Pheidole sava

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Montane rainforest in Madagascar at 1350 m elevation, specifically in Parc National de Marojejy. Nests located in rotten logs and root mat ^[1].
• Colony Type: Unknown, colony structure has not been documented for this species.
• Size & Growth:
  • Queen: Size data unavailable.
  • Worker: Size data unavailable.
  • Colony: Unknown.
  • Growth: Unknown.
  • Development: Unknown, not documented for this species. (No specific data is available.)
• Antkeeping:
  • Temperature: Based on montane rainforest origin at 1350 m, likely cool (around 20-24 °C) and stable. Avoid temperatures above 28 °C ^[1].
  • Humidity: High humidity is required. Keep nest substrate moist but not waterlogged. Natural habitat is consistently damp montane rainforest ^[1].
  • Diapause: Unknown, Madagascar species likely do not require diapause, but no specific data.
  • Nesting: Prefers decaying wood (rotten logs, root mat) in nature. In captivity, Y‑tong or plaster nests that hold moisture are suitable. Test tubes work for founding if kept humid ^[1].
• Behavior: No specific behavior data published. Based on genus patterns, they are generalist feeders and non‑aggressive, but this is unconfirmed.
• Common Issues: maintaining high humidity without mold is challenging., overheating risk due to montane origin, keep below 28 °C., developing from a small founding colony makes them sensitive to disturbance., lack of published care data means keeper must observe and adjust.

Nest Preferences and Housing

In the wild, Pheidole sava nests in rotten logs and root mat in montane rainforest ^[1]. To replicate this, use a nest material that retains moisture, such as Y‑tong or plaster. Keep the substrate damp but not waterlogged. A test tube setup with a water reservoir can work for founding, but the nest must be kept dark and humid. Avoid direct sunlight and drafts. Provide a water source in the outworld ^[1].

Feeding and Diet

No specific dietary data is available for P. sava. Being a Pheidole, it likely accepts a generalist diet: small insects (fruit flies, small crickets) and sugar sources (honey water, sugar water). Major workers may process seeds, but this is unconfirmed. Offer varied food and remove uneaten prey within 24-48 hours to avoid mold.

Temperature and Seasonal Care

Given the montane rainforest habitat, keep the temperature around 20-24 °C ^[1]. Avoid temperatures above 28 °C. A temperature gradient (using a small heating cable) allows workers to choose their preferred zone. True diapause is not likely, but a slight winter reduction to ~18 °C may be tried, no data supports this.

Colony Founding and Development

Founding behavior is unconfirmed. If claustral (typical for many Pheidole), the queen would seal herself in to raise the first workers using stored reserves. Development time from egg to worker is unknown, keep the founding chamber dark and undisturbed. The colony will likely grow slowly, major workers appear as the colony matures.

Behavior and Temperament

No specific published observations. Based on genus, workers are likely active foragers, recruiting nestmates via chemical trails. Aggression is probably low, but they will defend the nest. The species has a physical caste system (minor and major workers). Activity is probably diurnal.
