Myopias suwannaphaki

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Borneo (Sabah, Malaysia), found in leaf litter at the edge of secondary forest at 270-300m altitude ^[2][4]
• Colony Type: Unconfirmed, colony structure is unknown for this newly described species
• Size & Growth:
  • Queen: 3.04-3.07mm ^[5]
  • Worker: 2.87-2.94mm ^[5]
  • Colony: Unknown, likely small colonies based on related Myopias species
  • Growth: Moderate
  • Development: Estimated 8-12 weeks at tropical temperatures, direct data unavailable for this species (Ponerinae ants typically have moderate development times. Expect slower growth than faster-moving Formicinae.)
• Antkeeping:
  • Temperature: Keep at 24-28°C, these are tropical rainforest ants from Borneo and need warm, stable conditions ^[2]
  • Humidity: High humidity required, they live in rotting wood in humid forest floor litter. Keep nest substrate consistently moist but not waterlogged ^[2][6]
  • Diapause: Unlikely, being a tropical species from Borneo, they do not require a hibernation period
  • Nesting: Provide rotting wood pieces or a moist plaster nest. They naturally nest in decaying wood on the forest floor, so a naturalistic setup with damp wood works well ^[6]
• Behavior: These are small, cryptic ants that prefer to forage in leaf litter and rotting wood. They have a functional sting but at 3mm size, it's barely perceptible to humans. Workers likely forage in the substrate, hunting small prey. Colonies are probably small and slow-growing. Escape prevention is important due to their tiny size, they can squeeze through very small gaps.
• Common Issues: tiny size makes escape prevention critical, use fine mesh and tight-fitting lids, slow growth can lead to keeper impatience and overfeeding, high humidity requirements can lead to mold if ventilation is poor, newly described species means captive breeding information is limited, wild-caught colonies may have parasites or be stressed from collection

Housing and Nest Setup

Myopias suwannaphaki naturally nests in rotting wood on the forest floor ^[6]. For captivity, a moist plaster nest or naturalistic setup works well. Keep the nest substrate consistently damp, these ants come from humid rainforest environments. You can add small pieces of rotting wood or leaf litter to the outworld to provide foraging enrichment. Because they're tiny (under 3mm), ensure your setup has no gaps larger than 1mm. A test tube setup can work for founding colonies, but you'll need to move them to a more spacious setup as the colony grows. Use a water reservoir to maintain humidity without flooding.

Feeding and Diet

As a Ponerinae species, Myopias suwannaphaki is predatory. They likely hunt small invertebrates in the leaf litter, think springtails, booklice, and tiny beetles. Offer small live prey items like fruit flies, pinhead crickets, or isopods. You can also offer small pieces of insects like bloodworms or mealworm pieces. Sugar sources are unlikely to be accepted, these are strict predators. Feed every 2-3 days, removing any uneaten prey after 24 hours to prevent mold. A varied diet of small live prey will support healthy colony growth. ^[3]

Temperature and Humidity

Keep these ants warm at 24-28°C. They're from tropical Borneo where temperatures are consistently warm year-round. A small heating cable on one side of the nest can create a temperature gradient. Humidity is critical, maintain high relative humidity by keeping the nest substrate moist. Mist the outworld occasionally, but ensure good ventilation to prevent mold. The nest should never dry out completely. A water tube for drinking is also important, though they may get most moisture from their prey. ^[2]

Colony Development

This species was only described in 2020,so captive breeding information is limited ^[3]. Queens are 3.04-3.07mm and workers are 2.87-2.94mm, both very small. Expect slow colony growth typical of Ponerinae. The first workers (nanitics) will be tiny. Colonies likely remain small. Be patient with founding colonies, it may take several months to see the first workers, and a year or more to reach moderate size. Avoid disturbing the queen during founding, vibrations and light can cause her to abandon or eat her brood.

Behavior and Temperament

These are cryptic, ground-dwelling ants that prefer to stay hidden in their nest and foraging areas. They have a sting, but at their tiny size it's unlikely to be felt by humans ^[1]. Workers likely forage in leaf litter, hunting small prey. Colonies are probably not aggressive and will retreat from threats rather than attack. Their small size and cryptic nature make them fascinating to observe but less interactive than larger ant species. They can squeeze through impossibly small gaps due to their minute size.
