Nomamyrmex esenbeckii & Atta colombica

photograph © Alex Wild 2007

Nomamyrmex army ants are among the few animals that successfully attack leaf-cutter ant nests. The leaf-cutters are not without their defenses, however.  Here two Atta workers kill a Nomamyrmex esenbeckii scout that has crossed their path, preventing the army ant colony from discovering the leaf-cutter's trail.
