Odontomachus haematodus, commonly known as the trap-jaw ant, is a species of ant in the subfamily Ponerinae. These ants are famous for their incredibly fast and powerful mandibles, which they use both for capturing prey and defending themselves. They are typically reddish-brown to dark brown. Odontomachus haematodus is a predatory ant, feeding on a variety of small arthropods. The trap-jaw mechanism helps them quickly subdue fast-moving or evasive prey.



Diet

  • Predatory, feeding primarily on ants, termites, flies, beetles, caterpillars, spiders, centipedes, and other small arthropods.

  • Also scavenges dead insects and occasionally feeds on nectar and honeydew.

  • Workers hunt alone, capturing prey with their powerful trap-like mandibles before delivering a venomous sting.

Range

  • Native to Mexico, Central America, the Caribbean, and much of northern South America.

  • Widespread in Mexico, including the Pacific coast of Guerrero and the Zihuatanejo region.

  • It has also become established as an introduced species in parts of the southeastern United States.

Habitat

  • Inhabits tropical dry forests, tropical rainforests, mangroves, secondary forests, woodland edges, plantations, gardens, and urban green spaces.

  • Nests in soil, beneath stones, under leaf litter, inside rotting logs, and beneath loose bark.

  • Most active on the forest floor, especially in warm, humid conditions.

Size

  • Worker length: 8–12 mm (0.3–0.5 in)

  • Queen length: 12–15 mm (0.5–0.6 in)

  • Colonies generally contain 100–1,000 workers.
