• Odontomachus

  trap-jaw ants

  Odontomachus is a genus of ants commonly known as trap-jaw ants, characterized by their extraordinary spring-loaded mandibles that can snap shut at speeds among the fastest recorded for animal movements. The genus contains approximately 84 valid species distributed throughout tropical and subtropical regions worldwide. These ants are active predators that use their powerful jaws for hunting, defense, and in some species, locomotion via jumping. Several species have been introduced to new regions, including the southeastern United States, where they are expanding their ranges.

• Odontomachus brunneus

  Florida Trap-jaw Ant, Brown Trap-jaw Ant

  Odontomachus brunneus is a trap-jaw ant species notable for possessing the fastest predatory appendages recorded in the animal kingdom, with mandible closure speeds reaching 126-230 km/h. Workers exhibit cooperative rescue behavior toward trapped nestmates and maintain humid nest chambers that occasionally provide refugia for other species such as green anole eggs. The species has a distinctive seasonal breeding cycle with reproduction concentrated in the first six months of the year.
