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.
