Odontomachus brunneus


Ants of the genus Odontomachus are commonly called trap-jaw ants, due to the large, straight mandibles, which can be opened to 180 degrees and snapped shut on prey. They tend to be pretty timid for the most part, only accepting prey it can 100% take down, while other ants such as Solenopsis will attack anything that moves. When sensory hairs on the inside of the mandibles are touched, the trap jaw is triggered. The mandibles also permit slow and fine movements for other tasks such as nest building and care of larvae. Odontomachus brunneus ants have a particular seasonal breeding cycle, where offspring are produced during the first six months of the year and none are created in the later six months. Foraging is often slow during the breeding period due to the amount of Odontomachus brunneus ants reproducing, but is doubled by the time the breeding period comes to an end.
