Temnothorax chunfen

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Yunnan Province, China, Deqin County at 2260 m elevation in dry-warm valley shrubland ^[1]
• Colony Type: Likely single-queen (monogyne) based on typical Temnothorax patterns, but this has not been confirmed. Ergatoid replacement queens may occur in related species.
• Size & Growth:
  • Queen: ~4-5 mm, inferred from genus proportions
  • Worker: 2.4 mm total length ^[1]
  • Colony: Up to 300 workers, inferred from typical Temnothorax colony sizes
  • Growth: Moderate
  • Development: 6-10 weeks, inferred from related species (No direct development data exists, this estimate is based on other small Myrmicinae)
• Antkeeping:
  • Temperature: 20-24°C, based on the dry-warm shrubland habitat at 2260 m elevation ^[1]. Avoid extreme heat, room temperature works well.
  • Humidity: Allow the nesting substrate to dry slightly between rehydrations, as the natural habitat is dry-warm shrubland ^[1]. Avoid constant moisture.
  • Diapause: Likely requires a winter rest period due to the temperate high-elevation origin ^[1]. If kept, provide 2-3 months at 10-15°C.
  • Nesting: Y-tong (AAC) or 3D-printed nests with narrow chambers scaled to their tiny size. Small test tubes work for founding. Avoid large open spaces.
• Behavior: Peaceful and docile. Workers forage on plants for honeydew ^[2]. Their subfamily (Myrmicinae, Crematogastrini) uses a smearing venom defense, they have a modified flattened stinger that wipes venom onto enemies rather than piercing. They are harmless to humans. Escape prevention is critical due to their 2.4 mm size.
• Common Issues: escape prevention is critical, 2.4 mm workers squeeze through tiny gaps, use fine mesh and tight seals, slow colony growth requires patience, don't expect rapid expansion, test tubes may dry out quickly, monitor moisture levels weekly, improper hibernation can weaken colonies, provide a 2-3 month cool period, wild-caught colonies may carry parasites, quarantine new colonies

Housing and Nest Setup

Based on the dry-warm shrubland habitat ^[1], provide a nest that allows the substrate to dry out between waterings. Y-tong (AAC) nests with narrow chambers are ideal, the tight passages match their natural preferences for small cavities. Test tube setups work for founding but monitor moisture carefully, as small tubes evaporate faster. Avoid large, open spaces, these tiny ants feel exposed and may not use them. Include a dry area in the nest to mimic their native conditions.

Feeding and Diet

In nature they forage on plants ^[2], likely collecting honeydew from aphids or scale insects. Offer sugar water or honey water as a constant energy source. For protein, provide tiny live prey such as fruit flies, springtails, or other micro-arthropods. Workers are 2.4 mm and cannot handle large insects. Feed protein 2-3 times per week, removing uneaten prey after 24 hours to prevent mold.

Temperature and Seasonal Care

Maintain temperatures between 20-24°C. The 2260 m elevation and dry-warm shrubland habitat ^[1] suggest they prefer moderately warm conditions without extreme heat. Room temperature works well. If you want to simulate their natural cycle, provide a 2-3 month diapause period at 10-15°C during winter. This rest period likely supports colony health. Do not skip hibernation, it may weaken colonies over time.

Escape Prevention

This is the most critical aspect, workers are just 2.4 mm and can squeeze through gaps that seem impossible. Use fine mesh (0.5 mm or tighter) on all ventilation holes. Apply fluon or similar barriers to rim edges. Check lid seals regularly, standard test tube caps may not seal tightly enough. A second containment layer (e.g., a foraging box with sealed edges) provides insurance. Never underestimate their escape ability.

Colony Development

As a newly described species (2024), specific development data is unavailable. Based on related Temnothorax species, expect 6-10 weeks from egg to first worker at 20-24°C. The first workers (nanitics) will be smaller than mature workers. Colony growth is moderate, a healthy colony may take 1-2 years to reach 50-100 workers. Patience is key with these small species.
