Myrmica tamarae

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Erzurum Province, Turkey (East Anatolia), high mountain meadows at 2250-2800m elevation in the Palandoken mountain range ^[1][2]. The cold, temperate alpine environment has distinct seasons.
• Colony Type: Likely single-queen colonies based on typical excelsa-complex patterns, inferred from genus
• Size & Growth:
  • Queen: size data unavailable, inferred from Myrmica genus (~5-8mm)
  • Worker: size data unavailable, inferred from Myrmica genus (~4-6mm)
  • Colony: Likely up to several hundred workers, inferred from Myrmica genus patterns
  • Growth: Moderate, slower than lowland species due to cold-adapted biology
  • Development: Estimated 8-12 weeks at optimal temperature, inferred from related Myrmica species (Development is likely slower than typical Myrmica due to cold-adapted nature)
• Antkeeping:
  • Temperature: Keep cool, aim for 15-22°C range. These high-altitude ants prefer cooler conditions than most Myrmica. Room temperature (18-22°C) is typically suitable, but avoid overheating above 25°C.
  • Humidity: Moderate humidity (50-70%). Mountain meadow habitat suggests they prefer well-ventilated conditions with damp but not waterlogged substrate. Allow the nest to partially dry between waterings.
  • Diapause: Yes, mandatory winter dormancy period of 3-4 months at 5-10°C. This cold-adapted species requires proper hibernation to trigger reproductive cycles and maintain colony health.
  • Nesting: Y-tong (AAC) or test tube setups work well. Provide a moisture reservoir but ensure good ventilation. The species likely nests in soil or under stones in nature, captive colonies do well with compact chambers scaled to their worker size.
• Behavior: Workers are moderately active and typically non-aggressive toward keepers. They show typical Myrmica foraging behavior, actively searching for small prey and sugar sources. Escape risk is moderate, standard barrier methods (Fluon, fine mesh) are sufficient. Workers have a functional stinger but rarely use it unless provoked. They are diurnal foragers, most active during cooler parts of the day in captivity.
• Common Issues: cold stress from overheating, keep them cool, never above 25°C, colonies failing to produce alates without proper hibernation cycles, slow growth can lead to overfeeding and mold problems in founding colonies, limited genetic diversity in captive stocks due to restricted wild distribution, difficulty obtaining this species as it's rarely available in the antkeeping trade

Housing and Nest Setup

Myrmica tamarae does well in standard antkeeping setups. For founding colonies, a test tube setup with a water reservoir works perfectly, the queen seals herself in and raises her first brood in the humid microclimate of the tube. Once the colony reaches 15-20 workers, you can move them to a Y-tong (AAC) nest or a naturalistic setup. Because they come from well-ventilated mountain meadows, ensure your setup has adequate air flow. Avoid fully sealed nests without ventilation. A moisture reservoir connected to the nest helps maintain humidity, but allow some drying time between waterings to prevent mold. Keep the nest area relatively cool, these ants do not tolerate heat well.

Feeding and Diet

Like most Myrmica species, M. tamarae is omnivorous with a preference for protein. Offer small live prey such as fruit flies, pinhead crickets, or mealworms, appropriately sized to the worker size. They also accept sugar sources like honey water or sugar water, though protein should form the majority of their diet. Feed small amounts 2-3 times per week for established colonies, removing any uneaten prey after 24 hours to prevent mold. During founding, the queen will not eat, she relies on stored fat reserves until her first workers emerge. Once workers are present, they will forage for food outside the nest.

Temperature and Seasonal Care

This is the most critical aspect of keeping M. tamarae successfully. Being a high-altitude species from the Turkish mountains, they require cool conditions year-round. Keep the nest area between 15-22°C, with room temperature typically being ideal. Never use heating mats or cables with this species, overheating is a common killer. During summer months, ensure they are not in direct sunlight or in rooms that get warm. In winter, you must provide a proper diapause (hibernation) period of 3-4 months at 5-10°C. Place the colony in an unheated garage, basement, or refrigerator (not freezer) during winter. This hibernation period is essential for triggering reproductive cycles, colonies that are kept warm year-round often fail to produce alates (reproductives).

Colony Development and Growth

Myrmica tamarae colonies grow moderately, with the queen laying eggs throughout the warm season. The first workers (nanitics) are typically smaller than mature workers and appear 8-12 weeks after the eggs are laid, though exact timing depends on temperature. Cooler conditions will slow development significantly. Colonies likely reach several hundred workers over several years. Mature colonies produce alates (reproductives) annually if properly hibernated. The colony structure is likely single-queen (monogyne), with the queen being the sole egg-layer.

Behavior and Handling

Workers of M. tamarae are active foragers with typical Myrmica behavior, they search systematically for food and communicate discoveries to nestmates. They are not particularly aggressive and rarely sting unless directly threatened. When threatened, they may use their stinger, but the sting is mild for humans. They are good escape artists for their size, so ensure your setup has proper barriers. Fluon applied to the edges of the outworld works well. These ants are diurnal, with peak activity during cooler parts of the day. They do not exhibit unusual behaviors like slave-making or temporary parasitism, they are straightforward, native Myrmica that establish and maintain simple single-queen colonies.
