Camponotus dalmasi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Northern South America, Colombia (Sierra Nevada de Santa Marta, Magdalena, Antioquia, San Andrés) and Venezuela. Found in dry areas with shrubs, forests, and urban areas ^[1][2].
• Colony Type: Colony structure in the wild has not been documented. Based on typical Camponotus patterns, likely single-queen colonies.
• Size & Growth:
  • Queen: Size data unavailable, no direct measurements exist in available literature.
  • Worker: 3.2-5mm total length ^[3]. Minor workers around 3.2mm, major workers up to 5mm.
  • Colony: Maximum colony size is unknown, not documented in available research.
  • Growth: Growth rate is unconfirmed.
  • Development: Development time is unconfirmed, no species-specific research exists. (Based on typical Camponotus patterns, development likely takes several months at warm tropical temperatures.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. This is a tropical species from Colombia and Venezuela, so they prefer warm conditions. A heating cable on one side of the nest creates a gradient allowing workers to self-regulate.
  • Humidity: Moderate humidity. Their natural habitat includes forested areas, so they benefit from some moisture. Keep the nest substrate slightly moist but not waterlogged.
  • Diapause: No, as a tropical species from northern South America, they do not require hibernation.
  • Nesting: In the wild, they have been found in termite nests alongside Crematogaster ants ^[3][4]. In captivity, a Y-tong (AAC) nest or plaster nest works well. Provide a dark, secure nesting area. Because workers are only 3-5mm, ensure chambers are appropriately scaled.
• Behavior: These ants are relatively docile for a Camponotus species, they are not particularly aggressive. Workers are active foragers, both on the ground and likely in vegetation given their subgenus tendencies. They are attracted to sweet baits in the wild ^[2], so sugar water or honey should be readily accepted. Escape prevention is important, their 3-5mm size means they can squeeze through small gaps. Use standard barrier methods like fluon on test tube rims.
• Common Issues: limited availability, this species is rarely available in the antkeeping hobby, escape risk, small worker size means they can slip through standard test tube barriers if not properly sealed, humidity control, being from forested habitats, colonies may struggle in dry environments, lack of species-specific care data, most care recommendations are inferred from genus patterns rather than direct observation

Nest Preferences and Housing

In their natural habitat across Colombia and Venezuela, Camponotus dalmasi has been found nesting in association with termite colonies, specifically documented sharing a nest with Crematogaster ants inside a termite nest structure ^[3][4]. This suggests they may prefer pre-existing cavities rather than excavating their own. In captivity, provide a nest with dark chambers that mimic these natural cavities. Y-tong (AAC) nests work well for this species, as do plaster nests. The chambers should be appropriately sized for their 3-5mm workers, tight-fitting spaces help them feel secure. Include a water reservoir for humidity, and ensure the nest can be kept at stable warm temperatures between 24-28°C.

Feeding and Diet

Field observations show these ants are readily attracted to sweet baits ^[2], confirming they have a sweet tooth typical of Camponotus species. In captivity, offer sugar water or honey as a constant energy source. For protein, provide typical ant prey items: mealworms, small crickets, or other small insects. Since workers are only 3-5mm, prey items should be appropriately sized. Feed protein a few times per week, and keep sugar sources available at all times. Fresh fruit can also be offered occasionally. Remove uneaten prey after 24-48 hours to prevent mold issues.

Temperature and Seasonal Care

As a tropical species from Colombia and Venezuela, Camponotus dalmasi requires warm conditions year-round. Maintain nest temperatures between 24-28°C for optimal brood development. A heating cable placed on top of the nest creates a gentle thermal gradient. Room temperature around 22-24°C is acceptable, but cooler conditions will slow development significantly. Unlike temperate species, they do not require true hibernation. ^[2]

Colony Founding and Development

Camponotus queens are typically claustral, they seal themselves in a chamber and raise their first workers on stored fat reserves. However, founding behavior has not been specifically documented for this species. A newly mated queen should be placed in a test tube setup with a water reservoir, then left undisturbed for several months until the first workers emerge. After the first workers appear, you can begin offering tiny amounts of sugar water and small protein items near the nest entrance. Do not disturb the queen during this critical period, vibrations and light can cause her to abandon or consume the brood.

Behavior and Temperament

Camponotus dalmasi is considered one of the more docile carpenter ant species, showing minimal aggression toward keepers. Workers are active foragers, both on the ground and likely climbing vegetation given their subgenus (Myrmobrachys) tendencies. They are not known for aggressive swarming, while they may spray formic acid as a defense, the small worker size means it's rarely noticeable to humans. Their small size makes them excellent escape artists, so use proper barrier methods. They are not particularly shy and will readily explore outworlds once established. The unique elevated dorsopropodeo (the hump on their back) is visible on major workers. ^[3][2]
