Camponotus barbaricus – Mediterranean giant ant

Camponotus barbaricus is one of the largest and most impressive ant species from Southern Europe. This species is prized for its large size, beautiful red-black coloration, calm temperament, and distinct polymorphism. As the colony grows, alongside smaller workers, large majors emerge with a strikingly broad head and powerful mandibles.

In the wild, Camponotus barbaricus occurs in Spain and Portugal, where colonies live in warm, dry areas. They nest primarily in the soil under stones, between tree roots, or in dry, sandy soil. Worker ants are mainly active during the warmer hours of the day and collect sugary fluids and insects for the colony.

The colony grows slowly during the first few years, as is characteristic of many Camponotus species. As the colony expands, the growth rate increases and the first impressive majors appear. Due to their calm behavior, large size, and beautiful appearance, Camponotus barbaricus is one of the most popular giant ants among ant keepers.

Power supply

Camponotus barbaricus is an omnivorous ant species that requires both proteins and sugars for the healthy development of the colony.

Diet: insects such as redrunners, crickets, mealworms, buffalo worms, dubia cockroaches, and fruit flies.

Sugars: Byformica Sunburst Ant Nectar, sugar water, honey water and beetle jelly.

During the growth of the colony, a varied supply of protein-rich insects is important for the healthy development of the brood.

Care

Camponotus barbaricus prefers a dry to slightly damp nest with a small damp zone for the brood. The species benefits from a warm environment and develops fastest at temperatures between 25 and 28°C.

Due to their large size, the ants are easy to observe. They are generally calm, but majors can use their powerful jaws when the colony feels threatened.

From how many workers to a nest: +- 20 – 30 workers

Recommended nest type:

3D nest, Ytong nest, acrylic nest, plaster nest

An arena with sand or sand/loam creates a natural appearance and stimulates natural foraging behavior.
