Pseudomyrmex pallidus
Pallidus-group Twig Ants
Pseudomyrmex pallidus is a small, slender ant species native to the Nearctic and Neotropical realms, with an extensive range from the southern United States through Central America and into South America. Workers are monomorphic and exhibit variable coloration from yellow to orange or brown. The species nests exclusively in hollow stems of dead grasses and woody twigs, typically at the interface of grassy and wooded habitats. Colonies are facultatively polygynous and polydomous, containing 1–15 queens and 20–200 workers.
