Pseudomyrmex gracilis, also known as the graceful twig ant, Mexican twig ant, slender twig ant, or elongated twig ant, is a large, slender species of ant native to Mexico and arid parts of the US. 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. They often may be seen on vegetation, foraging for live insects or collecting honeydew from sap-sucking insects.
If the colony ever finds themselves without a queen, the worker ants form dominance hierarchies by boxing with their antennae. This leads to a couple high ranking individuals which can lay eggs until a new queen returns. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Graceful Twig Ant is recorded against all the insects logged in San Antonio (30 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
