Camponotus bispinosus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Tropical forests of Central and South America, from Honduras through Colombia (Guajira, Magdalena, Cundinamarca, Valle del Cauca, Tolima, Meta, Huila) to Brazil ^[2][3]. Found in trees in tropical forests and often collected in pitfall traps ^[2].
• Colony Type: Likely single-queen colonies based on typical Camponotus patterns. Forms large colonies in the canopy with extensive foraging trail systems ^[4].
• Size & Growth:
  • Queen: Size data unavailable, inferred from typical Camponotus queen size (~9-12mm)
  • Worker: 3.3mm ^[1]
  • Colony: Large colonies, exact maximum unknown but forms extensive foraging trails covering ~10m² ^[4]
  • Growth: Moderate
  • Development: Development timeline unconfirmed for this species. Based on typical Camponotus patterns, expect first workers in 4-8 weeks at tropical temperatures. (Development may be faster than temperate Camponotus due to tropical origin.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. These are tropical ants requiring warm, stable temperatures year-round. A heating cable on one side of the nest creates a suitable gradient.
  • Humidity: High humidity required, these ants show strong positive correlation with air humidity in the wild, with abundance ten times higher during humid periods ^[5][6]. Keep nest substrate consistently moist but not waterlogged. Provide a water tube for drinking access.
  • Diapause: No, these are tropical ants that do not hibernate. Maintain warm conditions year-round ^[4].
  • Nesting: Arboreal nesting preferences. In captivity, they do well in Y-tong (AAC) nests or plaster nests that retain humidity. Provide vertical space and climbing structures since they naturally nest in trees ^[2]. A naturalistic setup with cork bark or branches works well.
• Behavior: Nocturnal foragers, they leave the nest at night to search for food ^[4]. Workers are not particularly aggressive but will defend their colony if threatened. They form well-organized foraging trails that persist over time. Escape risk is moderate, use standard Camponotus escape prevention (fluon on edges). Small size means they can squeeze through small gaps, so ensure tight-fitting lids. They are generalist foragers typical of the genus.
• Common Issues: fungal infection risk is high, these ants are naturally parasitized by Ophiocordyceps fungus, keep enclosures clean and dry to prevent mold and fungal growth, humidity management is critical, too dry and colonies struggle, too wet and mold becomes a problem, nocturnal activity means you'll see most movement in evening hours, don't assume they're inactive during the day, large colony size requires significant space, plan for expansion as colonies grow, tropical species cannot tolerate cool temperatures, keep away from air conditioning and cold drafts

Housing and Nest Setup

Camponotus bispinosus does well in Y-tong (AAC) nests or plaster formicaria that hold humidity well. Since they're an arboreal species naturally found in trees, provide some vertical climbing space and structures like cork bark or fake plants ^[2]. These ants are nocturnal, so their activity peaks in evening and night hours, place their enclosure where you can observe them during these times. A test tube setup works for founding colonies, but be prepared to move them to a larger setup once the colony reaches 15-20 workers. The key is maintaining humidity while avoiding stagnant air, use adequate ventilation with small holes or mesh that allows airflow without drying the nest too quickly.

Feeding and Diet

Like most Camponotus species, these ants are generalist foragers. They accept sugar sources (honey water, sugar water) and protein foods (mealworms, crickets, other small insects). In the wild, they forage extensively at night across their trail networks ^[4]. Feed them a few drops of sugar water twice weekly and offer protein (small insects) 2-3 times per week. Remove uneaten protein after 24-48 hours to prevent mold. Since they form large colonies, food requirements increase significantly as the colony grows. Always ensure fresh water is available.

Temperature and Humidity

These are tropical ants requiring temperatures between 24-28°C year-round. They do not tolerate cool conditions and lack any diapause requirement, maintain warm temperatures consistently. Humidity is particularly important: research shows their abundance in the wild is ten times higher during humid periods compared to dry periods ^[5][6]. Keep the nest substrate consistently moist but not waterlogged. A water tube attached to the nest provides drinking access. Avoid placing the enclosure near air conditioning or cold drafts. A small digital thermometer/hygrometer helps monitor conditions.

Colony Development

Colony founding behavior is unconfirmed for this species. Based on typical Camponotus patterns, the queen likely seals herself in a chamber and raises her first workers on stored body fat reserves. Expect the first workers to emerge in 4-8 weeks under warm conditions (25-28°C). Colonies grow moderately, not as fast as some tropical species but faster than temperate Camponotus. The key challenge is the transition from founding colony to established colony, as the fungus that attacks them in the wild can also affect captive colonies if conditions become too humid or moldy. Once established with 50+ workers, colonies grow more steadily.

The Zombie Fungus Relationship

This species has a well-documented relationship with the specialized parasitic fungus Ophiocordyceps camponoti-bispinosi. Infected ants leave their colonies at night (their normal foraging time) and climb up to bite onto palm tree thorns ^[5][6]. The fungus then kills the ant and grows a stalk from its head to release spores. In some wild populations, nearly 18% of ants are infected ^[5][6]. For antkeepers, this means: keep enclosures clean and dry, remove any dead ants promptly, and avoid introducing materials from tropical forests that might carry the fungus. This is one of the few ant species where disease prevention is a genuine daily concern.

Behavior and Activity Patterns

These ants are strictly nocturnal, workers emerge at night to forage along established trails that can cover approximately 10 square meters and persist for long periods ^[4]. They form large colonies in the canopy of tropical trees. Workers are not particularly aggressive toward keepers but will defend the nest if disturbed. Their small size (3.3mm) means they can escape through very small gaps, use fluon on enclosure edges and ensure lids fit tightly ^[1]. The extensive foraging trail behavior suggests they need more space than typical ground-nesting Camponotus as colonies grow. They're generalists that will explore and exploit various food sources.
