Pheidole havoana

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Madagascar, Anosy Region, Anosyenne Mountains at 1125m elevation in rainforest habitat. Nests found in rotten logs under stones and in root mats ^[1].
• Colony Type: Colony structure is unconfirmed for this specific species. Based on typical Pheidole patterns, they are likely monogyne (single queen), but this is not confirmed for P. havoana.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Pheidole genus to be around 4-6mm
  • Worker: Size data unavailable, inferred from Pheidole genus to be minute, with majors larger than minors
  • Colony: Unknown for this species
  • Growth: Moderate, inferred from genus patterns
  • Development: 6-10 weeks estimated based on typical Pheidole development at 24-28°C (Development time is estimated from related species, direct observations for P. havoana are not available)
• Antkeeping:
  • Temperature: Keep warm, roughly low-to-mid 20s°C, based on rainforest habitat ^[1].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, based on rainforest habitat ^[1].
  • Diapause: Based on tropical rainforest habitat, diapause is unlikely ^[1].
  • Nesting: Prefer humid nest environments. Y-tong or plaster nests work well. Naturalistic setups with moist soil and hiding structures mimic their natural rotten log habitat ^[1].
• Behavior: Based on typical Pheidole patterns, they are generalist foragers and not aggressive toward humans. Their tiny size makes them vulnerable to escape, so excellent barriers are needed.
• Common Issues: escape prevention is critical due to their minute size, they can squeeze through very small gaps, high humidity requirements can lead to mold issues if ventilation is poor, limited biological data means husbandry is largely based on genus inference, be prepared to experiment, wild-caught colonies may carry parasites or diseases from their native habitat, tropical warmth requirements may conflict with typical room temperature conditions in temperate homes

Housing and Nest Setup

For this tiny rainforest species, a Y-tong nest or plaster nest works well. The key requirement is maintaining high humidity while preventing flooding. Use a water reservoir connected to a cotton wick to provide moisture gradually. Nest chambers should be appropriately scaled for their minute size. A naturalistic setup with moist soil, pieces of rotting wood, and root material mimics their natural environment ^[1]. Ensure the outworld has tight-fitting barriers, these ants are tiny and excellent escape artists. Use fluon on container edges and fine mesh on ventilation holes.

Feeding and Diet

Based on typical Pheidole patterns, they are generalist foragers. In captivity, offer protein sources such as small insects and seeds, along with sugar sources like honey water. Feed protein 2-3 times per week and keep sugar water available constantly. Remove uneaten food promptly to prevent mold in the humid environment.

Temperature and Humidity

Maintain warm conditions, roughly low-to-mid 20s°C, based on their rainforest habitat ^[1]. Use a heating cable if room temperature is too low. Humidity should be kept high with consistently moist substrate, but avoid waterlogging. Provide a small dry area within the nest so workers can self-regulate.

Colony Development

Pheidole havoana is a recently described species, so specific development data is not available. Based on typical Pheidole genus patterns, expect 6-10 weeks from egg to first worker at optimal temperatures. The colony will grow gradually, with major workers appearing once the colony reaches several hundred workers. Pheidole colonies can live for several years with proper care.

Handling and Temperament

These ants are not aggressive and rarely bite. Their small size makes them difficult to handle directly. When observing or transferring colonies, use gentle techniques like blowing gently to encourage movement. Focus on excellent escape prevention rather than defensive behavior.
