Camponotus spinolae

Quick Summary

• Difficulty: Medium
• Origin & Habitat: South America, documented in Bolivia ^[1] and Chile ^[2]. The specific habitat within this range has not been studied.
• Colony Type: Unconfirmed, likely single-queen based on typical Camponotus patterns.
• Size & Growth:
  • Queen: Size data unavailable for this species, inferred from Camponotus genus (~15-18mm)
  • Worker: Size data unavailable for this species, inferred from Camponotus genus (~6-15mm, polymorphic majors and minors)
  • Colony: Likely reaches several thousand workers at maturity, inferred from Camponotus genus patterns
  • Growth: Moderate, Camponotus species grow more slowly than smaller ants
  • Development: Estimated 6-10 weeks at warm temperatures, inferred from Camponotus genus patterns (Development time is estimated from related species, this species has not been directly studied. Cooler temperatures will slow development significantly.)
• Antkeeping:
  • Temperature: Keep nest area at 20-26°C with a gentle gradient. Room temperature around 20-22°C is suitable, with slight warming beneficial for brood development.
  • Humidity: Moderate humidity around 50-60%. Carpenter ants prefer somewhat drier conditions compared to tropical species. Provide a water tube for drinking access.
  • Diapause: Likely requires a winter rest period given the Chile distribution. Reduce temperature to 10-15°C for 2-3 months during winter.
  • Nesting: Y-tong (AAC) nests work well for this species. The chambers should be appropriately scaled, carpenter ants need moderate spacing. Wood-nesting species often adapt well to AAC or plaster nests in captivity.
• Behavior: Generally non-aggressive toward keepers but will defend the nest if threatened. Workers are primarily nocturnal or crepuscular, foraging for honeydew, aphid secretions, and protein. Escape risk is moderate, use standard barrier methods. Major workers can deliver a mild sting if handled roughly, though Camponotus are not known for aggressive stinging.
• Common Issues: limited distribution data means care recommendations are largely inferred from genus patterns, adjust based on colony behavior, slow founding phase compared to smaller ant species, beginners may lose patience during claustral founding, winter dormancy requirements may be unclear for this species given the Chile/Bolivia distribution ambiguity, test tube setups work for founding but colonies will need appropriately sized formicarium as they grow

Origin and Distribution

Camponotus spinolae is a South American carpenter ant species documented in Bolivia ^[1] and Chile ^[2]. The exact range within these countries is not well-defined in the scientific literature. This species was originally described in the late 1800s, and modern research on its distribution and ecology is extremely limited. The Chile location suggests adaptation to temperate or subtropical conditions, while the Bolivia records indicate presence in warmer regions.

Nest Preferences and Housing

As a Camponotus species, C. spinolae likely nests in wood in the wild, either in dead trees, stumps, or wooden structures. This aligns with the common name carpenter ant for the genus. In captivity, Y-tong (AAC) nests work well for most Camponotus species. The chamber size should be appropriate for the colony size, not too large for founding colonies, but spacious enough for mature colonies to accommodate thousands of workers. Plaster nests can also work, providing some moisture retention. Test tube setups are suitable for founding colonies. Ensure adequate ventilation while maintaining stable humidity.

Feeding and Diet

Carpenter ants are omnivorous, feeding on honeydew from aphids and scale insects, nectar from flowers, and protein from insects. In captivity, offer sugar water or honey as a constant energy source. For protein, provide insects such as mealworms, crickets, or other appropriately sized prey. Feed protein 2-3 times per week, and keep a sugar source available at all times. Remove uneaten prey after 24-48 hours to prevent mold. Camponotus colonies can be slow to accept new foods during the founding phase, be patient and try different options.

Temperature and Seasonal Care

Maintain nest temperatures between 20-26°C. Room temperature around 20-22°C is typically suitable for Camponotus species, with slight warming up to 26°C potentially speeding brood development. Given the Chile distribution, a winter rest period is likely beneficial. Reduce temperatures to 10-15°C for 2-3 months during winter months, mimicking natural seasonal cycles. During this time, reduce feeding significantly. This diapause period helps maintain colony health and may trigger reproductive behavior in spring. Do not feed during deep hibernation.

Colony Development

As a likely claustral species, the queen will seal herself in a chamber and not leave during founding. She relies entirely on stored fat reserves and metabolic energy to survive and raise the first brood. This founding phase can take several months, be patient and do not disturb the founding chamber. First workers (nanitics) will be smaller than normal workers but will immediately begin caring for the colony. Growth is typically moderate, Camponotus colonies do not explode in numbers like some smaller species. A mature colony may take several years to develop and can eventually reach several thousand workers.
