Camponotus gambeyi

Camponotus gambeyi

Camponotus gambeyi is a medium-sized carpenter ant native to New Caledonia, a French territory in the South Pacific. Workers measure approximately 5-12mm depending on caste, with the typical dark coloration common to many Camponotus species. The species was originally described by Emery in 1883 and belongs to the subgenus Tanaemyrmex. This ant is endemic to New Caledonia, meaning it's found nowhere else on Earth naturally. The species inhabits dense humid forests on ultrabasic rock formations, making it a specialized species adapted to unique geological conditions found only on this island. A subspecies, Camponotus gambeyi marthae, is also recognized.

Quick Summary

• Difficulty: Medium
• Origin & Habitat: New Caledonia, a tropical island in the South Pacific. Found in dense humid forest on ultrabasic rocks ^[1]. This is a native species, not invasive.
• Colony Type: Likely single-queen colonies (monogyne), typical of most Camponotus species. Colony structure has not been directly studied for this specific species.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 12-16mm based on typical Camponotus genus patterns, not directly measured for this species
  • Worker: Estimated 5-12mm (polymorphic with major and minor workers)
  • Colony: Unknown for this species, likely several hundred workers based on genus patterns
  • Growth: Moderate, typical for tropical Camponotus
  • Development: Estimated 6-8 weeks at tropical temperatures (24-28°C), based on typical Camponotus development (Development time is estimated from related species, specific data for C. gambeyi is not available)
• Antkeeping:
  • Temperature: Keep at 24-28°C. Being from tropical New Caledonia, they need warm conditions year-round. A heating cable on one side of the nest creates a suitable gradient.
  • Humidity: High humidity required, they naturally live in humid forest environments. Keep nest substrate consistently moist but not waterlogged. The forest floor conditions they prefer mean damp substrate is essential.
  • Diapause: No, being from a tropical island, they do not require hibernation. Keep temperatures stable year-round.
  • Nesting: In nature, they likely nest in rotting wood or under stones in forest habitats. In captivity, a Y-tong (AAC) nest or plaster nest works well. They prefer tight, dark chambers. Avoid dry conditions.
• Behavior: Generally calm temperament typical of carpenter ants. They are not particularly aggressive but will defend their nest if threatened. Workers are moderately active foragers. Escape prevention should be moderate, they are not tiny ants but can squeeze through small gaps. They primarily forage for honeydew and small insects.
• Common Issues: high humidity maintenance is critical, dry conditions will stress and kill colonies, tropical species cannot tolerate cool temperatures, keep above 24°C, limited availability as a species, may be difficult to find in the antkeeping trade, slow colony growth compared to faster-growing tropical ants may frustrate beginners, wild-caught colonies may carry parasites specific to their native range

Natural History and Distribution

Camponotus gambeyi is endemic to New Caledonia, a unique tropical island in the South Pacific known for its distinctive flora and fauna. The species was first described by Carlo Emery in 1883 and has been recorded from various locations across the main island. It belongs to the subgenus Tanaemyrmex, a group of carpenter ants known for their moderate size and typical colony structures. The species is found specifically in dense humid forests growing on ultrabasic rocks, a geological formation common in New Caledonia that creates unique soil conditions. This habitat specialization suggests the species prefers stable, humid microclimates with plenty of cover and organic material. ^[1]

Nest Preferences and Housing

In their natural habitat, C. gambeyi likely nests in rotting wood or under stones in the humid forest floor, similar to other Camponotus species. For captive care, a Y-tong (AAC) nest or plaster formicarium works well. They prefer tight, dark chambers that mimic the inside of a rotting log or underground cavity. The nest should have a water reservoir to maintain humidity, these ants are sensitive to drying out. Keep the outworld simple with a foraging area and provide a hydration station. Because they come from a humid forest environment, the entire setup should maintain moisture without becoming stagnant.

Feeding and Diet

Like most Camponotus species, C. gambeyi is omnivorous with a preference for sugary substances and protein. In captivity, offer sugar water or honey regularly as a constant energy source. For protein, provide insects such as mealworms, crickets, or other small arthropods. They likely tend aphids in nature for honeydew, so offering sugar water is a good substitute. Feed protein prey 2-3 times per week, and keep sugar available at all times. Remove uneaten prey after 24 hours to prevent mold issues in the humid setup they require.

Temperature and Humidity Requirements

Being from tropical New Caledonia, these ants require warm and humid conditions year-round. Maintain temperatures between 24-28°C (75-82°F) in the nest area. A heating cable placed on top of the nest can help maintain stable temperatures, especially in cooler rooms. Humidity should be kept high, the forest floor environment they inhabit is consistently moist. Keep the nest substrate damp but not waterlogged, and provide a water gradient so workers can choose their preferred moisture level. Avoid placing the colony in air-conditioned rooms or anywhere temperatures might drop below 22°C. ^[1]

Colony Development

Queen founding behavior follows typical Camponotus patterns, the queen seals herself in a chamber and raises the first brood alone using stored fat reserves (claustral founding). The first workers, called nanitics, are typically smaller than mature workers and emerge after approximately 6-8 weeks at optimal temperatures. After the first workers eclose, the colony enters a growth phase. Development is likely slower than temperate species due to the stable tropical conditions they evolved in. Expect moderate growth rates, a well-established colony may reach several hundred workers over 1-2 years with good care.

Behavior and Temperament

Camponotus gambeyi has a temperament typical of carpenter ants, generally calm and not overly aggressive. Workers will forage actively in the outworld and are capable of carrying relatively large prey items compared to their body size. They are not known for stinging and pose no danger to keepers. The species is moderately active and workers will establish clear foraging trails when food is available. Escape risk is moderate, while not tiny, they can squeeze through small gaps, so standard escape prevention measures are sufficient. They do not exhibit unusual behaviors like slave-making or temporary parasitism.
