The tropical carpenter ant (Camponotus atriceps) is a large, robust ant species native to tropical regions of Central and South America. It is easily recognized by its glossy body, long legs, and strong mandibles, with workers varying in size due to the species’ pronounced caste polymorphism. Unlike termites, these ants do not eat wood but excavate galleries in dead or decaying wood, tree cavities, and sometimes wooden structures to build their nests. Camponotus atriceps is primarily nocturnal, foraging at night for a wide range of foods including insects, nectar, and honeydew from sap-feeding insects.



Diet

  • Omnivorous, feeding on honeydew from aphids, scale insects, and treehoppers, as well as nectar, plant sap, fruits, fungi, dead insects, and other arthropods.

  • Workers actively hunt or scavenge insects to provide protein for developing larvae.

  • Frequently visit flowers and extrafloral nectaries for sugary foods.

Range

  • Native to Mexico, Central America, the Caribbean, and much of northern and central South America, extending south to Brazil.

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

  • Occurs primarily in tropical and subtropical lowland habitats.

Habitat

  • Inhabits tropical dry forests, tropical rainforests, mangrove forests, secondary forests, woodland edges, plantations, gardens, and urban areas.

  • Nests in dead trees, rotting logs, hollow branches, beneath bark, wooden fence posts, and occasionally in buildings.

  • Forages both on the ground and in the forest canopy, often travelling long distances along well-defined trails.

Size

  • Worker length: 5–12 mm (0.2–0.5 in)

  • Major worker: Up to 14 mm (0.55 in)

  • Queen length: 15–18 mm (0.6–0.7 in)

  • Colonies typically contain several thousand workers.
