Polyrhachis boltoni

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Lowland dipterocarp rainforests of Borneo, Brunei, Malaysia, and Indonesia. Nests are built arboreally in trees, often in canopy areas ^[4][1].
• Colony Type: Polydomous, colonies likely occupy multiple connected arboreal nests. No queen was found in studied nests, suggesting the colony spreads across locations, but queen number is unconfirmed ^[1].
• Size & Growth:
  • Queen: ~8 mm ^[1]
  • Worker: ~7 mm ^[1]
  • Colony: Up to 85 workers per nest ^[1]
  • Growth: Moderate, estimated based on tropical arboreal ant patterns
  • Development: Unknown, no specific data for this species (Development time is unclear, tropical species may develop faster than temperate ones.)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical rainforest patterns
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as they are from humid rainforests
  • Diapause: No, tropical species do not require hibernation
  • Nesting: Arboreal setup with vertical space and materials for silk weaving, such as leaves and detritus ^[2][3][1]
• Behavior: Diurnal and peaceful, with low aggression but escape risk due to small size, workers flee when disturbed ^[1].
• Common Issues: arboreal nesting requirements make setup challenging, they need vertical space and weaving materials, high humidity needs can lead to mold if ventilation is poor, escape prevention is important due to small size and arboreal nature, polydomous colonies may be stressed in single-nest setups, consider multiple connected areas, tropical warmth requirements year-round mean consistent heating is essential

Housing and Nest Setup

P. boltoni requires an arboreal setup that mimics their natural rainforest canopy habitat. Create a naturalistic enclosure with vertical space, branches, or leaves where they can build silk-woven nests. Provide materials like small leaf fragments or wood pieces for weaving. Position the nest at least 30cm above the floor, with high humidity and adequate ventilation to prevent mold ^[2][3][1].

Feeding and Diet

In the wild, workers forage on detritus from leaves and rotting wood. In captivity, offer sugar sources like honey water and protein such as fruit flies or mealworms. Feed small amounts 2-3 times per week, removing uneaten food to prevent mold ^[1].

Temperature and Humidity

As a tropical species, keep temperatures warm, roughly 24-28°C, with a gradient using a heating cable. Humidity should be maintained by keeping the nest substrate moist but not waterlogged, with occasional misting.

Colony Structure and Polydomy

P. boltoni appears polydomous, with colonies spread across multiple nests in the canopy. Studied nests contained up to 85 workers, but no queen was found, suggesting satellite nests. In captivity, provide connected nesting areas to reduce stress ^[1].

Behavior and Activity

Workers are diurnal, active during daylight, and peaceful, fleeing when disturbed. Their small size and arboreal nature mean escape prevention is crucial ^[1].
