Polyrhachis oedacantha

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Tropical rainforests in Borneo, Indonesia, and the Philippines, specifically in the Maliau Basin Conservation Area ^[2][1]
• Colony Type: Likely monogyne (single queen) based on typical Polyrhachis patterns, but unconfirmed for this species
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements in research
  • Worker: Size data unavailable, no total length measurements in research
  • Colony: Colonies can reach several hundred workers, inferred from Polyrhachis genus patterns
  • Growth: Moderate
  • Development: Estimated 6-8 weeks at optimal temperatures, inferred from related Formicinae species ^[1] (Development may vary with temperature, direct measurements not available for this species)
• Antkeeping:
  • Temperature: Keep at 24-28°C with a gradient using a heating cable, as these are tropical ants ^[1]
  • Humidity: Keep nest substrate consistently moist but not waterlogged, with some drier areas available ^[1]
  • Diapause: No, tropical species do not require hibernation ^[1]
  • Nesting: Prefer Y-tong, plaster, or naturalistic nests with damp substrate to retain humidity ^[1]
• Behavior: Generally calm but will defend nest with formic acid spray from acidopore, like other Formicinae. Workers are active foragers with moderate escape risk, use standard barriers ^[1]
• Common Issues: drying out of substrate can kill colony, monitor moisture regularly, temperatures below 22°C can stop brood development, maintain warmth, wild-caught colonies may carry parasites, quarantine if possible, overfeeding can cause mold, remove uneaten food promptly, tropical species do not tolerate cold, avoid air conditioning or windows

Housing and Nest Setup

Use Y-tong, plaster, or naturalistic nests with damp substrate to maintain humidity. Ensure tight connections to the outworld and avoid acrylic nests. These ants are not strong climbers, so standard barriers like fluon work well ^[1].

Feeding and Diet

Offer sugar water or honey water constantly, and protein like small insects twice weekly. Remove uneaten food after 24 hours to prevent mold ^[1].

Temperature and Seasonal Care

Keep at 24-28°C with a heating cable for gradient. Avoid temperatures below 22°C. No hibernation needed for this tropical species ^[1].

Humidity Management

Maintain high humidity with moist substrate, but avoid waterlogging. Use water reservoirs in plaster nests or mist naturalistic setups ^[1].

Behavior and Temperament

Calm but defensive with formic acid spray. Spines deter predators. Workers forage actively with moderate escape risk ^[1].
