Pogonomyrmex guatemaltecus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Guatemala, El Salvador, and southern Mexico (Oaxaca and Chiapas states). Found at elevations around 285m in tropical dry forest habitats ^[2][1]. Type locality is La Fragua, Zacapa, Guatemala ^[3].
• Colony Type: Single-queen colonies with one founding queen that establishes a permanent nest.
• Size & Growth:
  • Queen: ~6-10mm, inferred from Pogonomyrmex genus (size data unavailable in primary sources)
  • Worker: ~5-9mm, inferred from Pogonomyrmex genus (size data unavailable in primary sources)
  • Colony: size data unavailable
  • Growth: Moderate
  • Development: Unknown. Development time is unconfirmed. (Development time is unconfirmed. Keep temperatures warm and stable.)
• Antkeeping:
  • Temperature: Keep warm and stable, roughly low-to-mid 20s°C. Exact needs are unclear.
  • Humidity: Provide a humidity gradient, mostly dry nest chamber with one small moist area.
  • Diapause: Unknown. Diapause requirements are unconfirmed.
  • Nesting: Y-tong (AAC), plaster, soil nests, or 3D-printed nests work well. They prefer dry, stable conditions.
• Behavior: Workers are active foragers that collect and store seeds. They defend their colony vigorously. Like other Myrmicinae, they possess a functional sting. Escape prevention is standard for medium-sized ants.
• Common Issues: mold from excessive moisture, keep nesting area dry, cold temperatures causing sluggish behavior or colony decline, stings can be painful, handle with care and use proper protection, overfeeding leading to mold in the nest, remove uneaten seeds, colonies may be slow to establish initially, patience needed

Nest Preferences and Housing

You can house Pogonomyrmex guatemaltecus in Y-tong (AAC), plaster, soil nests, or 3D-printed setups. They build underground chambers very similar to North American Pogonomyrmex species ^[3]. Keep the nest relatively dry. Provide a small water tube for drinking, but avoid soaking the substrate. Transfer the colony to a larger nest once you see steady worker production. Standard escape prevention works fine for this size.

Feeding and Diet

These ants store and eat seeds ^[3]. Offer a variety of small seeds like millet, grass seeds, or commercial bird seed mixes. They also need protein. Feed them small insects like fruit flies or pinhead crickets. You can offer sugar water occasionally, but seeds are their main food. Remove any moldy seeds promptly to keep the nest clean.

Temperature and Heating

Keep the nest area warm. Exact temperature needs are unclear, but aim for the low-to-mid 20s°C. A heating cable on one side creates a gradient you can use to adjust conditions. Avoid cold drafts. Since they come from tropical Central America, consistent warmth works best.

Behavior and Temperament

Workers are active foragers that leave the nest to search for seeds. They defend their colony vigorously. Like other Myrmicinae, they have a functional sting that can be painful. Handle established colonies with care. Wear gloves and eye protection when working with them. They are diurnal and most active during daylight.

Colony Founding

Founding behavior is unconfirmed. You should keep the founding queen undisturbed in a dark, quiet location. Do not guess about claustral or semi-claustral methods. Wait for the first workers to emerge before offering food or checking on them.
