Polyrhachis tianjingshanensis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Guangdong Province, China, in forest habitat at 450 m elevation ^[1].
• Colony Type: Colony structure is unconfirmed. Based on Polyrhachis patterns, likely single-queen colonies, but no specific data available.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: ~11.4-11.7 mm ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Moderate, inferred from genus patterns
  • Development: Estimated 8-12 weeks based on genus patterns for similar species (Development time may vary with temperature and nutrition.)
• Antkeeping:
  • Temperature: Keep at warm temperatures, roughly 24-28°C, based on southern China habitat ^[1]
  • Humidity: Keep nest substrate consistently moist but not waterlogged, based on forest habitat ^[1]
  • Diapause: Likely required during winter, based on geographic range and genus patterns
  • Nesting: Prefers nesting in rotting wood or under bark, based on forest habitat ^[1]
• Behavior: Generally docile and non-aggressive, based on genus patterns. Escape risk is moderate due to their size.
• Common Issues: incorrect humidity levels can lead to brood failure or mold growth, improper diapause management may stress the colony, wild-caught colonies may carry parasites or diseases that are hard to treat

Housing and Nest Setup

Use a Y-tong (AAC) nest or plaster formicarium to retain moisture and provide dark chambers. Include sections of rotting wood or bark to mimic their natural forest habitat ^[1]. Ensure nest chambers are large enough for these 11+ mm workers. Secure all connections to the outworld to prevent escapes, as they are strong ants.

Feeding and Diet

Offer a varied diet: sugar water or honey constantly, and protein like mealworms or crickets 2-3 times per week. Based on genus patterns, they are omnivorous. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Seasonal Care

Maintain nest temperatures around 24-28°C for optimal brood development. During winter, reduce temperatures to 15-18°C for 2-3 months to simulate diapause, based on genus patterns. Monitor colony activity and avoid feeding during deep hibernation.

Humidity Management

Keep the nest substrate consistently moist but not waterlogged, based on their forest habitat ^[1]. In plaster or Y-tong nests, maintain a water reservoir and check weekly. Balance humidity with ventilation to prevent mold growth.

Behavior and Handling

These ants are generally docile and may retreat when disturbed. They lack a functional sting but can spray formic acid as a defense mechanism, typical of Formicinae. Their large size makes them easy to handle, but ensure secure enclosures to prevent escapes.
