Camponotus ocreatus is a striking desert carpenter ant native to the southwestern United States and northern Mexico. This beautiful species is instantly recognisable by its contrasting black head and amber-orange body, making it one of the most visually distinctive members of the Camponotus genus.
Rarely available in Europe, and even less commonly offered in the UK, C. ocreatus is highly sought after by collectors due to its unique appearance, impressive size, and fascinating colony structure. Their elegant colouration, active foraging behaviour, and large workers make them a true centrepiece species for any ant keeper.
Care Requirements
Colony Structure
Facultatively polygyne (multiple queens may coexist under suitable conditions)
Fully claustral founding species
Colonies can exceed 10,000 workers per queen in mature nests
Queens generally found independently but may accept supplementary feeding during founding
Moderate growth rate compared to many other Camponotus species
Temperature
Ideal: 26-28°C 
Consistent heating significantly improves brood development and colony growth
Humidity
Nest humidity: 60–75%
Outworld humidity: Low to moderate
Provide a humidity gradient, allowing the colony to choose preferred conditions
Avoid excessive moisture, as this is a desert-adapted species
Diapause
Recommended winter diapause of 2–3 months
Temperature: 12–15°C
Typically, from November through January
Colonies should remain hydrated during diapause but require very little food
Polymorphism
Moderately polymorphic species
Workers display noticeable size variation
No true major or soldier caste, although larger workers develop significantly broader heads and stronger mandibles
Diet
Carbohydrates
Sugar water
Honey water
Maple syrup (occasionally)
Commercial ant nectar
Protein
Roaches
Crickets
Locusts
Mealworms
Fruit flies
Other feeder insects
Protein requirements increase substantially when brood is present.
Suitable Nest Types
For founding colonies:
X Series Combo Starter Nest
Vertex Combo Nest
For established colonies:
Medium to large acrylic or hybrid nests
Modular nest systems that allow gradual expansion
Dry nests with a hydrated section work particularly well
Size
Queen: 14–17.5 mm
Workers: 6.5–13 mm
Difficulty Level
Intermediate
While relatively forgiving once established, Camponotus ocreatus requires stable heating, a proper diapause period, and patience during founding. The species rewards keepers with beautiful colouration, impressive worker size variation, and highly active foraging behaviour.
