Forelius ants (Forelius pruinosus) are tiny, pale yellow to light brown ants that are extremely common in Arizona's desert and urban environments. They are among the most heat-tolerant ants in the Sonoran Desert, remaining active on hot pavement and open ground when other ants retreat underground. Workers are fast-moving and form dense, well-defined trails to food sources. They are omnivores, feeding on sweets, dead insects, and plant secretions. Forelius ants nest in soil, under rocks, and along sidewalk edges. They are primarily an outdoor nuisance but can invade homes in large numbers during extreme heat or monsoon rains.
