Pheidole penetralis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Mysol island in the Moluccas, Indonesia, a tropical archipelago environment ^[1].
• Colony Type: Based on Pheidole genus patterns, likely monogyne (single queen) colonies.
• Size & Growth:
  • Queen: size unknown, inferred from Pheidole genus patterns to be typically small, around 6-8 mm
  • Worker: minor workers around 2-3 mm, major workers around 3-5 mm with enlarged heads, inferred from Pheidole genus patterns
  • Colony: Up to several hundred workers
  • Growth: Moderate
  • Development: Estimated 6-8 weeks at tropical temperatures, inferred from typical Pheidole development (Development time varies with temperature, warmer conditions accelerate development)
• Antkeeping:
  • Temperature: Keep at 24-28°C, based on tropical habitat inference. Provide a slight gradient for self-regulation.
  • Humidity: Maintain moderate to high humidity, keep nest substrate slightly moist but not waterlogged, based on tropical forest inference.
  • Diapause: No, as a tropical species, they do not require hibernation, based on geographic range inference.
  • Nesting: Use test tube setup for founding, transition to Y-tong or plaster nests with damp soil once established, based on genus preferences inference.
• Behavior: Pheidole penetralis is generally peaceful toward keepers. Major workers defend the colony using their enlarged heads and can sting, but the sting is less medically significant to humans. Minor workers are small and pose escape risk, so ensure all connections are sealed. They are not aggressive but may bite if handled roughly.
• Common Issues: colonies may fail if humidity drops too low, keep substrate consistently moist., major workers can get stuck in narrow tubing if connections are too tight., wild-caught colonies may contain parasites that cause colony collapse., overfeeding can lead to mold problems in the nest., slow initial growth during founding phase may cause keepers to abandon colonies prematurely.

Housing and Nest Setup

For founding colonies, use a test tube setup with water and cotton for humidity. Cover the tube to simulate darkness. Once the colony has 30-50 workers, transition to a Y-tong or plaster nest with small chambers. Connect to an outworld with tubing, and ensure all connections are tight to prevent escape by minor workers.

Feeding and Diet

Offer a varied diet: protein sources like small insects 2-3 times per week, seeds, and constant sugar water. Remove uneaten food after 24-48 hours to prevent mold. Fresh water should always be available.

Temperature and Seasonal Care

Maintain temperatures between 24-28°C. Use heating cables if needed, placed on top of the nest. They do not require hibernation but may reduce activity in cooler temperatures.

Colony Development and Growth

A queen will seal herself in during founding and lay eggs. First workers emerge in 6-8 weeks at tropical temperatures. Once workers are active, offer food in the outworld. Colony growth is moderate, reaching up to several hundred workers over time.

Behavior and Handling

This species is peaceful but major workers can sting, though the sting is not harmful to humans. Minor workers are small and require tight seals to prevent escape. The colony establishes foraging patterns and recruits efficiently via chemical trails.
