Polyrhachis tubifera

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Eastern Australia, from Cape York Peninsula to Brisbane, in open eucalypt forests and woodlands ^[1][2].
• Colony Type: Colony structure is unconfirmed, as no specific data is available ^[1].
• Size & Growth:
  • Queen: 7.31-7.36 mm ^[1]
  • Worker: 5.49-7.25 mm ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown, no specific data on growth rate
  • Development: Estimated 8-12 weeks based on related Polyrhachis species (Development time is not documented for P. tubifera.)
• Antkeeping:
  • Temperature: Keep warm, roughly 22-26°C, based on typical conditions for subtropical ants.
  • Humidity: Keep substrate consistently moist but not waterlogged.
  • Diapause: No diapause required, as the species is from subtropical Australia.
  • Nesting: Subterranean nests with leaf litter cover are preferred ^[1][2].
• Behavior: Workers are moderately active and forage on the ground. They are not highly aggressive but will defend the nest if threatened.
• Common Issues: colonies may be slow to establish, patience is needed during founding., overheating can be fatal, avoid temperatures above 30°C., dry substrate can lead to colony mortality.

Housing and Nest Setup

Polyrhachis tubifera is a ground-nesting species that prefers subterranean nests covered with leaf litter ^[1][2]. In captivity, use Y-tong (AAC) nests, plaster nests, or naturalistic setups with soil substrate. Provide a nest chamber at least 10-15 mm deep to allow burrowing. The outworld should include leaf litter or debris to mimic their natural habitat ^[1].

Feeding and Diet

These ants are omnivorous, accepting sugar sources like honey water and protein foods such as small insects. Offer sugar water constantly and protein 2-3 times per week, removing uneaten prey after 24 hours to prevent mold.

Temperature and Seasonal Care

Keep temperatures around 22-26°C, with a gentle gradient using a heating cable if needed. Avoid temperatures above 30°C. No diapause is required, but a slight cooling period in winter may benefit the colony.

Behavior and Colony Dynamics

Workers are moderately active foragers on the ground. They defend the nest when disturbed but are not overly aggressive. Queens are capable of founding colonies, but the exact method is unconfirmed ^[1].

Handling and Escape Prevention

At 5.5-7.25 mm, workers are large enough to handle easily. Use standard barriers like fluon to prevent escapes, as they can squeeze through small gaps. Handle gently to avoid stressing the colony.
