Polyrhachis clio

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Torresian region (northern Australia, New Guinea and surrounding islands). Found in humid tropical forests and woodland areas. Nests in rotting wood ^[1][2].
• Colony Type: Unconfirmed, no species-specific data on queen number.
• Size & Growth:
  • Queen: Size data unavailable for P. clio, but inferred from Polyrhachis genus as moderate-sized.
  • Worker: Size data unavailable for P. clio, but inferred from Polyrhachis genus as moderate-sized.
  • Colony: Unknown
  • Growth: Moderate (inferred from genus patterns)
  • Development: Unknown, no species-specific data (Development time is unconfirmed for P. clio.)
• Antkeeping:
  • Temperature: Based on tropical habitat, keep warm, roughly 24-28°C (inferred).
  • Humidity: Keep nest substrate slightly moist, based on lignicolous nesting habits ^[2][3].
  • Diapause: No, tropical species do not require hibernation (inferred).
  • Nesting: Lignicolous nesting preferences, use wood-based nests such as Y-tong or wooden formicaria ^[2][3].
• Behavior: Generally calm temperament based on Subordinate Camponotini functional group ^[1]. Moderate escape risk, use standard barrier methods.
• Common Issues: wood nesting requirements mean standard test tubes may not be ideal, provide appropriate nesting material, tropical warmth needs year-round heating to prevent colony decline, limited species-specific care information means some adaptation may be needed, wild-caught colonies may harbor parasites that affect captive survival

Nest Preferences and Housing

Polyrhachis clio is a lignicolous species, meaning it naturally nests in rotting wood ^[2][3]. In captivity, this translates to preferring wood-based or cavity nests rather than soil-filled setups. Y-tong (AAC) nests work well because they provide dark, enclosed chambers that mimic natural wood cavities. You can also use wooden formicaria or create naturalistic setups with pieces of rotting wood. Ensure the nest material stays slightly moist but never waterlogged ^[2][3].

Feeding and Diet

Polyrhachis ants are omnivorous like most Formicinae. They accept both sugar sources and protein. Offer sugar water, honey, or diluted syrup as a constant carbohydrate source. For protein, provide small insects like fruit flies, mealworms, or other appropriately sized prey. Feed protein 2-3 times per week, and keep sugar water available at all times. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Heating

Based on tropical habitat, keep temperatures warm, roughly 24-28°C. Use a heating cable or heat mat to maintain this range, creating a gradient for the colony to self-regulate. Avoid temperatures below 20°C for extended periods, as this species is not cold-tolerant.

Humidity and Water

Keep the nest substrate slightly moist, based on lignicolous nesting habits ^[2][3]. Avoid waterlogged conditions, which can lead to mold. In naturalistic setups, a small water dish in the outworld provides drinking water.

Behavior and Colony Dynamics

Polyrhachis clio workers are moderately active and forage individually. They belong to the Subordinate Camponotini functional group, which generally means they are less aggressive than many ant species ^[1]. Workers can defend themselves if threatened, but they typically avoid conflict. The presence of pupal cocoons means you'll see more developed brood than with naked pupae species.
