Polyrhachis phidias

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Forest zones of West and Central Africa, including Nigeria, Equatorial Guinea, Central African Republic, and Tanzania ^[1]. In nature, they likely nest in rotting wood or under bark in humid forest environments ^[1].
• Colony Type: Colony structure is unconfirmed. Based on typical Polyrhachis genus patterns, likely single-queen (monogyne) colonies, but this has not been directly documented for this species.
• Size & Growth:
  • Queen: Queen body size data unavailable.
  • Worker: Workers are 4.9-5.1 mm in total length ^[1].
  • Colony: Colony size is unconfirmed, but based on related species in the militaris group, colonies may reach several hundred workers at maturity.
  • Growth: Growth rate is unconfirmed.
  • Development: Development timeline is unconfirmed. Based on genus patterns, egg to worker may take 8-12 weeks at warm temperatures. (This is an estimate based on genus-level data, as no species-specific development studies exist.)
• Antkeeping:
  • Temperature: As a forest species, keep them warm. A temperature gradient around 24-28°C is typical for similar species, but specific needs are unconfirmed. Avoid prolonged cool periods below 20°C.
  • Humidity: Forest species require high humidity. Keep the nest substrate consistently moist but not waterlogged. Provide a water source and adjust based on setup conditions.
  • Diapause: Diapause requirements are unknown for this species, as no data exists on seasonal behavior.
  • Nesting: Based on genus patterns, they prefer enclosed, humid nests such as Y-tong (AAC), plaster, or naturalistic setups with damp substrate.
• Behavior: Based on genus patterns, workers are generally calm and active foragers. They search for honeydew, nectar, and small insects. Escape risk is moderate due to their size, standard prevention measures are recommended.
• Common Issues: high humidity maintenance can be challenging, improper ventilation leads to mold growth that can kill colonies, temperature drops below 20°C can slow or stop brood development entirely, overfeeding can lead to mold in the nest, so remove uneaten food promptly, lack of protein sources will stunt growth, they need regular insect prey

Housing and Nest Setup

You should use enclosed nest setups that retain humidity, such as Y-tong (AAC) nests or plaster nests with water reservoirs. Based on their forest habitat, provide damp substrate and avoid overly large, open spaces ^[1]. Connect the nest to a foraging area for food access.

Feeding and Nutrition

You can offer a varied diet. Provide constant sugar sources like sugar water or honey, and protein from small insects such as fruit flies or pinhead crickets. Feed protein 2-3 times per week and remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Seasonal Care

Maintain warm conditions, ideally around 24-28°C, using a heating cable or mat to create a gradient. Brood development depends on warmth, cooler temperatures may slow it. Monitor colony activity to adjust temperature as needed.

Humidity Management

Keep humidity high by maintaining moist but not waterlogged substrate. Use a water reservoir connected to the nest and check regularly to rehydrate if dry. Good ventilation helps balance humidity.

Colony Founding

Founding behavior is unconfirmed for this species. You should provide a small, humid chamber for a queen and avoid disturbance during founding.

Behavior and Handling

Workers are active foragers but generally calm. They are diurnal and may use spines defensively. Handle minimally to avoid stress, and use standard escape prevention like Fluon barriers.
