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.
