Elongate twig ant

The elongate twig ant, Pseudomyrmex gracilis, is a large, slender species native to Mexico. The workers are about 8–10 millimeters (0.31–0.39 in) in length and generally wasp-like in appearance and style of movement. Worker ants are bi-colored; the head and gaster are dark, while the antennae, mouthparts, thorax and legs are dull orange with dark shading. There is one queen per colony. The nests, which are small and contain few ants, are often constructed high up in trees. The ants can sting painfully and they defend their nests vigorously. They often may be seen on vegetation, foraging for live insects or collecting honeydew from sap-sucking insects.-Wikipedia
