Pheidole ademonia

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Amazon rainforest of Peru and Ecuador, in terra firme forests. Type locality is Cuzco Amazónico, Peru, and also recorded from Yasuni National Park, Ecuador ^[1][2][3].
• Colony Type: Colony structure is unconfirmed. Based on Pheidole patterns, likely monogyne (single queen), but this specific species has not been studied.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Pheidole genus patterns
  • Worker: Size data unavailable for total length, head width measurements are not used as body size ^[1]
  • Colony: Unknown, likely up to several hundred workers based on typical Pheidole colonies
  • Growth: Moderate, based on typical Pheidole development patterns
  • Development: Estimated 6-8 weeks at tropical temperatures, based on genus-level patterns (Development time is inferred from related tropical Pheidole species. Warmer temperatures may speed up development.)
• Antkeeping:
  • Temperature: Keep warm and stable, roughly 24-28°C, as inferred from tropical habitat
  • Humidity: Provide a humidity gradient, mostly dry nest chamber with one small moist area, as they have low flood tolerance ^[2]
  • Diapause: No, tropical species do not require hibernation
  • Nesting: Twig-nesting species. Use Y-tong nests with narrow chambers or test tube setups ^[2][1]
• Behavior: These ants are active foragers and will defend their nest. Escape prevention is critical due to their small size ^[1].
• Common Issues: escape prevention is critical due to their tiny size, minors can slip through standard barrier gaps, tropical species are sensitive to temperature drops, keep warm and avoid cold drafts, low flood tolerance means they need well-drained nests that don't retain excess water, slow colony growth can frustrate beginners, Pheidole colonies take time to establish, wild-caught colonies may have parasites that can devastate captive colonies

Nest Preferences and Housing

Pheidole ademonia is a twig-nesting species that naturally nests in small cavities beneath bark on rotten logs and in soil ^[2][1]. In captivity, they do well in Y-tong nests with chambers scaled to their size, small test tube setups with cotton stoppers, or naturalistic setups with rotting wood pieces. Provide tight, enclosed spaces, avoid large, open formicaria. For founding colonies, a test tube setup with a water reservoir works well. Ensure excellent escape prevention as minors are extremely small.

Feeding and Diet

Pheidole ants are omnivores with a preference for seeds and protein. Offer a varied diet including small seeds, protein sources like small crickets or fruit flies, and sugar sources like honey water. Major workers have enlarged heads for seed processing. Feed protein 2-3 times per week with constant access to sugar water. Remove uneaten food within 24-48 hours to prevent mold. ^[1]

Temperature and Seasonal Care

As a tropical species, maintain warm conditions around 24-28°C. Avoid temperature drops below 20°C. No hibernation is required, keep them warm year-round. Use a heating cable on one side of the nest to create a gentle gradient, but ensure an unheated area for temperature regulation.

Behavior and Colony Dynamics

This species exhibits distinct major and minor worker castes. Major workers handle seed processing and defense, while minors forage and care for brood. Colonies are likely led by a single queen. Workers are not highly aggressive but will defend the nest. Colony growth is gradual, with major workers appearing once the colony reaches a larger size. ^[1]
