Polyrhachis monteithi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: North Queensland, Australia, from Cooktown to Mackay. Nests in silk and vegetation between leaves in rainforests and gallery forests ^[1][2][3].
• Colony Type: Unconfirmed, colony structure not specifically documented for this species.
• Size & Growth:
  • Queen: ~7.11-7.76 mm total length ^[1]
  • Worker: ~5.54-6.75 mm total length ^[1]
  • Colony: Unknown, no specific data available
  • Growth: Moderate, inferred from typical Polyrhachis patterns
  • Development: Estimated 6-10 weeks at optimal temperatures (Development time is estimated based on related species, pupae develop naked without cocoons ^[2][3].)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, as a tropical species.
  • Humidity: Keep nest substrate consistently moist but not waterlogged, typical for rainforest species.
  • Diapause: No, tropical species do not require hibernation.
  • Nesting: Arboreal nests using silk to bind leaves. Provide materials like cotton or leaves for weaving in captivity ^[2][3].
• Behavior: Weaver ant behavior, workers use silk to construct nests. Moderately active, forage for honeydew and small prey. Escape risk is moderate due to size.
• Common Issues: high humidity maintenance can be challenging, poor humidity leads to desiccation and colony decline., arboreal nature requires vertical space and weaving materials, flat nests may not be accepted., lack of cocoons means pupae are vulnerable to disturbance, avoid moving nests unnecessarily., tropical species cannot tolerate cool temperatures, cold exposure kills colonies., new colonies have slow initial growth, keepers may overfeed or disturb them prematurely.

Nest Preferences and Housing

Polyrhachis monteithi is an arboreal species that builds nests between leaves using silk. In captivity, provide materials like cotton fibers, small leaves, or fabric strips that workers can manipulate with silk ^[2][3]. Use a vertical setup with branches or plants in the outworld to mimic natural conditions. Y-tong nests with multiple chambers can work, but add weaving materials for nest construction.

Feeding and Diet

This species is omnivorous, likely feeding on honeydew, nectar, and small insects. In captivity, offer sugar water or honey regularly and provide protein sources like fruit flies or mealworms. Feed small amounts 2-3 times per week, removing uneaten food after 24 hours.

Temperature and Seasonal Care

As a tropical species from north Queensland, keep temperatures warm year-round, roughly 24-28°C ^[1]. Use a heating cable on one side of the nest to create a gradient. Avoid temperatures below 20°C for extended periods. No hibernation is needed.

Weaver Ant Behavior and Colony Setup

Polyrhachis monteithi uses silk produced by larvae to bind leaves together for nest construction, and pupae develop naked without cocoons ^[2][3]. When setting up your colony, provide materials for weaving and ensure vertical space for arboreal nesting.

Growth and Development

Development from egg to worker is estimated at 6-10 weeks at optimal temperatures. New colonies grow slowly, with first workers being smaller than normal. Colonies may reach several hundred workers over time, but specific data is unavailable.
