Pachycondyla procidua

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Northern South America: Peru, French Guiana, Suriname, Brazil, and Colombia (Amazonas) ^[1]. Found in tropical rainforest, including plateau forest and terra firme forest ^[3][4]. Collected at low elevation (50 m) ^[5].
• Colony Type: Not well documented. Colony structure is unknown for this species.
• Size & Growth:
  • Queen: 14 mm total length ^[2]
  • Worker: 13 mm total length ^[2]
  • Colony: Unknown, colony size has not been documented.
  • Growth: Moderate (estimated from typical ponerine development)
  • Development: Estimated 6-10 weeks at tropical temperatures (based on related *Pachycondyla* species, not directly observed) (Development time is inferred, no direct data for this species.)
• Antkeeping:
  • Temperature: Maintain 24-28°C year‑round (tropical habitat). Provide a temperature gradient so workers can choose their preferred spot.
  • Humidity: High humidity (70-80%) similar to tropical rainforest. Keep nest substrate consistently moist but not waterlogged. Provide a water source.
  • Diapause: No, this is a tropical species. Keep warm conditions year‑round.
  • Nesting: In the wild they likely nest in soil or rotting wood on the forest floor ^[2]. In captivity, use a Y‑tong (AAC), plaster, or soil‑filled nest that retains moisture. Provide deep chambers to accommodate their large size.
• Behavior: Workers use a painful sting to subdue prey. They are solitary foragers and moderately defensive of the nest. Primarily nocturnal or crepuscular. They are relatively slow‑moving compared to many ants. Use caution during nest maintenance to avoid stings.
• Common Issues: colonies may fail if kept too dry, humidity is critical for this tropical species, slow colony growth can frustrate beginners who overfeed and cause mold problems, wild‑caught colonies may contain parasites that can devastate captive colonies, potent sting means keepers should use caution during nest maintenance, tropical species are sensitive to temperature drops, avoid cold drafts or air conditioning

Housing and Nest Setup

Because Pachycondyla procidua is large (workers ~13 mm, queens ~14 mm), you need a spacious nest. A Y‑tong (AAC) or plaster formicarium works well, or use a naturalistic setup with a deep soil chamber. Keep the nest material moist but not waterlogged to provide high humidity. Provide a water test tube in the outworld. Use a heating cable on one side of the nest to create a temperature gradient of 24-28 °C, avoid placing it directly on the nest to prevent drying. Apply a fluon barrier on the rim of the outworld to prevent escapes (their size makes standard barriers sufficient) ^[2].

Feeding and Diet

As a predatory ponerine, P. procidua needs a protein‑rich diet. Offer live insects like crickets, mealworms, and fruit flies appropriate to colony size. Workers are solitary hunters, they don’t recruit nestmates to large prey. Feed 2-3 times per week and remove leftover prey after 24 hours to prevent mold. You can also offer sugar water occasionally, though protein should be the staple. Provide a constant water source.

Temperature and Seasonal Care

Keep the colony warm year‑round at 24-28 °C. Use a heating cable on top of the nest to create a gradient. Room temperature may be adequate if it stays above 24 °C. This tropical species does not require diapause, do not cool it in winter. Avoid placing the nest near cold windows, air conditioning vents, or drafty areas, sudden temperature drops can cause stress or death.

Behavior and Handling

Workers have a potent sting and will defend the nest if provoked. They are solitary foragers and tend to be slow‑moving, which makes them easy to observe but less efficient at catching fast prey. They are primarily active at night or during twilight hours. While not medically dangerous to healthy adults, their sting is painful and may cause local swelling. Use tools or gloves during maintenance to avoid being stung.
