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.
Black Leafcutter Ant
A cold-tolerant leafcutter ant that builds conspicuous mound nests from vegetation debris. Workers are dark brown to black with prominent thoracic spines. This species can survive in temperate climates unusual for leafcutters.
Did You Know?
They are the most cold-tolerant leafcutter ants, surviving in regions where winter temperatures drop below freezing.
