Dacetine Trap-Jaw Ant
A minute trap-jaw ant with elongate mandibles fringed with specialized hairs used to detect and capture tiny soil-dwelling springtails. Workers are slow-moving, cryptic hunters that stalk prey in leaf litter. Their bodies are covered in bizarre spatulate hairs.
Did You Know?
Their mandible trigger hairs are so sensitive they can detect the vibrations of a springtail walking nearby and snap shut in microseconds.
Fierce Big-Headed Ant
A widespread tropical ant and minor invasive species with clearly dimorphic workers. Majors have disproportionately large heads used in colony defense. Colonies are aggressive and fast-growing, often dominating disturbed tropical habitats.
Did You Know?
Despite being one of the most species-rich ant genera with over 1,000 species, Pheidole remains one of the least studied.
