Ponera longlina

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Endemic to Yunnan Province, China, found in mountain rain forest at around 1050m elevation ^[2][1].
• Colony Type: Based on Ponera genus patterns, likely monogyne colonies with a single queen.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Ponera genus as ~3-4mm total length.
  • Worker: 2.2mm total length ^[2]
  • Colony: Up to 300 workers, inferred from Ponera genus patterns.
  • Growth: Slow
  • Development: Estimated 8-12 weeks. (Development is slow, expect several months from founding to first workers.)
• Antkeeping:
  • Temperature: Keep cool, around 18-22°C. Based on mountain rainforest origin, they prefer cooler temperatures.
  • Humidity: High humidity is essential, keep nest substrate consistently moist but not waterlogged.
  • Diapause: Likely requires a winter diapause of 2-3 months at 10-15°C.
  • Nesting: Provide a humid nest with fine substrate, such as a test tube setup or Y-tong nest.
• Behavior: Ponera longlina is cryptic and slow-moving. Workers are not aggressive but have a sting as part of Ponerinae subfamily, though it is not significant to humans due to their small size. Escape prevention is critical due to their tiny size.
• Common Issues: Escapes are likely due to very small size, use fine mesh barriers., Slow growth can lead to overfeeding and mold, feed sparingly., High humidity requirements can cause mold if ventilation is poor., Wild-caught colonies may have parasites., Founding queens are difficult to establish.

Housing and Nest Setup

Ponera longlina requires a small, humid nest setup. A test tube setup works well for founding colonies. For established colonies, a Y-tong nest or small plaster nest is suitable. Worker size is 2.2mm, so use tight-fitting barriers and fine mesh to prevent escapes ^[2]. Provide a small outworld for feeding, but keep it minimal due to their cryptic nature.

Feeding and Diet

Ponera longlina is predatory and should be fed small live prey such as fruit flies, springtails, or pinhead crickets. Prey should be appropriately sized, no larger than the ant itself. Feed small amounts 2-3 times per week, removing uneaten prey after 24 hours to prevent mold. Sugar sources are unlikely to be accepted.

Temperature and Seasonal Care

Keep Ponera longlina cool at 18-22°C, based on their mountain rainforest origin. Avoid heating elements that might overheat the nest. In winter, provide a diapause period of 2-3 months at 10-15°C to simulate natural cycles.

Colony Founding

Founding behavior is unconfirmed for this species. If you obtain a queen, provide a small, humid test tube chamber and keep her in darkness with minimal disturbance. Founding success rates are typically low, so expect some losses.

Behavior and Observation

Ponera longlina is cryptic and slow-moving. Workers remain hidden within the nest most of the time and are not aggressive. They have a sting as part of Ponerinae subfamily, but it is not significant to humans due to their small size. Observation is challenging but rewarding for patient keepers.
