Liometopum is a genus of ants that belongs to the subfamily Dolichoderinae, found in North America, Europe and Asia. Caterpillars of certain butterfly species have a symbiotic relationship with Liometopum ants. They produce secretions that the ants will feed on, similar to the Iridomyrmex genus of ants.
