Pogonomyrmex colca

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Peru, Caylloma Province at 3425 m elevation in the Yungas cloud forest ecoregion ^[1]. This is a high-altitude, cool environment in the Andes.
• Colony Type: Based on Pogonomyrmex patterns, likely monogyne (single-queen colonies) ^[2].
• Size & Growth:
  • Queen: Size data unavailable, inferred from Pogonomyrmex genus patterns ^[2].
  • Worker: Size data unavailable, inferred from Pogonomyrmex genus patterns ^[2].
  • Colony: Unknown, no data available ^[1].
  • Growth: Unknown, no data available.
  • Development: Unknown, no data available for P. colca. (Development time may vary based on temperature and conditions.)
• Antkeeping:
  • Temperature: Keep cool, around 18-22°C, based on high-altitude origin. Avoid temperatures above 25°C.
  • Humidity: Keep nest substrate consistently moist but not waterlogged, based on cloud forest habitat.
  • Diapause: Unknown, no data available. Based on high-altitude temperate climate, winter diapause may be required, but unconfirmed.
  • Nesting: Y-tong (AAC) or plaster nests work well, based on genus patterns ^[2]. Provide a humidity gradient.
• Behavior: Pogonomyrmex ants are seed-harvesters and have a stinger ^[2]. Workers are active foragers. Escape risk is moderate due to small size.
• Common Issues: overheating can be fatal due to cool temperature requirements, humidity fluctuations may stress the colony, winter dormancy may be needed but is unconfirmed, small size increases escape risk without proper barriers, limited data makes care less predictable

Housing and Nest Setup

Pogonomyrmex colca does well in Y-tong (AAC) nests or plaster formicariums that can hold moisture ^[2]. The key requirement is keeping them cool, their high-altitude origin means overheating is a serious risk. Avoid placing their nest in direct sunlight or near heat sources. A test tube setup works fine for founding colonies. For established colonies, provide a shallow outworld where foragers can search for seeds and protein. Use a standard escape barrier like fluon on the rim of the outworld ^[2].

Feeding and Diet

As seed-harvesters, these ants primarily collect and store seeds ^[2]. Offer a variety of small seeds, grass seeds, millet, and commercial ant seeds work well. They also need protein, so offer small insects like fruit flies, small mealworms, or cricket pieces once or twice a week. Remove uneaten seeds and prey to prevent mold. Sugar water or honey can be offered occasionally but seeds should form the bulk of their diet ^[2].

Temperature and Seasonal Care

This is critical for keeping P. colca. They come from 3425 m elevation in the Peruvian Andes, where temperatures are cool year-round ^[1]. Keep the nest area at 18-22°C, never let it exceed 25°C. A slight temperature gradient allows workers to regulate their body temperature. In winter, reduce temperatures to 10-15°C for 2-3 months to simulate their natural seasonal cycle, but this is unconfirmed.

Humidity Requirements

The Yungas cloud forest is a humid environment, so these ants need consistent moisture ^[1]. Keep the nest substrate damp but not waterlogged. In a Y-tong or plaster nest, check water reservoirs weekly and refill as needed. In test tube setups, ensure the water chamber is adequate but not so large that flooding becomes a risk. A humidity gradient lets ants choose their preferred zone.

Behavior and Handling

Pogonomyrmex ants have a stinger and will use it if they feel threatened ^[2]. Their sting is painful, so handle with care, avoid disturbing the nest unnecessarily. Workers are active foragers that search for seeds and small prey. They are not aggressive toward humans unless provoked, but will defend their nest vigorously. Their small size means they can escape through tiny gaps, so check your barriers regularly ^[2].
