About Pseudomyrmex gracilis (Fabricius, 1804)
Pseudomyrmex gracilis, commonly called the graceful twig ant, Mexican twig ant, slender twig ant, or elongated twig ant, is a large, slender ant species native to Mexico and arid regions of the United States. Worker individuals of this species measure around 8 to 10 millimeters (0.31 to 0.39 inches) in length, and have an overall appearance and movement pattern that resemble a wasp. Worker ants have two distinct color sections: their head and gaster are dark, while their antennae, mouthparts, thorax, and legs are dull orange with dark shading. These ants are often spotted on vegetation, where they forage for live insects and collect honeydew produced by sap-sucking insects. If a colony loses its queen, worker ants establish dominance hierarchies by boxing with their antennae. This process results in a small number of high-ranking workers that can lay eggs until a new queen joins the colony.
