Pheidole anosyenne

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to the Anosyenne Mountains, Toliara region, Madagascar. Found in rainforest at 1125 m elevation, nesting in a rotten log ^[1].
• Colony Type: Unconfirmed. Most Pheidole species are monogyne, but no data exist for P. anosyenne.
• Size & Growth:
  • Queen: Size data unavailable, the queen has not been described ^[1].
  • Worker: Size data unavailable, the original description gives only head measurements, not total body length ^[1].
  • Colony: Unknown, no colony size data exist ^[1].
  • Growth: Unknown, no documented growth rate for this species.
  • Development: Unknown, no documented development time for this species ^[1]. (Estimates from related Pheidole are speculative and not based on P. anosyenne data.)
• Antkeeping:
  • Temperature: Likely 20‑25 °C based on high‑elevation rainforest habitat. Provide a stable, warm environment, avoid extremes.
  • Humidity: Moderate to high. Keep the nest substrate consistently damp but not waterlogged, reflecting its rotten‑log microhabitat. A water tube helps.
  • Diapause: Unknown. Madagascar’s latitude suggests little seasonal cold, so true hibernation is unlikely, but no data exist. Monitor colony activity.
  • Nesting: Natural nest sites are rotten wood ^[1]. In captivity, offer Y‑tong or plaster nests with cork or wood fragments. Maintain humidity near the nesting area.
• Behavior: Behavior not documented in the original description ^[1]. Based on its rainforest habitat and typical Pheidole traits, it is probably not aggressive toward humans. Escape risk is moderate due to small size, use standard barriers (fluon/PTFE).
• Common Issues: limited data, this is a very newly described species with no captive care records, humidity must be carefully balanced, too dry kills the colony, too wet promotes mold, wild‑caught colonies may carry parasites or diseases with no known treatment, the queen is undescribed, making species verification difficult for purchased colonies

Housing and Nest Setup

Because the wild colony was found in a rotten log ^[1], an artificial nest that mimics that microhabitat is recommended. Start colonies in a standard test tube setup with a water reservoir. Once the colony outgrows the tube, move them to a Y‑tong or plaster nest that includes small pieces of cork or soft wood. Keep the nest area humid but not soaked. An outworld attached to the nest gives them room to forage without disturbing the queen.

Feeding and Diet

No dietary data exist for P. anosyenne. Based on the genus, they are likely omnivorous. Offer small protein sources (e.g., fruit flies, pinhead crickets) and a constant supply of sugar water or honey. Remove uneaten fresh food after 24 h to prevent mold. Because the species is undescribed in terms of feeding, start with small amounts and observe acceptance. ^[1]

Temperature and Humidity Management

The species was collected at 1125 m in a rainforest ^[1], so it likely prefers stable, moderately warm conditions. Aim for 20‑25 °C and avoid sudden drops. Humidity should be high, keep the nest substrate consistently moist (not waterlogged) and consider enclosing part of the nest to retain moisture. A water tube in the outworld provides drinking water.

Colony Growth and Development

No growth or development data are published for this species. The queen has not been described, and no founding observations exist ^[1]. Be prepared for an unknown timeline, patience is essential. If you obtain a wild‑caught queen, record your observations to help future keepers.

Handling and Observation

There are no records of aggression from this species. Given its small size and rainforest habits, it is probably non‑aggressive toward humans. Avoid disturbing the queen, especially during early colony stages. Once established, you can watch the majors and minors work, but no specific behavior has been documented. Use a red filter or low light to minimize stress. ^[1]
