Biology
Little is known about the biology of Patagonomyrmex other than observations made by Kusnezov (1949, 1953, 1960). Most of his observations were for Pa. odoratus, but the biology of these three species appears similar, and thus all three species are discussed together. Nests are variable, ranging from an entrance lacking a tumulus to one that is 10–12 cm in diameter. Typically, nests are located in open areas or under stones or other objects. Workers of all three species are diurnal, slow-moving, solitary foragers that are timid and non-aggressive. Little information is available on food items collected, though Kusnezov (1960) indicated that they were granivores. Colonies of Pa. odoratus probably contain fewer than 300–400 workers (Kusnezov, 1949); colony size for Pa. angustus and Pa. laevigatus appears to be similar (Kusnezov, 1949; 1960; pers. obs.).
