Eciton burchellii soldier, Leticia, Colombia
During a night tour in Leticia we were lucky to come across this army ant raid taking place on a fallen tree crossing our path. This particular photo is of the soldier class with their oversized heads. They are absolutely fearless in defending the colony. This individual was leaning in to me instead of trying to escape me.

"Eciton burchellii" is a species of New World army ant in the genus "Eciton". This species performs expansive, organized swarm raids that give it the informal name, "Eciton" army ant. This species displays a high degree of worker polymorphism. Sterile workers are of four discrete size-castes: minors, medias, porters, and soldiers.
