Nylanderia emmae

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Southern China including Zhejiang, Anhui, Sichuan, Hunan, Jiangxi, Guangdong, Hong Kong, and Hainan provinces. Found exclusively in primary forest habitats ^[1][4][5].
• Colony Type: Colony structure is unconfirmed. No data on queen number or social structure available.
• Size & Growth:
  • Queen: 15.2-15.4mm ^[1]
  • Worker: 2.9-3.5mm ^[1]
  • Colony: Unknown, no data on maximum colony size
  • Growth: Moderate, inferred from related Formicinae species
  • Development: Estimated 6-10 weeks at optimal temperature based on typical Formicinae patterns (Specific development data not available for this species, timing may vary with temperature.)
• Antkeeping:
  • Temperature: Keep around 22-26°C with a gentle gradient, inferred from subtropical habitat ^[1]
  • Humidity: Keep substrate moderately moist but not waterlogged, like forest floor conditions
  • Diapause: Likely not required, but a brief cool period (15-18°C for 4-6 weeks) in winter may be beneficial
  • Nesting: Test tubes work well for founding colonies. For established colonies, use nests that maintain moderate humidity, such as plaster or soil-based setups
• Behavior: Workers are active foragers, likely collecting honeydew and small prey. They are not aggressive but have a high escape risk due to their small size (under 4mm)
• Common Issues: escape prevention is critical due to very small size, they can squeeze through tiny gaps, as a primary forest specialist, they may be sensitive to dry conditions, avoid unstable environments, slow growth can frustrate beginners, colonies may take months to establish, wild-caught colonies may carry parasites that can decimate captive populations, overheating is a risk, keep away from direct heat sources and maintain stable temperatures

Housing and Nest Setup

For founding colonies, use a standard test tube setup with water and cotton plug. Once workers emerge, move to a small formicarium that maintains moderate humidity, as this species is a forest specialist. Avoid dry setups, provide a humidity gradient with a moist area. A small outworld allows foraging observation ^[1].

Feeding and Diet

Like most Formicinae, Nylanderia emmae likely accepts a varied diet. Offer sugar water or honey constantly for energy, and protein sources like fruit flies or pinhead crickets 2-3 times per week. Remove uneaten food to prevent mold.

Temperature and Seasonal Care

Keep temperatures around 22-26°C, with a gentle gradient to allow self-regulation. During winter, a brief cool period at 15-18°C for 4-6 weeks may be beneficial. Monitor colony activity for signs of stress ^[1].

Behavior and Colony Dynamics

Workers are active foragers, likely searching for food on the ground and low vegetation. They are not aggressive and will flee from threats. Colonies grow gradually, with queens potentially living many years. Watch for signs of stress like premature worker death ^[1].
