Myrmecina poringensis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Myrmecina poringensis comes from the rainforests of Borneo, specifically Sabah, Malaysia, where it was collected at Poring Hot Springs at elevations of 500-600m ^[1]. This is a tropical humid forest habitat.
• Colony Type: Unconfirmed, no specific colony structure data exists for this species.
• Size & Growth:
  • Queen: Size data unavailable, queen caste has not been described
  • Worker: 2.34-2.45mm ^[1]
  • Colony: Unknown, no colony size data exists for this species
  • Growth: Unknown
  • Development: Unknown, no development data exists for this species (No direct development data exists for this species.)
• Antkeeping:
  • Temperature: Keep around 24-28°C, these are tropical forest ants that need warmth. A gentle gradient allowing them to move between warmer and cooler areas is ideal.
  • Humidity: High humidity required, think damp rainforest floor. Keep the nest substrate consistently moist but not waterlogged. Provide a water source.
  • Diapause: Unlikely, being a tropical species from Borneo, they probably do not require a hibernation period. Keep them warm year-round.
  • Nesting: Small test tube setups or Y-tong nests with tight chambers work well. These tiny ants need appropriately scaled housing with small chambers and narrow passages. A naturalistic setup with moist soil and hiding spots mimics their natural forest floor habitat.
• Behavior: These are likely peaceful, slow-moving ants. Their tiny size means their stingers cannot penetrate human skin. Foraging is probably slow and deliberate. Escape prevention is critical because of their very small size, they can squeeze through the tiniest gaps. Use fine mesh and tight-fitting lids.
• Common Issues: escape prevention is critical, their tiny 2.4mm size means they can slip through standard barrier setups, no biology data exists, keepers are essentially pioneering captive care for this species, slow growth means colonies develop gradually and require patience, high humidity needs can lead to mold problems if ventilation is inadequate, test tube setups must be properly sized, chambers too large can stress small colonies

Housing and Nest Setup

Because Myrmecina poringensis workers are only about 2.4mm, housing must be appropriately scaled. Standard test tubes work but ensure the cotton is packed tightly, these tiny ants can push through gaps that larger ants cannot. Y-tong nests designed for small species or small acrylic nests with tight chambers are ideal. The nest material should retain moisture well, plaster or acrylic with a water reservoir works better than wooden setups. Add some substrate depth if using a naturalistic setup so they can create their own tunnels. Because they're from humid rainforest environments, the nest should maintain high humidity while still allowing some ventilation to prevent mold. ^[1]

Feeding and Diet

No specific feeding observations exist for this species, but Myrmecina ants generally are omnivorous. Offer sugar water or honey as an energy source, these tiny ants will likely accept sweet liquids readily. For protein, offer small live prey like fruit flies, pinhead crickets, or micro worms. Given their tiny size, prey items should be appropriately small. Feed every 2-3 days and remove uneaten prey to prevent mold. A varied diet helps, but avoid overfeeding as these small colonies cannot consume large quantities.

Temperature and Humidity

Being from tropical Borneo, these ants need warm and humid conditions. Maintain temperatures between 24-28°C. A heating cable on one side of the nest creates a gradient they can regulate themselves. Humidity should be high, aim for 70-80% relative humidity in the nest area. The substrate should feel consistently damp but never waterlogged. Mist the outworld occasionally and use a water source like a test tube water feeder. Poor humidity leads to desiccation and colony loss. Too much ventilation causes drying, but too little causes mold, balance is key. ^[1]

Colony Establishment

Since this species was only described in 2020,no established captive breeding protocols exist. If you obtain a founding queen, provide a small test tube with water reservoir, keep it dark and undisturbed, and maintain warm, humid conditions. The founding chamber should be small to help her feel secure. Expect a wait of several months before first workers appear. Given the complete lack of species-specific biology data, keepers are essentially pioneering captive husbandry for Myrmecina poringensis. Document your observations carefully, they could be valuable for future keepers. ^[1]

Defense Mechanism

Myrmecina poringensis belongs to the subfamily Myrmicinae and tribe Crematogastrini. Members of this tribe have a modified, flattened stinger used to wipe or smear venom onto enemies rather than piercing flesh. However, given the tiny size of this species, their ability to penetrate human skin is unlikely.
