Natural History
These are ants of open areas and synanthropic habitats that can be expected in any low to midelevation urban area in Costa Rica. I have found workers foraging on the ground in the town squares of La Cruz and Liberia in Guanacaste Province. I have collected workers while sweeping low vegetation along the dusty roadside near La Pita, on the road from the PanAmerican Highway to Monteverde. On the Atlantic side of Costa Rica, I collected workers on the beach margin beneath coconut palms near Puerto Viejo de Limon.
