Pheidole laevinota

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Subtropical evergreen forests of Argentina and Brazil at 750-900m elevation ^[1]
• Colony Type: Likely monogyne (single queen) based on typical Pheidole patterns, but unconfirmed for this species
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements found in research
  • Worker: Size data unavailable, body length not specified, but majors and minors exist
  • Colony: Up to 148 workers observed in studies ^[2]
  • Growth: Moderate, estimated based on genus patterns
  • Development: Estimated 6-8 weeks based on typical Pheidole development (Development may vary with temperature)
• Antkeeping:
  • Temperature: Keep at room temperature (20-25°C) with a gentle gradient, based on subtropical habitat ^[1]
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as they inhabit subtropical forests ^[1]
  • Diapause: Likely requires a mild winter rest period of 2-3 months at cooler temperatures, based on temperate/subtropical patterns
  • Nesting: In nature, they nest in soil or under stones. In captivity, use test tube setups for founding, then transition to Y-tong or plaster nests
• Behavior: Pheidole are generally non-aggressive and shy. Majors have enlarged heads for seed crushing but are not highly defensive. Escape risk is moderate due to small size of minors
• Common Issues: small minors can escape through gaps larger than 0.5mm, ensure proper sealing., mold can develop if food is not removed promptly., test tube setups can flood if water reservoirs are overfilled., winter dormancy requirements are unconfirmed, observe colony behavior., colony growth may be slow, leading to overfeeding and mold.

Housing and Nest Setup

For founding colonies, use a standard test tube setup. Fill the tube with water and plug the wet end with cotton to maintain humidity. Cover the tube with a dark cloth to simulate natural conditions. Once the colony reaches 20-30 workers, transition to a small formicarium. Use Y-tong or plaster nests for established colonies. Ensure escape prevention by using fluon barriers on rim edges, as minor workers are small.

Feeding and Diet

Pheidole species are typically omnivorous with a preference for seeds and protein. In captivity, offer a varied diet including small seeds like millet or sesame, protein sources like fruit flies or mealworms, and sugar water or honey. Major workers have enlarged mandibles for seed crushing. Feed protein 2-3 times per week and keep sugar sources available. Remove uneaten food after 24-48 hours to prevent mold.

Temperature and Seasonal Care

Pheidole laevinota comes from subtropical forests, so keep temperatures around 20-25°C with a gentle gradient. During winter months, expect reduced activity and consider a cool period around 10-15°C for 2-3 months to simulate natural cycles, though this is unconfirmed for this species.

Colony Development and Growth

Pheidole colonies grow through stages: queen lays eggs, which hatch into larvae, then pupate before emerging as workers. First workers are smaller and help with colony maintenance. As the colony grows, major workers develop with enlarged heads. A mature colony may reach up to 148 workers based on studies ^[2]. Growth is moderate, taking 6-12 months to reach 50 workers under good conditions.
