• Genus: Camponotus
• Family: Formicidae
• Subfamily: Formicinae
• Distribution: South America (mainly Andean regions and warm, humid areas).

Morphology

• Size:
  • Queen: 12–15 mm
  • Minor workers: 4–7 mm

• Coloration: Dark shades from brown to black, moderately shiny.
• Distinctive traits: Robust body typical of Camponotus, broad heads in major workers, strong mandibles, and long antennae.

Behavior

• Type: Semi-nesting species; prefers decayed wood, cracks, or narrow spaces.
• Activity: Active in the late afternoon and night (crepuscular/nocturnal).
• Foraging: Slow but steady; workers explore individually.

Diet

• Feed on sugary liquids (sugar water, honey, artificial nectar) and proteins (small insects, chopped crickets, flies, etc.).
• Prefer soft and sweet foods.

Humidity and Temperature

• Ideal temperature: 22–26 °C
• Nest humidity: 50–70%
• Foraging area humidity: 40–60%
• Hibernation/diapause: Not strictly required; a slight drop to 18–20 °C in winter is beneficial.

Maintenance Level

• Level: Easy – Intermediate
• Colonies are manageable but grow slowly; prefer stable humidity.
• Require spacious nests for major workers.

Colony Growth

• Maximum colony size: 1,000–3,000 individuals
• Time to first workers: 6–8 weeks from egg laying

Recommended Nest Type

• Acrylic or plaster nests with controlled humidity.
• Alternative: Treated wood to simulate natural habitat.
• Wide passages to accommodate major workers.
• Spacious and ventilated foraging area.
