Pheidole nitidobruna

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Northern Madagascar (Antsiranana region), Makirovana forest at 550m elevation in rainforest habitat, nesting in rotten logs ^[1].
• Colony Type: Based on Pheidole genus patterns, likely monogyne (single queen) colonies.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Pheidole genus patterns as ~6-8mm ^[2]
  • Worker: Size data unavailable, inferred from Pheidole genus patterns as ~1-2mm ^[2]
  • Colony: Up to several thousand workers inferred from genus patterns ^[2]
  • Growth: Moderate
  • Development: Estimated 5-8 weeks at optimal temperatures, inferred from related species ^[2] (Development is temperature-dependent, warmer conditions accelerate growth)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical rainforest habitat ^[1].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, based on rainforest habitat ^[1].
  • Diapause: No, this tropical species does not require hibernation.
  • Nesting: Prefer damp, decaying wood habitats, use Y-tong, plaster, or soil nests with a moisture gradient to simulate rotten log conditions.
• Behavior: Pheidole nitidobruna is generally calm but possesses a sting, though it is less medically significant to humans. Major workers defend the colony, while minors handle foraging and brood care. Their very small size requires excellent escape prevention.
• Common Issues: escape prevention is critical due to very small size, even minor gaps allow escape., high humidity requirements can lead to mold if ventilation is poor., tropical species will decline if temperatures drop below 20°C., colonies may be slow to establish initially, patience is needed during founding., wild-caught colonies may carry parasites that can affect captive health.

Housing and Nest Setup

For founding colonies, use a test tube setup with water and cotton, placed in a dark area. The queen will seal herself in and raise the first brood. Once workers emerge, transition to a small formicarium. For established colonies, use Y-tong, plaster, or soil nests with a water reservoir to maintain moisture. Include damp substrate or rotting wood to simulate their natural habitat. An outworld allows foraging observation ^[1].

Feeding and Diet

This species is omnivorous. Offer protein sources like fruit flies or pinhead crickets, and carbohydrates like sugar water or honey. Feed protein 2-3 times per week and keep sugar available. Remove uneaten prey after 24-48 hours to prevent mold ^[2].

Temperature and Seasonal Care

Maintain warm conditions around 24-28°C year-round, as this is a tropical species. Use a heating cable for a gentle gradient. Do not expose to temperatures below 20°C for extended periods. No diapause is needed ^[1].

Colony Development and Growth

Colonies start with claustral founding, though this is unconfirmed for this species. First workers emerge in 5-8 weeks at optimal temperatures. Growth is moderate, with majors appearing as the colony matures. A mature colony can have thousands of workers ^[2].

Behavior and Temperament

Pheidole nitidobruna is peaceful but has a sting for defense. Major workers protect the colony, while minors forage. They use chemical trails and are active foragers. Escape prevention is crucial due to their tiny size ^[1].
