Camponotus bevohitra

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Montane rainforest in central high plateau of Madagascar, specifically known from Réserve Spéciale d'Ambohitantely at 1410m elevation ^[1][2].
• Colony Type: Likely monogyne based on typical Camponotus patterns, colony type is unconfirmed for this species.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Mayria subgenus patterns as approximately 12-16mm
  • Worker: Minor workers: approximately 5-8mm, Major workers: approximately 8-12mm, sizes estimated from morphology ratios ^[1]
  • Colony: Up to several hundred workers (estimated)
  • Growth: Moderate, standard Camponotus development timeline
  • Development: Estimated 6-8 weeks at optimal temperature based on genus-level Camponotus development data (Development time is estimated from related Camponotus species as no direct species-specific data exists. Temperature will significantly affect development speed.)
• Antkeeping:
  • Temperature: Keep at 22-26°C. As a montane species from Madagascar, they prefer moderate temperatures rather than extreme heat. A gentle gradient allowing workers to self-regulate is ideal ^[1].
  • Humidity: Moderate humidity (50-70%). Their arboreal nesting in dead twigs suggests they prefer drier conditions than ground-nesting ants. Provide a moisture gradient so ants can choose their preferred zone.
  • Diapause: Likely required. As a montane Madagascar species, they likely experience seasonal temperature changes. Provide a cool period (15-18°C) for 2-3 months during winter months, reducing feeding frequency.
  • Nesting: Arboreal specialists, they naturally nest in dead twigs and branches above ground. Y-tong (AAC) nests or acrylic nests with horizontal chambers work well. Avoid fully enclosed underground-style formicaria. Provide twigs/branches or simulate these conditions with appropriate nest architecture ^[1][2].
• Behavior: Generally calm and non-aggressive compared to some Camponotus species. Workers forage on lower vegetation in the wild, suggesting moderate activity levels. They are not known for being particularly defensive or aggressive toward keepers. Escape risk is moderate, use standard Camponotus escape prevention (fluon on edges). This species lacks a functional sting, instead, they bite and spray formic acid from their acidopore as their defense mechanism, typical of the Formicinae subfamily.
• Common Issues: arboreal nesting requirements mean standard underground nests may cause stress or improper humidity levels, montane origin means they may not tolerate high temperatures, avoid overheating above 30°C, slow colony growth can frustrate beginners, patience is key with this species, wild-caught colonies may have parasites or diseases that affect captive survival, humidity control is critical, too wet leads to mold, too dry causes desiccation

Nest Preferences and Housing

Camponotus bevohitra is an arboreal-nesting species, meaning they naturally live in dead twigs and branches above ground rather than underground ^[1]. This is the most critical aspect of their care. In captivity, they do best in Y-tong (AAC) nests or acrylic nests designed with horizontal chambers that simulate their natural twig environment. Traditional fully enclosed underground formicaria with deep chambers are not ideal for this species. The nest should have good ventilation while maintaining moderate humidity. You can also provide actual dead twigs or branches in a naturalistic setup, though these can be difficult to maintain. The key is providing a dry, airy nest environment with chambers scaled to their size, not too large, as they prefer cozy spaces. Ensure the nest has multiple chambers connected by narrow passages to mimic the tight spaces of a twig interior.

Feeding and Diet

Like other Camponotus species, C. bevohitra is omnivorous and will accept a variety of foods. In the wild, they forage on lower vegetation, likely collecting honeydew from aphids and hunting small insects ^[1]. In captivity, offer a balanced diet: sugar water or honey as an energy source (always available), and protein sources like mealworms, small crickets, or other insects 2-3 times per week. Since they forage on vegetation, they may also accept plant-based foods or fruit. Remove uneaten prey after 24-48 hours to prevent mold. During founding, the claustral queen will not need food, she relies entirely on stored fat reserves until her first workers (nanitics) emerge. Once workers are active, begin offering small amounts of sugar water and tiny protein pieces.

Temperature and Seasonal Care

As a montane species from central Madagascar, C. bevohitra prefers moderate temperatures rather than heat. Keep the nest area at 22-26°C, with a slight gradient so workers can regulate their own temperature. Avoid temperatures above 30°C, as this can stress or kill the colony. Room temperature (around 22-24°C) is often ideal for this species. During winter months (roughly November-February in the Northern Hemisphere), reduce temperatures to 15-18°C to simulate their natural seasonal cycle. This cool period mimics the cooler montane conditions they experience in Madagascar. During this time, reduce feeding frequency significantly, perhaps once every two weeks, as the colony will be less active. Do not feed heavily during diapause as uneaten food will mold in the cooler, slower-moving air. ^[1]

Colony Founding and Development

Camponotus bevohitra likely follows typical claustral founding behavior based on genus patterns, though specific founding behavior is unconfirmed for this species. The queen seals herself into a small chamber and does not leave to forage during the founding period. She relies entirely on her stored fat reserves (metabolic energy) to survive and raise her first brood. This means you do not need to feed a founding queen at all, doing so can actually cause problems by attracting pests or causing humidity issues. The founding chamber should be small and snug, a test tube with a cotton barrier works well. The queen will remain sealed in, laying eggs and tending to the brood until her first workers emerge. This process typically takes 6-8 weeks at optimal temperature (around 24°C), though it may take longer if temperatures are cooler. The first workers (nanitics) are usually smaller than subsequent workers. Once workers are foraging, you can begin connecting the founding setup to an outworld and offer food. ^[1]

Behavior and Temperament

This species is generally calm and manageable in captivity. They are not particularly aggressive or defensive, making them suitable for antkeepers who want to observe interesting behavior without high escape risk or painful stings. Workers are moderately active and will forage throughout the nest and outworld. The major workers, while larger, are not particularly aggressive and can be handled with care if necessary. Their natural foraging on lower vegetation suggests they explore their environment methodically rather than rushing frantically. As members of the Formicinae subfamily, they lack a functional sting. Instead, their defense mechanism involves biting the target and spraying a stream of concentrated formic acid from an acidopore into the wound. This is not dangerous to healthy humans. Escape prevention should be standard (fluon on rim edges) but does not require the extreme measures needed for tiny species. ^[1]
