Myopias sakaeratensis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Northeastern Thailand, specifically Nakhon Ratchasima and Chaiyaphum Provinces. Found in lowland dry evergreen forest and dry dipterocarp forest at elevations around 270m. Nests in rotting logs on the forest floor ^[1].
• Colony Type: Unconfirmed colony structure. Like most Ponerinae, likely forms single-queen colonies, but this has not been directly studied.
• Size & Growth:
  • Queen: Unknown, queen has not been described in scientific literature ^[1]
  • Worker: 6.55-6.94 mm total length ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown, likely moderate based on typical Ponerine patterns
  • Development: Unconfirmed, no direct development data exists. Based on related Ponerine ants, estimate 6-10 weeks at optimal temperature. (Development timeline is unconfirmed. Related Ponerine species typically take 6-10 weeks from egg to worker at tropical temperatures.)
• Antkeeping:
  • Temperature: Keep around 24-28°C. Being from tropical Thailand, they need warm conditions. A heating cable on one side of the nest creates a gradient allowing them to regulate temperature.
  • Humidity: Moderate humidity around 60-75%. Their natural habitat is dry evergreen forest, so avoid overly wet conditions. Keep the nest substrate slightly moist but allow some drying between waterings.
  • Diapause: Unlikely required. As a tropical species from Thailand, they probably do not need a true hibernation. However, they may slow down during cooler months, reduce feeding and slightly lower temperatures (around 20-22°C) during winter if the colony shows reduced activity.
  • Nesting: Provide a naturalistic setup with rotting wood pieces or a Y-tong/plaster nest with chambers scaled to their medium size. They naturally nest in rotting logs, so include some wood material in the setup. Ensure the nest has some dry areas as well as moist zones.
• Behavior: These ants are predatory hunters, typical of the Ponerinae subfamily. They hunt small invertebrates and arthropods. They have a well-developed stinger and will use it defensively if threatened, though they are not particularly aggressive toward keepers. Workers are medium-sized and relatively robust. Escape prevention should be good but not as critical as for tiny ants, standard formicarium barriers should work well. They are likely diurnal and most active during warmer hours.
• Common Issues: no development data makes timing first workers uncertain, patience is required, tropical species may not tolerate cool temperatures, keep warm year-round, predatory diet requires live prey, cannot survive on sugar alone, limited research means care is largely inferred from genus patterns, wild-caught colonies may carry parasites that can cause problems in captivity

Housing and Nest Setup

Myopias sakaeratensis naturally nests in rotting wood on the forest floor, so a naturalistic setup works well. Include pieces of rotting wood, dead leaves, or bark in the outworld to mimic their natural environment. For the nest itself, a Y-tong or plaster nest with medium-sized chambers works well. The chambers should be sized appropriately for medium ants, not too tight, but with passages narrow enough that workers feel secure. Provide a water reservoir connected to the nest for humidity, but avoid flooding. A small outworld with natural décor also encourages natural foraging behavior. Standard escape prevention (fluon on rim edges) is sufficient for their medium size, they are not escape artists like tiny ants. ^[1]

Feeding and Diet

As a Ponerine ant, Myopias sakaeratensis is predatory and needs live protein prey to survive. Offer small live insects like fruit flies, pinhead crickets, mealworms, and other appropriately-sized arthropods. They likely accept dead prey as well, especially once a colony is established, but live prey should form the basis of their diet. Sugar sources like honey water or sugar water may be accepted, but Ponerines are not typically heavy honeydew consumers like some other subfamilies. Feed every 2-3 days, adjusting based on colony size and consumption. Remove uneaten prey after 24-48 hours to prevent mold. A varied diet helps ensure proper nutrition.

Temperature and Seasonal Care

Being from tropical Thailand, these ants need warm conditions year-round. Keep the nest area at 24-28°C during the active season. A heating cable placed on top of the nest (never underneath where it can dry out the substrate) creates a temperature gradient. Room temperature may be sufficient if your home stays in this range, otherwise use a small heat mat or cable. Unlike temperate species, they likely do not require true hibernation, but may slow slightly during cooler periods. If your colony shows reduced activity in winter, you can reduce temperatures to around 20-22°C and reduce feeding frequency. Do not allow temperatures to drop below 18°C for extended periods.

Behavior and Handling

Myopias sakaeratensis has a well-developed stinger and will use it defensively if threatened. However, they are not typically aggressive toward keepers and will usually retreat rather than attack. The sting is likely painful but not dangerous to healthy humans. When working with the colony, go slowly and avoid sudden movements. If you need to move or disturb the nest, do so carefully. Workers are medium-sized and relatively robust, they can handle some disturbance but prefer stability. They are likely diurnal, being most active during daylight hours when their natural prey is also active.

Colony Development and Expectations

This is a recently described species (2018) with very limited research, so colony development expectations are based on typical Ponerine patterns rather than direct observation. Expect slow to moderate growth, Ponerine colonies typically develop more slowly than many common ant species. The first workers (nanitics) may take 6-10 weeks or longer to emerge, depending on temperature and feeding. Colonies likely reach several hundred workers at maturity, though exact maximum size is unknown. Patience is essential with this species, do not overfeed or disturb the founding queen excessively. Once established, colonies should grow steadily with proper care and feeding.
