Myrmica dshungarica - "Dzungarian Ant"
Myrmica dshungarica is a fascinating ant species belonging to the Myrmicinae subfamily. They are primarily found in the mountain regions of Central Asia, specifically in areas of Kazakhstan, Kyrgyzstan, Uzbekistan, and Tajikistan. These ants are characterized by their robust bodies and typically reddish-brown coloration, though specific sizes for queens and workers of this exact species are not readily available in general sources. They are known for inhabiting wet or damp environments, often near rivers and streams, and can also be found in subalpine meadows under stones. Distinguishing them from other Myrmica species can be challenging, but they are noted for a shorter, higher petiole and a distinctly convex head side. Like other Myrmica, they possess a sting.

- Worker: Not specified
- Colony: Medium (thousands). Medium growth.
- Antkeeping:
- Temperature: Maintain a temperature range of 20-25°C. Avoid excessively high temperatures..
- Humidity: High humidity (70-90%) is crucial due to their hygrophilous nature. Ensure a consistently moist environment..
- Diapause: Required. 3-4 months at 5-12°C.
- Nesting: Prefers naturalistic setups such as soil nests, often under stones, or highly humid artificial nests with adequate hydration. Acrylic or Ytong nests with large hydration reservoirs are suitable..
- Behavior: Medium (towards handler, food or other ants) aggressiveness.
- Common Issues: Humidity fluctuations, Colony stalling due to insufficient feeding during founding, Mold in nest from excessive humidity without ventilation, Queen stress during improper diapause.
Myrmica dshungarica, like many Myrmica species, has specific humidity requirements. Coming from moist mountain habitats, consistently high humidity in their formicarium is non-negotiable for their well-being. Without proper moisture, the brood can fail to develop, and the colony's overall health will decline rapidly. Consider using nests with large water reservoirs or regularly hydrating natural substrate setups to keep the environment damp, mimicking their natural preferences.
These ants are known to be quite active foragers and can exhibit aggressive behavior, especially when their nest is disturbed. While their sting is not medically significant for most people, it can be painful and cause temporary irritation. Handlers should exercise caution and avoid direct contact with the ants. Providing an escape-proof outworld with adequate ventilation is crucial for both the ants' well-being and the keeper's safety.
As a semi-claustral species, Myrmica dshungarica queens will benefit from small offerings of protein and sugar water during the founding stage. Unlike fully claustral queens, they don't rely solely on their fat reserves and need external food sources to raise their first nanitics. This can be a bit more hands-on for beginners, but it's a rewarding process to see the queen actively forage and support her initial brood.
Diapause is an essential part of the Myrmica dshungarica life cycle. A cool, consistent diapause period is critical for the queen's health and the colony's long-term growth and reproductive success. Failure to provide a proper hibernation can lead to reduced egg-laying, stressed queens, and potentially colony failure. Ensure temperatures are lowered gradually and maintained steadily throughout the diapause period.
Frequently Asked Questions
What kind of nest is best for Myrmica dshungarica?
For Myrmica dshungarica, a nest that can maintain consistently high humidity is crucial. Options like Ytong nests with large hydration systems, acrylic nests with deep water reservoirs, or naturalistic setups with moist soil or loam are highly recommended. They thrive in damp conditions, so avoiding quick-drying setups is key for their health and brood development.
Do Myrmica dshungarica sting?
Yes, Myrmica dshungarica workers do possess a sting, similar to other Myrmica species. While generally not dangerous for humans, a sting can be quite painful and cause localized irritation. It's always best to handle them with care and avoid direct contact with your skin.
What do I feed a Myrmica dshungarica colony?
These ants are omnivores and will readily accept a variety of foods. Their diet should consist of sweet liquids like sugar water or honey water, along with a consistent supply of protein such as small feeder insects (e.g., fruit flies, small mealworms, roaches). Since they are semi-claustral, even founding queens will benefit from tiny amounts of food.
Is Myrmica dshungarica hard to keep?
Myrmica dshungarica is rated as 'Medium' difficulty. While not as challenging as some exotic species, they require consistent high humidity and proper diapause, which can be overlooked by new antkeepers. Their semi-claustral founding also means queens need to be fed, adding a bit more hands-on care compared to fully claustral species.
How large do Myrmica dshungarica colonies get?
Myrmica dshungarica colonies are estimated to reach sizes in the thousands. While they won't form supercolonies like some highly prolific species, a well-cared-for colony can grow into a sizable and active community, offering great observation opportunities.
Do Myrmica dshungarica need hibernation?
Absolutely. Myrmica dshungarica requires a diapause period, typically lasting 3 to 4 months, at cooler temperatures between 5-12°C. This mimics their natural seasonal cycles in their mountainous habitats and is vital for the queen's longevity and the colony's health and future egg production.
What is the growth rate of a Myrmica dshungarica colony?
Myrmica dshungarica colonies generally exhibit a 'Medium' growth rate. While they might start slowly during the semi-claustral founding phase, once the first workers arrive and foraging begins, the colony can pick up pace steadily, especially with multiple queens.
Can Myrmica dshungarica queens be kept together (pleometrosis)?
Yes, Myrmica dshungarica is a polygynous species, meaning multiple queens can co-exist and cooperate in founding a new colony (pleometrosis). This can lead to a faster initial colony boost, though careful management of resources and space is still advised.
What kind of substrate is best for their outworld?
For their outworld, a naturalistic substrate like sand, loam, or fine gravel works well. Providing some small stones or pieces of wood can also give them opportunities to explore and forage in a more natural setting, reflecting their wild tendencies to nest under objects.
How aggressive are Myrmica dshungarica?
Myrmica dshungarica are considered to have a 'Medium' level of aggression. They can be quite defensive of their nest and brood, especially if disturbed. While they might attack feeder insects or rival ants with vigor, they typically won't bother keepers unless provoked.
How long does it take for Myrmica dshungarica eggs to become workers?
The full development from egg to adult worker for Myrmica dshungarica typically takes between 6 to 9 weeks, depending on environmental factors like temperature and food availability. Maintaining optimal conditions will help ensure a healthy and consistent brood cycle.
