Pogonomyrmex spinolae

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Central and Southern Chile, specifically the dry puna and Andean steppe ecoregions ^[1]. These areas feature cool temperatures and low rainfall.
• Colony Type: Single-queen colonies are likely based on typical Pogonomyrmex patterns, though direct studies for this species are lacking.
• Size & Growth:
  • Queen: ~6-9 mm, inferred from Pogonomyrmex genus ^[1]
  • Worker: ~5-8 mm, inferred from Pogonomyrmex genus ^[1]
  • Colony: Up to several thousand workers ^[1]
  • Growth: Moderate
  • Development: 8-12 weeks at optimal temperatures ^[1] (Development slows in cooler conditions.)
• Antkeeping:
  • Temperature: Keep stable in the low-to-mid 20s°C. They come from cool mountain regions, so avoid heat spikes above 28°C.
  • Humidity: Provide a mostly dry nest with one small moist area. Their natural habitat is arid, so damp nests will cause mold and stress.
  • Diapause: Yes, roughly 3 to 4 months during the cooler months. Mimic their Andean winter to keep the colony healthy.
  • Nesting: Plaster nests, soil nests, or 3D-printed setups work best. Avoid overly humid environments.
• Behavior: Defensive and will sting if threatened. They forage for seeds and store them in the nest. Medium size means moderate escape risk, so use fine mesh barriers.
• Common Issues: colonies fail if kept too humid, they prefer dry conditions, slow growth can tempt keepers to overfeed, stick to a seed-heavy diet, stinging makes handling difficult, move slowly and avoid direct nest contact, skipping winter rest causes colony decline, they need seasonal cooling, wild colonies may carry parasites, quarantine new queens

Housing and Nest Setup

Pogonomyrmex spinolae thrives in dry environments ^[1]. Use plaster nests, soil nests, or 3D-printed setups instead of acrylic. They prefer snug chambers, so avoid oversized nests. Provide a shallow water dish for drinking and a separate outworld for foraging. Apply fluon to test tube rims and cover ventilation holes with fine mesh to prevent escapes ^[2].

Feeding and Diet

These ants harvest seeds as their main food source ^[1]. Offer grass seeds, millet, and small bird seed constantly in the foraging area. Add protein like small insects 2 to 3 times per week. They also take sugar water occasionally. Remove uneaten seeds to prevent mold ^[2].

Temperature and Seasonal Care

Keep these ants in the low-to-mid 20s°C ^[1]. They come from cool Andean regions, so avoid heat spikes above 28°C. Provide a winter rest period of roughly 3 to 4 months at cooler temperatures around 10 to 15°C. This seasonal cooling mimics their natural habitat and keeps the colony healthy ^[1].

Defense and Sting

Pogonomyrmex spinolae has a functional sting and will use it when threatened. Their sting causes localized pain and swelling, which is typical for the genus. Move slowly and avoid disturbing the nest directly. If you get stung, wash the area and apply ice for relief ^[2].

Growth and Development

Colony growth moves at a moderate pace ^[1]. Expect 8 to 12 weeks until the first workers emerge ^[1]. Founding behavior is unconfirmed, so monitor the queen closely during the early stages. A healthy colony expands steadily over several years ^[2].
