Odontomachus monticola, commonly known as the trap-jaw ant, is a fascinating species known for its lightning-fast mandibles and unique hunting techniques. These ants can snap their jaws shut at high speeds to capture prey, defend their colony, or even propel themselves backward to escape danger. They are native to Southeast Asia, thriving in tropical rainforests where they build their nests under stones and rotten wood.
This species is not recommended for beginners, as they require precise humidity, temperature, and escape-proof enclosures due to their high activity levels. If you are an experienced ant keeper looking for an exotic species, Odontomachus monticola is an excellent choice!
Odontomachus monticola
Odontomachus monticola is a polygynous species, meaning a colony can have multiple queens, which leads to larger and more stable colonies. Colonies can reach up to 300 workers, making them a medium-sized species in the Odontomachus genus.
