Linepithema humile, the Argentine ant, queen and worker in the species' native range. Córdoba, Argentina
Ground pearls are the large, sedentary adult forms of root-sap feeding insects. Here, two Eurhizococcus brasiliensis hang suspended from grape roots deep underground while a Linepithema micans ant gathers the honeydew exuded by the pearls. These insects are significant pests in Brazilian vineyards. Bento Gonçalves, Rio Grande do Sul, Brazil

Workers tend to a queen in a laboratory colony of Argentine Ants (Linepithema humile). California, USA
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. Davis, California, USA
A feisty little Argentine ant (Linepithema humile) attacks a much larger fire ant (Solenopsis invicta). Both species co-exist naturally in subtropical South America, but in the southern United States where both have been accidentally introduced, the fire ant has displaced the Argentine ants. Austin, Texas, USA
