Pogonomyrmex catanlilensis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to Argentina, specifically the Neuquén region in Southern Andean and Patagonian steppe ecoregions, at elevations of 790-1520 meters ^[1].
• Colony Type: Unconfirmed, research does not specify queen number or social structure.
• Size & Growth:
  • Queen: size data unavailable, research provides head measurements but not total body length ^[1]
  • Worker: size data unavailable, research provides head measurements but not total body length ^[1]
  • Colony: Up to approximately 2000 workers ^[1]
  • Growth: Moderate, inferred from typical seed-harvester ant patterns
  • Development: Estimated 6-10 weeks based on typical Pogonomyrmex development patterns (Development time is inferred from genus-level data, as species-specific data is not available. Temperature affects speed.)
• Antkeeping:
  • Temperature: Keep at 24-28°C during active season, with a thermal gradient for self-regulation
  • Humidity: Low to moderate, as they inhabit dry steppe regions, keep nest substrate mostly dry with occasional moisture zones ^[1]
  • Diapause: Yes, likely required based on temperate habitat and seasonal sexual production
  • Nesting: Y-tong or plaster nests with dry substrate, mimicking their natural mound-building behavior ^[1]
• Behavior: Workers are solitary foragers that collect seeds and defend the nest with a potent sting ^[1]. Escape risk is moderate due to their active foraging nature.
• Common Issues: colonies may fail if kept too humid, these are steppe ants that prefer drier conditions ^[1], their potent sting makes handling risky, use caution when servicing the nest ^[1], slow founding phase if queen is disturbed, queens need darkness and quiet during founding, seed storage can mold if humidity is too high, winter dormancy is likely required but timing must be correct to avoid colony loss

Housing and Nest Setup

Use Y-tong or plaster nests with a dry substrate to mimic their natural steppe habitat ^[1]. Provide compact chambers and a granary area for seed storage, as workers collect seeds ^[1]. The outworld should have easy access to food and secure barriers to prevent escapes, since workers are active foragers ^[1].

Feeding and Diet

Offer seeds like millet, chia, and small sunflower seeds as their primary diet ^[1]. Provide protein from small insects twice weekly and sugar sources like honey water ^[1]. During founding, queens do not need protein, they rely on fat reserves.

Temperature and Seasonal Care

Maintain 24-28°C during active season with a thermal gradient. For diapause, reduce temperatures to 10-15°C for 2-3 months in winter, based on their temperate habitat. Avoid extreme heat above 30°C. ^[1]

Behavior and Defense

Workers forage solitarily and will sting if threatened ^[1]. Move slowly around the nest to minimize defensive responses. Escape risk is moderate, ensure all connections are secure ^[1].

Colony Development

Colonies reach up to 2000 workers ^[1]. Growth is moderate, with first workers emerging in 6-10 weeks. Founding takes several months as queens raise brood alone.
