is an inconspicuous but ecologically important ant of Neotropical forests and mountains. One species, the Argentine ant L. humile, has become a significant pest in mediterranean climates worldwide.
As a colony of subterranean termites (Reticulitermes hesperus) prepares for the annual release of winged reproductives, a predatory Argentine ant (Linepithema humile) approaches the nest for an easy protein meal.
