Polyrhachis dubia

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Cameroon in the Afrotropical region. Collected from Mbalmayo in November 1993 ^[1]. Specific habitat type is unconfirmed.
• Colony Type: Unconfirmed. Polyrhachis species are typically monogyne (single queen colonies), but no data exists for this specific species.
• Size & Growth:
  • Queen: Size unknown, inferred from Polyrhachis genus (~6-9 mm)
  • Worker: Size unknown, inferred from Polyrhachis genus (~4-5 mm)
  • Colony: Unknown, no colony size data available.
  • Growth: Unknown
  • Development: Unconfirmed. Based on typical Polyrhachis patterns, estimate 6-10 weeks at optimal temperature. (No direct development data exists for this species.)
• Antkeeping:
  • Temperature: Start around 22-26°C and observe colony response. Provide a thermal gradient if possible.
  • Humidity: Keep substrate moderately moist. Aim for consistent moisture without waterlogging.
  • Diapause: Unknown for this species. Many tropical Polyrhachis do not require hibernation.
  • Nesting: No specific data. Use soil substrate or Y-tong/plaster nests with moderate chambers scaled to small worker size.
• Behavior: Temperament: Likely docile based on genus patterns. Escape risk: Moderate due to small size. Defense: Lacks a functional sting, bites and sprays formic acid from an acidopore (based on subfamily Formicinae).
• Common Issues: lack of biological data makes care challenging and may lead to colony failure., founding behavior is unconfirmed, so queen introduction may be difficult., growth rate is unknown, making it hard to assess colony health., temperature and humidity requirements are estimates, incorrect settings may harm the colony., diet preferences are unconfirmed, experimentation is needed to avoid malnutrition.

Getting Started with Polyrhachis dubia

Since this species was only described in 2016 and has no published biological data ^[1], keeping it requires careful observation. Start with a small colony or queen if available, and adjust care based on colony response. Worker size is small, so nests should have appropriately scaled chambers. Test tube setups can work for founding, but monitor humidity carefully.

Housing and Nest Setup

No specific nesting data exists for Polyrhachis dubia. Base your setup on related Polyrhachis species. A naturalistic soil setup or Y-tong/plaster nest with moderate chambers works well. Ensure escape prevention due to small size by securing connections and outworld barriers.

Feeding and Diet

No specific dietary studies exist. Polyrhachis species are typically omnivorous. Offer sugar water or honey for carbohydrates, and small insects like fruit flies for protein. Experiment to see what your colony accepts best.

Temperature and Humidity Management

No thermal data exists for this species. Start with a temperature range of 22-26°C and observe colony behavior. For humidity, keep the nest substrate consistently moist but not waterlogged.

Understanding the Challenges

This species has no established care protocols. Every aspect of care requires discovery through observation and experimentation. Document your observations carefully to help build knowledge for the antkeeping community.
