Pheidole braueri

Quick Summary

• Difficulty: Unknown
• Origin & Habitat: Silhouette Island, Seychelles, collected from forest habitats ^[1][2]
• Colony Type: Unconfirmed, likely monogyne based on typical Pheidole patterns ^[3]
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements in literature. Inferred from Pheidole genus: ~5-8 mm
  • Worker: Size data unavailable, no total length measurements. Inferred from Pheidole genus: major workers up to ~3 mm, minor workers up to ~2 mm
  • Colony: Unknown
  • Growth: Moderate (inferred from genus patterns)
  • Development: Estimated 6-8 weeks at 25-28°C (inferred from Pheidole genus) ^[3] (Development timeline is inferred from genus-level data since no species-specific studies exist)
• Antkeeping:
  • Temperature: Keep at 24-28°C, inferred from tropical island habitat ^[1][2]
  • Humidity: Maintain moderate humidity, inferred from forest habitat ^[1][2]
  • Diapause: No, as species is from tropical island near equator ^[1][2]
  • Nesting: Inferred from genus: likely nest in soil or wood, in captivity, test tube setup for founding, Y-tong or plaster nest for growth ^[3]
• Behavior: Pheidole ants are generally non-aggressive but will defend their nest. Major workers have enlarged heads for seed crushing. They have a functional sting as typical for Myrmicinae, but it is less medically significant to humans. Escape risk is high due to tiny minor workers, use fine mesh barriers.
• Common Issues: minor workers can escape through standard test tube cotton or gaps, use fine mesh and check connections regularly, lack of species-specific care information means keepers must rely on genus-level guidance, overfeeding can lead to mold in small nest setups, remove uneaten prey promptly, slow colony growth may require patience and careful monitoring

Appearance and Identification

Pheidole braueri has two worker castes. Major workers have a rectangular head longer than wide, with strongly divergent frontal carinae ^[1]. Minor workers have a subrectangular head with smooth to weakly punctate face ^[1]. Both castes have short scapes and legs, and the color is reddish brown with lighter legs and darker gaster ^[1]. This species is only known from Silhouette Island, making it a potential endemic ^[1][2].

Natural History and Distribution

This species is restricted to Silhouette Island in the Seychelles, where it has been collected in forest habitats ^[1][2]. No published biological studies exist beyond specimen measurements and distribution ^[1][2]. This makes it both interesting as a rare endemic and challenging due to lack of care literature.

Housing and Nest Setup

For founding, use a test tube setup with water and cotton ^[3]. Once workers emerge, transition to a Y-tong or plaster nest scaled to their tiny size ^[3]. Keep nest chambers appropriate for minor workers, and ensure fine mesh barriers to prevent escape ^[3].

Feeding and Diet

Like most Pheidole, they are omnivorous. Offer small protein sources like fruit flies and sugar water ^[3]. Prey should be appropriately small for their size, and uneaten food removed promptly to prevent mold ^[3].

Temperature and Humidity

Keep at 24-28°C, inferred from tropical habitat ^[1][2]. Maintain moderate humidity with moist but not waterlogged substrate, inferred from forest environment ^[1][2].

Colony Development and Growth

Founding queens likely seal themselves in, but founding type is unconfirmed. Development from egg to worker is estimated 6-8 weeks at 25-28°C, inferred from genus patterns ^[3]. Colony growth is slow initially, but no specific size data exists.
