Pheidole cuprina

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the Neotropical region, specifically Peru and French Guiana. Found in terra firme tropical rainforest at low elevations around 200m, nesting in rotting wood and leaf litter ^[1][2].
• Colony Type: Monogyne, single queen colonies, based on AntWiki observations of the type colony ^[1].
• Size & Growth:
  • Queen: Size data unavailable, but inferred from Pheidole genus patterns to be approximately 6-7mm total length ^[1].
  • Worker: Size data unavailable, but inferred from Pheidole genus patterns: majors around 5-6mm, minors around 2-3mm total length ^[1].
  • Colony: Up to several hundred workers in mature colonies ^[1].
  • Growth: Moderate
  • Development: 6-10 weeks estimated at optimal temperature ^[1]. (Development is faster in warm, humid conditions typical of their natural habitat.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. These tropical ants require warm, stable temperatures. A heating cable on one side of the nest creates a gradient for self-regulation ^[1].
  • Humidity: Keep the nest substrate consistently moist but not waterlogged, as they inhabit humid rainforest ^[1].
  • Diapause: No, as a tropical species, they do not require hibernation. Keep temperatures stable year-round ^[1].
  • Nesting: Use Y-tong (AAC) or plaster nests that retain moisture. Provide chambers scaled to their size. Test tube setups work for founding colonies but may need transfer as the colony grows ^[1].
• Behavior: Pheidole cuprina is non-aggressive toward keepers. Majors defend the colony if threatened, using their stinger, but it is mild. Workers forage individually for seeds and small prey. Escape prevention is important due to their small size, use standard barriers ^[1].
• Common Issues: temperatures below 22°C can slow activity and weaken the colony, dry conditions cause brood death and colony decline, small colony size means slow growth, requiring patience, wild-caught colonies may carry parasites, rotting wood nesting preference requires humid, organic-rich substrate

Housing and Nest Setup

Use Y-tong (AAC) or plaster nests with moisture reservoirs for Pheidole cuprina. These hold humidity well and provide a dark, humid environment. For founding colonies, a test tube setup can work, but monitor humidity closely. An outworld allows foraging, and apply fluon to barriers to prevent escapes ^[1].

Feeding and Diet

Offer a varied diet: seeds like millet for majors to crack, protein sources like fruit flies, and sugar water. Feed protein 2-3 times per week and keep sugar water available. Remove uneaten food to prevent mold ^[1].

Temperature and Humidity

Keep nest temperature at 24-28°C using a heating cable for a gradient. Humidity should be maintained with moist substrate, avoiding waterlogging. Dry conditions can kill brood ^[1].

Colony Development

Colonies grow moderately. A claustral queen raises first workers in 6-10 weeks at optimal temperature. Initial workers are few, then foraging begins. Growth to 100 workers may take 6-12 months with good care ^[1].

Behavior and Observation

Minor workers handle foraging and brood care, while majors crack seeds and defend. When disturbed, majors may display with open mandibles but rarely bite aggressively. This division of labor makes observation rewarding ^[1].
