Camponotus jjacquia

Camponotus jjacquia

Camponotus jjacquia is a medium-sized black ant native to southern Madagascar, first described in 2022. Workers are black throughout with a distinctive feature: their entire body is covered in plentiful erect whitish setae (stiff hairs), giving them a somewhat fuzzy appearance. The species belongs to the Camponotus repens species group and the Mayria subgenus. Minor workers measure around 9-11mm in total length, while major workers (soldiers) are larger with a much wider head, reaching around 13-15mm. The petiole (the narrow waist segment) is notably long and low, a key identifying feature. This ant nests in soil and has been collected from various habitats including spiny forest, deciduous forest, and savannah woodland at elevations between 43-923 meters ^[1].

This is a newly described species, so captive husbandry information is limited. However, being a Camponotus species from Madagascar, it represents an exciting addition to the hobby for keepers interested in African and Malagasy ants. The species was named to honor Jean Jacques Rafanomezantsoa, a Malagasy ant collector who contributed to its discovery.

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Southern Madagascar, specifically the Toliara province region. Found in multiple habitat types including Bismarckia woodland, deciduous forest, gallery forest, savannah woodland, spiny forest, and tropical dry forest at elevations of 43-923m ^[1].
• Colony Type: Likely monogyne (single queen colony) based on typical Camponotus patterns. Colony structure has not been directly documented for this species.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 12-16mm based on typical Camponotus queen size ranges
  • Worker: Minor workers: 9-11mm, Major workers: 13-15mm ^[1]
  • Colony: Estimated several hundred to a few thousand workers based on typical Camponotis colony sizes
  • Growth: Moderate, typical for Camponotus genus
  • Development: Estimated 6-8 weeks at optimal temperature based on typical Camponotus development ^[1] (Development time is inferred from genus patterns as no species-specific data exists. Temperature affects development speed significantly.)
• Antkeeping:
  • Temperature: Keep warm at 24-28°C. Based on Madagascar tropical habitat preferences, they prefer warmer conditions. A heating cable on one side of the nest creates a gradient allowing workers to self-regulate.
  • Humidity: Moderate humidity around 50-70%. The species inhabits areas from dry forest to woodland, so avoid overly wet conditions. Keep the nest substrate slightly moist but allow some drying between waterings.
  • Diapause: Unlikely to require true hibernation being a tropical species. However, a slight cool-down period (15-18°C) during winter months may be beneficial to simulate seasonal slowdown, similar to other Malagasy Camponotus.
  • Nesting: Soil-nesting species. In captivity, a Y-tong (AAC) nest or plaster nest works well. Provide a moisture gradient so workers can choose their preferred humidity zone. A test tube setup works for founding colonies.
• Behavior: Typical Camponotus behavior, workers are moderately active foragers, primarily nocturnal or crepuscular. They are not particularly aggressive but will defend the nest if threatened. Major workers serve as soldiers and help process larger prey. Escape risk is moderate due to their medium size, standard barriers work well but ensure lids fit securely. They likely forage for honeydew and small insects in nature.
• Common Issues: new species means limited husbandry information, be prepared to experiment with conditions, tropical origin means they may be sensitive to temperature drops below 20°C, soil-nesting preference means they may struggle in fully artificial nests without appropriate substrate, wild-caught colonies may have parasites that affect captive survival, slow founding phase typical of Camponotus, patience is essential

Nest Preferences and Housing

Camponotus jjacquia is a soil-nesting species found under stones, in leaf litter, and occasionally on tree trunks in nature ^[1]. For captive care, provide a nest setup that allows them to burrow and create chambers. A Y-tong (acrylic and cotton) nest with a dirt section works well, as does a plaster nest with moisture retention capabilities. Test tube setups are suitable for founding colonies, place the tube in a dark area and allow the queen to seal herself in a chamber. Ensure the nest has a moisture gradient so workers can regulate their humidity preferences. The species tolerates a range of nest conditions but prefers consistency over extremes.

Feeding and Diet

Like other Camponotus species, C. jjacquia is likely omnivorous with a preference for sugary liquids and protein. In nature, they probably tend aphids for honeydew and hunt small insects. In captivity, offer sugar water or honey water as a constant energy source. For protein, provide small insects like fruit flies, pinhead crickets, or mealworms. Major workers can tackle larger prey items. Feed protein 2-3 times per week, and keep sugar water available at all times. Remove uneaten prey after 24-48 hours to prevent mold. This species is newly described, so exact food preferences are unknown, be prepared to experiment with different protein sources.

Temperature and Seasonal Care

Being native to southern Madagascar, this species prefers warmer temperatures in the range of 24-28°C. Their natural habitat includes spiny forest and tropical dry forest, which experience warm conditions year-round. Use a heating cable on one side of the nest to create a temperature gradient, this allows workers to move between warmer and cooler areas as needed. Avoid temperatures below 20°C for extended periods, as this species is not adapted to cold. During winter, if room temperature drops significantly, consider using a small heat mat. Unlike temperate species, they likely do not require true hibernation but may show reduced activity during cooler months. ^[1]

Colony Founding and Development

Based on typical Camponotus behavior, the queen likely seals herself in a chamber (claustral founding) and survives on stored fat reserves until her first workers emerge. The founding phase can take 6-8 weeks or longer depending on temperature. First workers (nanitics) are typically smaller than normal workers. The colony will grow slowly at first, with worker numbers increasing gradually over the first year. Major workers (soldiers) typically appear once the colony reaches several dozen workers. Be patient during founding, disturbing the nest too early can cause the queen to abandon or eat her brood. Once workers are established, the colony growth rate typically accelerates.

Behavior and Temperament

Camponotus jjacquia displays typical carpenter ant behavior, workers are moderately active and primarily forage during evening and nighttime hours. They are not particularly aggressive toward keepers but will defend the nest if disturbed. The presence of major workers (soldiers) with larger heads distinguishes this species, and these majors help process larger food items and defend the colony. Workers communicate using chemical pheromone trails when foraging. They are medium-sized ants, so escape prevention is straightforward, standard barrier methods work well. Avoid keeping the colony in direct sunlight or near vibrations, as this can stress the ants.
