Summary
Odontomachus is a genus of ants known as trap-jaw ants, characterized by their unique mandibles that can open 180º and snap shut at high speeds. They are found in tropical and subtropical regions around the world and display carnivorous behavior.
Physical Characteristics
Trap-jaw ants possess large, straight mandibles capable of opening 180º, which are equipped with a hair-trigger mechanism for rapid closure.
Identification Tips
Identification can be made by observing their unique mandibles, which are held open at 180 degrees and snap shut quickly.
Habitat
Odontomachus species are found in tropical and subtropical regions worldwide, favoring diverse habitats such as forests and grasslands.
Distribution
Species of Odontomachus are distributed across Central and South America, Asia, Australia, and Africa. In the United States, they have been recorded in Alabama and Florida.
Diet
Odontomachus ants are primarily carnivorous but also consume nectar, insect honeydew, and ripe fruit.
Life Cycle
The larvae are carnivorous and undergo three moults before metamorphosis, spinning cocoons from substrate. They have long spikes and dorsal adhesive pads to cling to the nest walls.
Ecosystem Role
Trap-jaw ants play a significant role as predators in their ecosystems. They help control populations of other insects and contribute to nutrient cycling.
Misconceptions
While they are known for their powerful jaws, their primary function is predatory, not for defense as commonly misunderstood.
