Myrmecina carinolateralis

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Xizang (Tibet), western China, high-altitude region ^[1].
• Colony Type: Unconfirmed, no data on queen number or social structure.
• Size & Growth:
  • Queen: size data unavailable.
  • Worker: 2.69-2.75mm ^[1].
  • Colony: Unknown.
  • Growth: Unknown.
  • Development: Unconfirmed. (No direct development data exists for this species. Temperature likely affects development significantly given their high-altitude origin.)
• Antkeeping:
  • Temperature: Likely prefers cool conditions due to high-altitude origin, but exact requirements are unknown. Aim for 18-22°C as a starting guess, but observe the colony and adjust based on behavior. Heating cables are not recommended until more is known.
  • Humidity: Moderate, keep the nest substrate lightly moist but not waterlogged. A moisture gradient may be beneficial.
  • Diapause: Unknown, high-altitude origin suggests a winter rest may be needed, but this is unconfirmed. If attempting, provide 2-3 months at 10-15°C and monitor.
  • Nesting: Y-tong (AAC) or plaster nests with narrow chambers work well for their tiny size. Soil-based naturalistic setups are also suitable. Avoid oversized nests that stress small colonies.
• Behavior: These ants are very small and shy. Workers are not aggressive and likely forage individually. They belong to a group that uses a 'smear' defense, they wipe venom onto attackers rather than stinging, but this is unconfirmed for this species. Escape prevention is critical due to their tiny size, they can fit through gaps under 1mm. They pose no danger to keepers.
• Common Issues: escape prevention is critical due to their 2.7mm size, use fine mesh and seal all gaps., founding method is unknown, queens may not be claustral, making first workers hard to raise., an unstudied creature, any care advice is speculative, and colonies may fail from unknown causes., likely slow growth and stress-prone due to small size, avoid disturbing the nest., no guarantee of diapause requirement, incorrect seasonal care could harm the colony.

Housing and Nest Setup

Because these ants are under 3mm, escape prevention is your top priority. Use a Y-tong (AAC) or plaster nest with narrow chambers scaled to their size, oversized chambers stress tiny colonies. A small container with moist soil also works. Cover any ventilation holes with fine mesh (0.5mm or smaller). Keep the nest humidified but not waterlogged, and ensure some ventilation to prevent mold. A water tube or small test tube with cotton gives constant moisture.

Feeding and Diet

No dietary studies exist for this species. Based on general Myrmecina habits, they likely eat small insects and sweet liquids. Offer tiny prey: fruit flies, pinhead crickets, or minced mealworms. Provide sugar water or honey in small amounts. Remove uneaten food after 2-3 days to avoid mold. Since the colony is tiny, even a single fruit fly is a meal.

Temperature and Seasonal Care

This species comes from high-altitude Xizang, so it likely prefers cooler temperatures than typical room conditions. A starting range of 18-22°C is a reasonable guess, but watch the ants, if they become sluggish or stop brood development, adjust. Do not use a heating cable unless your room is very cold. Diapause may be needed: a winter rest at 10-15°C for 2-3 months could mimic their natural cycle, but this is unconfirmed. Keep records to help future keepers.

Behavior and Handling

These are tiny, timid ants. Workers are not aggressive and are unlikely to sting, they belong to a group that smears venom rather than injecting it. They forage individually and spend most of their time hidden in the nest. Avoid unnecessary disturbance, even opening the nest can stress them. Transferring a colony is tricky due to their size, use gentle methods like connecting tubes. They are not a species for keepers who want active, visible ants.
