Camponotus gundlachi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Cuba and the Greater Antilles in the Neotropical region. This species is endemic to Cuba, found nowhere else on Earth ^[1]. In the wild, they likely nest in rotting wood, under bark, or in hollow stems, typical habitat for Camponotus species in tropical forest environments.
• Colony Type: Likely single-queen colonies (monogyne), based on typical Camponotus patterns. The colony structure follows the standard carpenter ant pattern with one reproductive queen and worker castes.
• Size & Growth:
  • Queen: Estimated 10-12mm, inferred from typical Camponotus queen size (direct measurements not available for this species)
  • Worker: 5-8mm, inferred from type description and related species ^[2]
  • Colony: Likely reaches several hundred to a few thousand workers at maturity, based on typical Camponotus patterns
  • Growth: Moderate, Camponotus species typically grow at a moderate pace, faster in warm conditions
  • Development: Estimated 6-8 weeks at optimal temperature (25-27°C), based on typical Camponotus development patterns (Development time is temperature-dependent, warmer conditions accelerate development while cooler temperatures slow it down)
• Antkeeping:
  • Temperature: Keep nest area at 24-27°C. Provide a temperature gradient so ants can self-regulate. This is a tropical species from Cuba, so it prefers warm conditions year-round ^[2].
  • Humidity: Moderate to high humidity. Keep nest substrate slightly moist but not waterlogged. Provide a water tube for drinking access. Tropical ants generally benefit from humidity levels that prevent excessive drying.
  • Diapause: No true diapause required. As a tropical species from Cuba, they do not experience cold winters that would trigger hibernation. Keep them at stable warm temperatures year-round.
  • Nesting: Y-tong (AAC) nests work well for this species. They prefer nests with narrow chambers and tight passages that allow them to use their head-plugging behavior. Wooden formicaria or plaster nests with appropriate humidity control are also suitable. Avoid very large open spaces, they prefer cozy, snug chambers.
• Behavior: This is a generally calm, non-aggressive species. Workers are not particularly territorial and typically focus on foraging for honeydew and small insects. They are not known for stinging, their primary defense is the head-plugging behavior mentioned above. Escape risk is moderate, use standard barriers but they are not particularly adept escape artists compared to some tiny species. They are primarily nocturnal or crepuscular foragers, so expect most activity during evening and night hours.
• Common Issues: queen loss during founding is common, ensure founding chamber is secure and undisturbed, humidity control is important, too dry and brood desiccates, too wet and mold becomes a problem, slow initial colony growth can lead to overfeeding, only offer what they can consume, tropical species are temperature-sensitive, avoid cold drafts and sudden temperature drops, head-plugging behavior may make them appear inactive during day, this is normal, not a problem

Housing and Nest Setup

Camponotus gundlachi does well in Y-tong (AAC) nests or wooden formicaria. The key is providing appropriately sized chambers, not too large, as these ants prefer snug spaces where they can properly utilize their head-plugging defensive behavior. A test tube setup works well for founding colonies, once the colony reaches 15-20 workers, you can consider moving them to a proper formicarium. Ensure the nest has a water reservoir (test tube with cotton) for humidity control. For the outworld, a simple foraging area with a sugar water feeder and protein food dish is sufficient. Use a barrier like fluon around the rim to prevent escapes. ^[2]

Feeding and Diet

Like most Camponotus, this species is omnivorous with a preference for sugar sources. Offer sugar water, honey, or diluted maple syrup as a constant energy source. For protein, provide small insects like fruit flies, small mealworms, or cricket pieces. They will also collect honeydew from aphids if available. Feed protein 2-3 times per week, removing any uneaten prey after 24 hours. Sugar water should always be available. Fresh water should be accessible at all times. ^[2]

Temperature and Seasonal Care

As a tropical species from Cuba, Camponotus gundlachi requires warm conditions year-round. Keep the nest area at 24-27°C (75-80°F). A small heating cable on one side of the nest can create a beneficial temperature gradient. Room temperature (around 22-24°C) is acceptable but on the cooler end of their preference. Avoid temperatures below 20°C as this can slow colony development significantly. No hibernation or diapause is required, maintain consistent warm conditions throughout the year. ^[2]

Behavior and Observation

The most fascinating aspect of keeping this species is observing their unique defensive behavior. Workers will position themselves at nest entrances with their modified head facing outward, essentially plugging the hole like a cork. This is why they're called cork-headed ants. They are generally docile and won't bite aggressively. Most foraging activity occurs during evening and nighttime hours, so do not be concerned if your colony seems quiet during the day. They are not particularly aggressive toward each other and colony harmony is typically good. Watch for dealate queens (ones that have shed their wings) if you have a founding colony, this indicates the queen has successfully mated and is entering the claustral founding phase. ^[2]

Colony Development and Growth

A newly mated queen will seal herself into a founding chamber and lay her first batch of eggs. She will not leave to forage during this time, she survives entirely on stored fat reserves (claustral founding). The first workers, called nanitics, are typically smaller than mature workers and help the colony expand. After nanitics emerge, the queen can stop tending to brood directly and focus on egg-laying while workers take over all colony tasks. Growth is moderate, expect 6-8 weeks from egg to first worker at optimal temperature. Colonies can take several months to reach 30-50 workers and a year or more to reach several hundred. ^[2]
