Camponotus strangulatus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to the Malagasy region, Madagascar, Grand Comore and Moheli (Comoros), Mayotte, and Aldabra (Seychelles). In Madagascar it occupies rainforest, littoral rainforest, dry forest, spiny forest, montane rainforest, Uapaca woodland, and human-modified habitats. Nests in rotten logs, dead branches, under stones, and in ground ^[1][2].
• Colony Type: Colony structure unconfirmed. No specific research on queen number found for this species.
• Size & Growth:
  • Queen: Size data unavailable for this species
  • Worker: Minor workers: ~4-6mm, major workers: 6-10mm ^[1]
  • Colony: Unknown for this species
  • Growth: Moderate, typical for Camponotus genus
  • Development: Development time unconfirmed for this species (As a tropical species, development likely accelerates in warmer temperatures within their range)
• Antkeeping:
  • Temperature: Keep at 22-26°C. As a tropical Malagasy species, they prefer warm conditions. A heating cable on one side of the nest creates a gradient allowing workers to self-regulate.
  • Humidity: Moderate to high humidity (60-80%). Provide a moist nest substrate, these ants inhabit diverse forests including humid rainforest areas. Keep substrate damp but not waterlogged.
  • Diapause: No diapause required. As a tropical species from Madagascar, they do not require hibernation. Maintain year-round warm temperatures.
  • Nesting: Highly adaptable. Provide options like a Y-tong (AAC) nest, plaster nest, or naturalistic setup with multiple chambers. Include both horizontal chambers and vertical climbing structures since they forage at various levels. They accept rotten wood sticks in naturalistic setups ^[1].
• Behavior: Workers are moderately active and forage both on the ground and on vegetation. They are generalist omnivores typical of Camponotus, they collect honeydew from aphids and hunt small insects. Major workers with enlarged heads can defend the colony. They are not particularly aggressive toward keepers but will defend if threatened. Escape risk is moderate, use standard Camponotus escape prevention (fluon on rim edges). Their small worker size means small gaps should be sealed.
• Common Issues: tropical species may decline if temperatures drop below 20°C consistently, colonies may struggle if humidity is too low, dry conditions cause desiccation, slow growth compared to faster-developing genera may frustrate beginners, wild-caught colonies may harbor parasites that affect captive survival, major workers are large but colonies are not fast-growing, patience needed

Nest Preferences and Housing

Camponotus strangulatus shows remarkable flexibility in nesting habits, in the wild they nest in rotten logs and sticks on the ground, dead branches hanging above ground, under stones, and directly in soil. They may also nest in arboreal locations ^[2]. This translates well to captivity. A Y-tong (AAC) nest works well, providing dark chambers that mimic their natural nesting sites. Plaster nests also work if kept adequately moist. For naturalistic setups, you can provide rotten wood pieces or cork bark. The key is offering multiple chambers so the colony can choose where to store brood and where to rest. Since they forage at various heights in the wild, include some vertical elements in the outworld, branches or mesh climbing structures. Keep the nest area humid but ensure ventilation prevents mold buildup.

Feeding and Diet

Like most Camponotus species, C. strangulatus is a generalist omnivore. Workers forage for honeydew from aphids and scale insects in the wild, and hunt small invertebrates. In captivity, offer sugar water or honey as a constant energy source. For protein, provide small insects like fruit flies, small crickets, mealworms, or waxworms. They typically accept most standard ant foods. 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. Minor workers will handle smaller prey items while major workers can tackle larger ones. ^[1]

Temperature and Seasonal Care

As a species endemic to Madagascar, a tropical island, C. strangulatus prefers warm conditions. Keep the nest area at 22-26°C for optimal brood development. A heating cable placed on top of the nest (never underneath where it can dry out substrate) creates a gentle temperature gradient. Room temperature may suffice if your home stays in the low-mid 20s°C. Unlike temperate species, they do not require a winter diapause. However, they may show reduced activity during cooler periods. Avoid temperatures below 20°C for extended periods, and keep them away from air conditioning vents or cold windows. Consistent warmth year-round supports healthy colony growth. ^[1]

Behavior and Colony Dynamics

This species develops through minor and major worker castes. Major workers have distinctly enlarged heads and are larger overall, they serve as defenders and can process tougher food items. Workers forage actively, searching for sugar sources and prey. They are not particularly aggressive toward keepers but will bite if provoked. The colony will establish a foraging territory and become more active as it grows. Major workers typically appear after the colony reaches several dozen workers. Expect moderate growth, Camponotus species are not as fast as some genera like Pheidole, but they build lasting colonies that can live for many years with proper care. ^[1]
