Myrmecina maryatiae

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Southeast Asia, Malaysia, Thailand, Indonesia (Borneo/Kalimantan), Singapore. Found in forest litter and under bark in humid tropical and subtropical environments ^[1][2].
• Colony Type: Colony structure is unconfirmed. Based on typical Myrmecina genus patterns, likely single-queen colonies.
• Size & Growth:
  • Queen: Size data unavailable, paratype queen exists but exact measurements not provided in original description ^[1]
  • Worker: 2.37-2.80mm total length ^[1]
  • Colony: Likely small, estimated up to a few hundred workers based on tiny worker size and genus patterns
  • Growth: Moderate, inferred from typical Myrmecina development
  • Development: Estimated 6-10 weeks based on related Myrmecina species and tropical temperature conditions (Development time is not directly studied for this species. Estimates based on genus-level data for small Myrmicinae in tropical conditions.)
• Antkeeping:
  • Temperature: Keep around 24-28°C. These are tropical forest ants from Southeast Asia, so they need warm, stable temperatures. A heating cable on one side of the nest can create a gentle gradient if room temperature is below this range.
  • Humidity: High humidity is essential. They naturally live in forest litter where conditions stay damp. Keep the nest substrate consistently moist but not waterlogged. Mist occasionally and provide a water tube, but ensure good ventilation to prevent mold.
  • Diapause: No, tropical species do not require hibernation. Slight temperature reductions during winter months are tolerated but not necessary.
  • Nesting: They naturally nest under bark and in forest litter. In captivity, they do well in small Y-tong nests, plaster nests, or test tube setups with moist substrate. The key is providing tight, humid chambers scaled to their tiny size. Avoid large, open spaces.
• Behavior: These ants are generally calm and not aggressive. They are tiny and slow-moving, with workers primarily foraging on the forest floor for small prey and honeydew. Their large eyes are unusual for Myrmecina and may indicate enhanced visual capability. Escape prevention is critical, at just 2.4-2.8mm, they can squeeze through very small gaps. Use fine mesh and tight-fitting lids. They do not pose a danger to keepers.
• Common Issues: escape prevention is critical due to their very small size, they can squeeze through gaps that larger ants cannot, high humidity requirements can lead to mold problems if ventilation is poor, slow colony growth may frustrate beginners expecting rapid development, wild-caught colonies may introduce the associated mite (Protoribates myrmecophilus) which is harmless but may concern keepers, they are very small so feeding appropriate-sized prey (fruit flies, pinhead crickets, springtails) is essential

Housing and Nest Setup

Myrmecina maryatiae are tiny ants that need appropriately scaled housing. In the wild, they live in forest litter and under loose bark, where humidity stays consistently high. For captivity, small Y-tong nests, plaster nests, or test tube setups all work well. The key is providing chambers that are appropriately sized, these ants are only 2.4-2.8mm, so they feel secure in compact spaces. Keep the nest substrate or cotton moist but not flooded. A water tube connected to the nest helps maintain humidity. Place the nest in a dark area or cover it with an opaque sleeve, as these forest-floor ants prefer dim conditions. Good ventilation is essential to prevent mold while maintaining humidity, small holes or mesh on the sides work better than sealed enclosures. ^[1][2]

Feeding and Diet

Like most Myrmecina species, M. maryatiae likely feeds on small insects, honeydew, and nectar in the wild. In captivity, offer small protein sources such as fruit flies, tiny crickets, springtails, or small mealworm pieces. They are small enough that standard ant feeders may be too large, pre-kill prey and break it into appropriately sized pieces. A sugar source like honey water or sugar water should be available, though acceptance may vary. Feed protein 2-3 times per week and keep sugar water constantly available. Remove uneaten prey within 24-48 hours to prevent mold. Their association with oribatid mites in the wild suggests they may have complex relationships with other small arthropods, but this doesn't affect their dietary needs in captivity. ^[1][2]

Temperature and Seasonal Care

As tropical ants from Southeast Asia, Myrmecina maryatiae need warm conditions. Keep the nest area at 24-28°C for optimal activity and brood development. Room temperature in most homes may be sufficient if it falls within this range, otherwise use a heating cable on one side of the nest to create a gentle gradient. Place the heating on top of the nest, not underneath, to avoid evaporating moisture too quickly. These ants come from humid tropical forests, so they do not require a true hibernation diapause. However, slight temperature reductions during winter (if your room naturally cools) are likely tolerated. Avoid temperatures below 20°C for extended periods. Monitor colony activity, if workers become sluggish, slightly increase temperature. ^[1]

Behavior and Colony Dynamics

Myrmecina maryatiae workers are small, dark-colored ants that move at a moderate pace. They are not aggressive and do not pose a significant threat to keepers. Colonies likely grow moderately, starting with a single queen (though this is inferred from genus patterns rather than directly observed), the first workers will emerge after several weeks. The colony will gradually expand as the queen continues laying eggs. These ants are foragers that search the outworld for small prey items. Their unusually large eyes for Myrmecina may indicate some visual foraging behavior, though this is not well studied. Expect colony sizes to remain relatively small given the tiny worker size. Handle gently when necessary, they are fragile due to their small size. ^[1]

Handling and Observation Tips

Because Myrmecina maryatiae are so small, observation requires good lighting and potentially magnification. Their dark coloration against lighter backgrounds makes them visible, but their tiny size means you'll need to watch closely to see details. When setting up the outworld (foraging area), keep it simple and easy to clean. Use a shallow dish or container that allows you to observe feeding behavior. These ants are not jumpers or climbers, but their small size means they can escape through incredibly tiny gaps. Double-check all connections, lids, and barriers. When moving colonies or cleaning nests, work gently and quickly to minimize stress. These ants are best enjoyed as a watching species rather than one you handle frequently.
