Camponotus zavo

Camponotus zavo

Camponotus zavo is a medium-sized carpenter ant species endemic to eastern Madagascar. Workers are mostly black with a dark brown abdomen, and they have a smooth, shiny appearance on the head and body. Minor workers are slender with long antennae that extend past the back of the head, while major workers have wider heads and shorter antennae. This species belongs to the Camponotus edmondi species group and was formally described in 2016 ^[1]. They build their nests in dead twigs above the ground and forage on the lower parts of vegetation in Madagascar's rainforests and montane forests ^[1].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Eastern Madagascar, from lowland rainforest at 175m elevation up to montane forest habitats at 1520m ^[1]. In the wild, they nest in dead twigs above the ground and forage on lower vegetation.
• Colony Type: Single-queen colonies (monogyne). This follows typical Camponotus colony structure.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 12-15mm based on genus Camponotus patterns
  • Worker: Minor workers: 5-8mm, Major workers: 8-12mm ^[1]
  • Colony: Likely moderate colony size, similar to related Camponotus species, estimated several hundred workers
  • Growth: Moderate, typical for Camponotus genus
  • Development: Estimated 6-8 weeks at optimal temperature based on genus-level Camponotus data (Development time is temperature-dependent, warmer conditions within range accelerate development)
• Antkeeping:
  • Temperature: Keep at 22-26°C. The wide elevation range (175m to 1520m) suggests they can tolerate a range, but aim for warm room temperature. A heating cable on one side of the nest creates a useful gradient.
  • Humidity: Moderate to high humidity (60-80%). These are forest ants from Madagascar, so they prefer damp conditions. Keep the nest substrate consistently moist but not waterlogged.
  • Diapause: No, as a tropical Madagascar species, they do not require hibernation. Maintain consistent temperatures year-round.
  • Nesting: They naturally nest in dead twigs above ground, so they do well in Y-tong (AAC) nests, plaster nests, or naturalistic setups with twigs/branches. Tight-fitting connections between nest and outworld are important since they forage on vegetation.
• Behavior: Generally calm and not aggressive. Like most Camponotus, they are moderate foragers that will explore their outworld for food. Major workers can deliver a bite if threatened, but they are not particularly aggressive. Escape prevention should be good, they are medium-sized ants, but check that lids fit tightly.
• Common Issues: colonies may stall if temperatures drop below 20°C for extended periods, test tube setups may dry out quickly since they prefer humid conditions, monitor moisture regularly, slow founding phase is normal for Camponotus, don't disturb the queen during claustral founding, wild-caught colonies may carry parasites that affect captive survival

Housing and Nest Setup

Camponotus zavo does well in Y-tong (acrylic) nests or plaster nests that can hold moisture. Since they naturally nest in dead twigs above ground, you could also create a naturalistic setup with small twigs or branches. The key is providing a nest that stays humid but has good ventilation to prevent mold. Connect the nest to a foraging area (outworld) that has plants or vegetation they can climb on, since they naturally forage on lower vegetation. Use a water test tube as a humidity source attached to the nest. A small outworld works well for this medium-sized species. ^[1]

Feeding and Diet

Like other Camponotus species, C. zavo is omnivorous. Offer them sugar water or honey as a constant energy source. For protein, provide insects like fruit flies, small crickets, mealworms, or other small arthropods. They will also eat small amounts of seeds or plant matter. Feed them protein 2-3 times per week, and keep sugar water available at all times. Remove uneaten prey after 24-48 hours to prevent mold. ^[1]

Temperature and Seasonal Care

Maintain temperatures between 22-26°C. The species' wide elevation range in Madagascar (175m to 1520m) indicates they can adapt to different conditions, but they do best in warm, stable temperatures. Avoid temperatures below 20°C for extended periods. Since they are a tropical species from Madagascar, no hibernation or diapause is needed, keep them at consistent temperatures year-round. A heating cable on one side of the nest can create a gradient if your room temperature runs cool. ^[1]

Colony Founding and Growth

Founding queens are claustral, they seal themselves in a chamber and raise the first brood alone using stored fat reserves. Do not disturb a founding queen during this time. The first workers (nanitics) will be smaller than normal workers. After the first workers emerge, the colony will grow gradually. Camponotus colonies are long-lived, with queens potentially living 10-20 years. Growth is moderate, expect several months before you see significant numbers of workers. Major workers develop as the colony matures. ^[1]

Behavior and Handling

These ants are generally calm and not prone to aggressive swarming. Major workers can bite if threatened, but the bite is mild compared to some other ants. They are moderate foragers that will search for food in the outworld. They are not strong climbers on smooth surfaces, but they do well climbing on vegetation or textured surfaces. Escape prevention should be adequate for their size, check that all connections are secure and lids fit tightly. ^[1]
