Camponotus radamae

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to Madagascar, found in eastern humid forests ranging from littoral regions to mountaintops. The species is arboreal and terrestrial, nesting in rotten logs, tree stumps, dead branches, twigs, and rot pockets above ground ^[1].
• Colony Type: Based on typical Camponotus patterns, likely single-queen colonies. Colony structure in the wild has not been specifically documented.
• Size & Growth:
  • Queen: size data unavailable, inferred from Camponotus genus (~12-16mm)
  • Worker: size data unavailable, minor workers are smaller than major workers based on typical Camponotus dimorphism ^[1]
  • Colony: estimated up to several thousand workers based on typical Camponotus colony development
  • Growth: moderate, Camponotus species typically grow at a moderate pace
  • Development: estimated 6-8 weeks at optimal temperature based on typical Camponotus development (Development time is inferred from genus-level data as species-specific measurements are not available. Nanitics (first workers) are typically smaller than normal workers.)
• Antkeeping:
  • Temperature: Keep at 22-26°C with a gentle gradient. As a tropical species from Madagascar, they prefer warm conditions but avoid excessive heat. Room temperature within this range works well, or use a heating cable on one side of the nest for temperature control ^[1].
  • Humidity: Moderate to high humidity (60-80%). These ants come from humid forest environments, so maintain moisture in the nest substrate. Provide a water tube for drinking access. Mist occasionally but ensure good ventilation to prevent mold.
  • Diapause: No, as a tropical species from Madagascar, they do not require hibernation. Maintain consistent temperatures year-round.
  • Nesting: Arboreal nester, provide nesting options that mimic their natural habitat. Rotten wood, cork bark, or a Y-tong (AAC) nest with wood-like materials work well. They prefer elevated nest sites and rarely forage on the ground. Avoid fully underground setups.
• Behavior: Workers are moderately active and primarily forage on vegetation and in the canopy, not on the ground. They are not particularly aggressive but will defend their nest. As a Formicinae ant, they lack a functional sting but can bite and spray formic acid from their acidopore if threatened. Escape risk is moderate due to their size, standard formicarium barriers are usually sufficient. They are primarily nocturnal or crepuscular foragers.
• Common Issues: tropical species may suffer if temperatures drop below 20°C, arboreal nesting means they need elevated nest sites, ground-based setups may not be accepted, colonies may be slow to establish during founding phase, poor ventilation can lead to mold problems in their humid environment, formic acid spray from acidopore can cause skin irritation, handle with care

Housing and Nest Preferences

Camponotus radamae is an arboreal species, meaning they prefer to nest above ground rather than in underground chambers. In captivity, they do well in Y-tong (AAC) nests, cork bark setups, or wooden formicaria that mimic their natural nesting in rotten logs and dead branches. The nest should have chambers scaled to their size, major workers need larger passages than minor workers. Place the nest in a warm, humid area of your setup. Since workers rarely forage on the ground, consider adding climbing structures like twigs or plants that reach up to the nest entrance. This helps simulate their natural canopy-edge foraging behavior. ^[1]

Feeding and Diet

Like most Camponotus species, C. radamae is omnivorous. They accept sugar sources (honey water, sugar water) and protein foods (insects, mealworms, crickets). In the wild, they forage for honeydew from aphids and scale insects on vegetation, plus small arthropods. Feed them a varied diet: offer protein 2-3 times per week and keep a constant sugar water supply. They are not aggressive hunters but will take small live prey. Remove uneaten food after 24-48 hours to prevent mold. ^[1]

Temperature and Seasonal Care

As a tropical species from Madagascar, C. radamae needs warm temperatures year-round. Keep the nest area at 22-26°C. They do not enter diapause or hibernation, so maintain consistent temperatures throughout the year. Avoid temperatures below 20°C, as this can stress the colony and slow development. A heating cable placed on one side of the nest creates a gentle temperature gradient that allows ants to regulate their own position. Room temperature in most homes is acceptable if it falls within their preferred range. ^[1]

Behavior and Colony Dynamics

This species has distinct worker castes, minor workers handle most foraging and brood care, while major workers defend the nest and may assist with processing larger food items. Workers are primarily nocturnal or crepuscular, foraging on vegetation and in the canopy rather than on the ground. They are not overly aggressive but will defend if threatened. As Formicinae ants, they lack a functional sting and instead use their bite combined with spraying formic acid from their acidopore as defense. The colony will grow over time as the queen produces more workers. Expect the first wave of workers (nanitics) to be smaller than subsequent generations. ^[1]
