sea level to montane areas.
Raiding is always in columns, never in a carpet like E. burchellii. Many of the raiding columns I have observed have been at night, showing a tendency to be nocturnal, but I also encounter columns during the day. The few times I have encountered prey they have been large ponerines in the genera Ectatomma and Pachycondyla.
