Camponotus claveri

Camponotus claveri

Camponotus claveri is a medium-sized ant species from Madagascar, recently described in 2022. Workers measure 4-6mm (minors) and 7-9mm (majors), with a shiny black body and reddish-brown head and mesosoma. This species belongs to the Camponotus repens species group and is found only in Madagascar, where it nests in soil, under stones, and on the ground at elevations between 830-1987 meters. The species is notable for its adaptability, it thrives in both montane rainforest and open habitats including Uapaca woodland, eucalyptus plantations, shrubland, and even urban areas. It was named in honor of collector Claver Marotafika Randrianandrasana.

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Madagascar, found in montane rainforest and open habitats including Uapaca woodland, eucalyptus plantation, shrubland, and deciduous dry forest, plus urban areas. Nests in soil, under stones, and on the ground at elevations of 830-1987m ^[1][2].
• Colony Type: Colony structure is unconfirmed. Based on typical Camponotus patterns, likely single-queen colonies (monogyne).
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 9-12mm based on genus patterns, direct measurements not available
  • Worker: Minors: 4-6mm, Majors: 7-9mm ^[1]
  • Colony: Estimated several thousand workers based on typical Camponotus colony growth
  • Growth: Moderate, typical for Camponotus genus
  • Development: 6-10 weeks based on typical Camponotus development at optimal temperature (Development time estimated from genus-level data, specific timing for this species has not been directly studied)
• Antkeeping:
  • Temperature: Based on montane habitat (830-1987m elevation), these ants prefer cooler conditions than typical tropical ants. Aim for 18-24°C with a gentle gradient. They likely tolerate temperatures from 15°C to 28°C given their high-elevation range.
  • Humidity: Moderate to high humidity. Montane rainforest origin suggests 60-80% relative humidity. Keep nest substrate consistently moist but not waterlogged, with some drier areas available.
  • Diapause: Unknown, Madagascar has less extreme seasonal variation than temperate regions, but the high elevation suggests some seasonal adjustment may be beneficial. Monitor colony activity patterns.
  • Nesting: Natural nesting in soil, under stones, and on the ground. In captivity, a Y-tong (AAC) nest or plaster nest works well. Provide a moisture reservoir and keep the nest area humid. Given their montane origin, avoid overheating.
• Behavior: Typical Camponotus temperament, generally calm and not overly aggressive. Workers are moderately active foragers. Majors serve as repletes (living food storage) and help with colony defense. Escape risk is moderate due to their medium size, standard escape prevention measures are sufficient. They are primarily nocturnal or crepuscular foragers.
• Common Issues: high elevation origin means they can overheat easily, avoid temperatures above 28°C, wild-caught colonies may carry parasites that can devastate captive colonies, slow initial colony growth during claustral founding phase can lead to overfeeding or disturbance, test tube setups must have adequate moisture without flooding, montane species need stable humidity

Nest Preferences and Setup

In the wild, Camponotus claveri nests in soil, under stones, and directly on the ground surface. This tells us they prefer nest sites with some moisture access and protection from extreme conditions. For captive care, a Y-tong (acrylic) nest or plaster nest works well, both hold humidity consistently and allow you to monitor the colony. Test tube setups can work for founding colonies, but monitor moisture levels carefully as montane species are sensitive to both drying out and flooding. Provide a water tube or moisture reservoir, and consider adding a small outworld for foraging. Avoid nests that overheat easily, place them away from direct sunlight and heating elements that could create hot spots. ^[1][2]

Feeding and Diet

Camponotus claveri is a typical Camponotus species, they need a balanced diet of sugars and protein. Offer sugar water, honey, or diluted maple syrup as a constant carbohydrate source. For protein, provide insects like fruit flies, small crickets, mealworms, or other appropriately-sized prey. They will likely accept most standard ant foods. Feed protein 2-3 times per week, and keep sugar available at all times. Remove uneaten prey after 24-48 hours to prevent mold. Given their montane origin, they may have slightly lower metabolic demands than lowland tropical species, don't overfeed.

Temperature and Seasonal Care

This is one of the most important aspects of keeping Camponotus claveri successfully. Their natural habitat at 830-1987m elevation in Madagascar means they prefer cooler conditions than most ant species. Keep the nest area at 18-24°C, with a slight gradient allowing workers to choose their preferred temperature. They can tolerate brief periods down to around 15°C and up to 28°C, but prolonged exposure to higher temperatures can be fatal. Use a heating cable only if your room temperature falls below 18°C, and place it on the TOP of the nest (not underneath) to avoid evaporating moisture too quickly. Room temperature in most homes is likely suitable. Watch for workers clustering near or avoiding heat sources to fine-tune their ideal spot. ^[1]

Behavior and Colony Dynamics

Camponotus claveri shows typical Camponotus behavior, they are generally peaceful, with majors serving as repletes (living food storage) and defenders. Workers are moderately active, primarily foraging during cooler hours (evening, night, or early morning). The colony will establish a clear division of labor with minors handling most foraging and brood care, while majors defend the nest and store food. Majors are significantly larger (7-9mm) than minors (4-6mm), giving them a distinctive appearance. Colonies grow moderately, expect the first workers (nanitics) within 6-10 weeks of founding, with gradual growth over the first year. They are not aggressive toward keepers and their sting is mild, though larger majors could potentially penetrate skin. ^[1]

Growth and Development

As a recently described species (2022), specific development data for Camponotus claveri is not available. However, based on typical Camponotus patterns, you can expect: eggs to larvae in about 2 weeks, larvae to pupae in another 2-3 weeks, and pupae to workers in 2-3 weeks more, totaling roughly 6-10 weeks from egg to first worker at optimal temperature (around 20-22°C). The founding queen will seal herself into a claustral chamber and not leave to forage, she lives entirely on stored fat reserves until her first workers emerge. These first workers (nanitics) will be smaller than normal workers. Growth is moderate, don't expect rapid colony expansion. Focus on providing stable conditions rather than trying to speed up development with higher temperatures, as overheating is a greater risk than slow growth.
