Polyrhachis aporema

Quick Summary

• Difficulty: Medium
• Origin & Habitat: New Britain Island, East New Britain Province, Papua New Guinea, in rainforest habitats at approximately 600 m elevation ^[1].
• Colony Type: Likely monogyne (single-queen colonies) based on subgenus patterns, but unconfirmed for this species.
• Size & Growth:
  • Queen: ~7.41 mm ^[1]
  • Worker: 6.35-7.15 mm ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Unknown, no specific data
  • Development: Unknown, no direct data. Based on Polyrhachis patterns, estimate 6-10 weeks at optimal temperature. (Development is unconfirmed, tropical temperatures may affect timing.)
• Antkeeping:
  • Temperature: Keep warm around 24-28°C, based on tropical rainforest habitat. Temperature needs are unconfirmed, start here and observe.
  • Humidity: Keep nest substrate consistently moist but not waterlogged, based on rainforest origin.
  • Diapause: No diapause required, as tropical species do not experience cold winters.
  • Nesting: Arboreal nests with silk, confirmed from research ^[2]. Provide vertical setups with materials for silk attachment.
• Behavior: Generally calm and non-aggressive. Arboreal foragers likely searching for nectar and small prey. Escape risk is moderate due to climbing ability, ensure tight-fitting lids. Defense mechanism: lacks a functional sting but can bite and spray formic acid, typical of Formicinae.
• Common Issues: humidity management is critical, too wet causes fungal growth, too dry stresses the colony., arboreal nesting requires vertical space and silk-friendly materials., limited species-specific information means care may require adaptation., tropical temperature needs year-round may increase heating costs., escape prevention is important due to climbing agility.

Nest Preferences and Housing

Polyrhachis aporema builds silk nests between leaves in arboreal locations ^[2]. In captivity, provide vertical setups with materials like cork, artificial nests, or live plants for silk attachment. Avoid horizontal orientations, mimic tree-dwelling lifestyle with adequate ventilation to prevent mold in humid conditions ^[2][1].

Feeding and Diet

This species is omnivorous, foraging for nectar, honeydew, and small invertebrates. In captivity, offer sugar water or honey constantly, and protein like small crickets or mealworms 2-3 times per week. Remove uneaten food after 24 hours to prevent mold. Fresh water should always be available.

Temperature and Seasonal Care

As a tropical species, keep temperatures around 24-28°C year-round with no diapause. Use a heating cable on one side of the nest to create a gradient for self-regulation. Monitor with a thermometer, avoid temperatures below 22°C to prevent stress.

Behavior and Colony Dynamics

Workers are moderately sized and relatively calm, foraging in arboreal habitats. Colonies are likely monogyne, starting with a single queen. The queen is larger than workers, with typical sexual morphology ^[1]. Growth rate is unconfirmed but likely moderate based on related species ^[2].
