Pheidole itremo

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Central Madagascar highlands (Fianarantsoa and Antananarivo provinces), montane forest and montane rainforest at 1410-1620m elevation ^[1][2]
• Colony Type: Based on Pheidole genus patterns, likely single-queen colonies (monogyne) ^[2]
• Size & Growth:
  • Queen: Size data unavailable, inferred from Pheidole genus patterns to be around 5-7mm ^[2]
  • Worker: Size data unavailable, inferred from Pheidole genus patterns to be small-bodied ^[2]
  • Colony: Up to several hundred workers, estimated from related species ^[2]
  • Growth: Moderate, typical for Pheidole genus ^[2]
  • Development: 6-10 weeks estimated based on genus patterns ^[2] (Development time inferred from typical Pheidole development at room temperature)
• Antkeeping:
  • Temperature: Based on high-elevation habitat, keep at cooler temperatures around 20-24°C ^[1]
  • Humidity: Keep nest substrate consistently moist, as they nest in rotten logs in montane rainforest ^[1]
  • Diapause: Based on highland Madagascar origin, they may require cooler seasonal temperatures, but specific diapause requirements are unknown ^[1]
  • Nesting: In captivity, they do well in Y-tong (AAC) nests, plaster nests, or naturalistic setups with rotting wood pieces. They naturally nest in rotten logs and root mats, so include wood fragments or cork in the nest ^[1][2]
• Behavior: Typical Pheidole behavior, majors have enlarged heads for seed-processing and colony defense. Workers are active foragers, and colonies will defend vigorously. Minor workers are small and can escape through small gaps, use fine mesh barriers. They are not aggressive toward humans and rarely sting ^[2]
• Common Issues: escape prevention is critical due to tiny minor workers, use fine mesh and tight-fitting lids., high humidity needs can lead to mold if ventilation is poor., colonies may be slow to establish initially, patience is needed during founding., wild-caught colonies may carry parasites that can decimate the colony.

Housing and Nest Setup

You can use Y-tong (AAC) nests, plaster nests, or naturalistic soil setups with rotting wood pieces to simulate their natural habitat ^[1][2]. Always provide an outworld connected to the nest. For founding queens, use a test tube setup with a water reservoir cotton ball for humidity. Once the colony reaches 20-30 workers, move them to a larger setup if needed.

Feeding and Diet

Offer a varied diet including protein sources like small insects (fruit flies, mealworms) and carbohydrates like sugar water or honey ^[2]. Feed protein 2-3 times per week and keep a constant sugar source available. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Humidity

Keep temperatures around 20-24°C based on their high-elevation origin ^[1]. For humidity, maintain a moist nest substrate without waterlogging, as they nest in rotten logs in montane rainforest ^[1]. Use a water reservoir or mist the nest when dry.

Colony Development

Queens may lay eggs after sealing themselves in, but founding behavior is unconfirmed. First workers emerge in 6-10 weeks at room temperature ^[2]. Growth is moderate, with colonies reaching up to several hundred workers over time ^[2]. Major workers become more common as the colony matures.

Behavior and Observation

Minor workers handle foraging and brood care, while majors defend the colony and process seeds ^[2]. Foraging is highest during evening hours. This species is not aggressive toward keepers and rarely stings ^[2].
