Pogonomyrmex maulensis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Central Chile (Maule region, Talca Province) at elevations of 1950-2175m in the Valdivian temperate forests ecoregion ^[1].
• Colony Type: Unconfirmed, the research does not specify queen number, but based on Pogonomyrmex genus patterns, likely monogyne.
• Size & Growth:
  • Queen: Size data unavailable, body length measurements not provided in research.
  • Worker: Size data unavailable, body length measurements not provided in research.
  • Colony: Up to 3000 workers ^[1]
  • Growth: Moderate, inferred from genus patterns
  • Development: Estimated 6-10 weeks based on typical Pogonomyrmex development patterns (Development time inferred from genus-level data, specific measurements unavailable for this species)
• Antkeeping:
  • Temperature: Keep at roughly 20-26°C with a gradient. Based on high-elevation habitat, they prefer cooler conditions.
  • Humidity: Keep substrate moderately moist but allow drying between waterings. Provide a water tube but avoid waterlogging.
  • Diapause: Yes, likely requires winter diapause of 2-3 months at 10-15°C, based on high-elevation origin.
  • Nesting: Y-tong (AAC) nests work well. Provide a connection to an outworld for foraging.
• Behavior: These ants are defensive and will sting if threatened, characteristic of the Pogonomyrmex genus. Escape risk is moderate due to their size.
• Common Issues: stinging, Pogonomyrmex ants have painful stings and may attack if the nest is disturbed., colonies can reach up to 3000 workers requiring larger setups as they mature ^[1]., high-elevation origin means they may not tolerate prolonged heat., seed-harvesting behavior requires proper substrate or feeding dishes to prevent mold from scattered seeds., winter dormancy is likely required and must be managed properly to avoid colony losses.

Nest Preferences and Housing

Pogonomyrmex maulensis does well in standard formicarium setups. Y-tong (AAC) nests are ideal because they provide the dark, moderately humid chambers these ants prefer. The key is matching chamber size to the colony, start with smaller chambers when the colony is small and expand as it grows. Since colonies can reach up to 3000 workers, plan for a spacious setup by the time the colony matures. Connect the nest to an outworld using tubing, and ensure the outworld has a secure lid as these ants can climb smooth surfaces reasonably well. A thin layer of substrate in the outworld allows them to engage in natural seed-harvesting behavior. ^[1]

Feeding and Diet

As seed-harvesters, Pogonomyrmex maulensis collects and stores seeds as their primary food source ^[1]. In captivity, offer a variety of small seeds, millet, sesame, and cracked sunflower seeds work well. They will crack seeds open and consume the nutritious insides. However, they also benefit from protein supplementation. Offer small insects like fruit flies, small crickets, or mealworms periodically. Sugar water or honey can be offered occasionally but is not a primary dietary need for this granivorous species. Remove uneaten seeds and insects promptly to prevent mold, which can be harmful to the colony.

Temperature and Seasonal Care

This species comes from high elevations (1950-2175m) in the Chilean Andes, so they prefer cooler conditions than many other Pogonomyrmex species ^[1]. Keep the nest area at roughly 20-26°C, with room temperature typically being suitable. Avoid prolonged exposure to temperatures above 30°C. A heating cable on one side of the nest can create a temperature gradient, allowing workers to choose their preferred zone. During winter, provide a diapause period of 2-3 months at 10-15°C. This mimics their natural seasonal cycle in the temperate Andean region. Reduce feeding during diapause and keep the nest slightly cooler but not cold.

Behavior and Defense

Pogonomyrmex maulensis has a functional stinger and will use it when defending the nest. Their sting is painful, this is characteristic of the Pogonomyrmex genus. When working with this species, move slowly and avoid vibrations or sudden disturbances near the nest. If the colony feels threatened, they may swarm in defense. Use appropriate escape prevention like fluon barriers on the rim of the outworld. Workers are active foragers, primarily during cooler parts of the day in captivity, this matches their high-elevation origin where temperatures are moderate.
