Polyrhachis phalerata

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Tropical Southeast Asia, found in the Philippines, Thailand, Laos, Malaysia, Borneo, Cambodia, and Indonesia. Inhabits tropical forest environments where it builds carton nests attached to vegetation ^[2][5].
• Colony Type: Unconfirmed, no specific data on queen number or social structure.
• Size & Growth:
  • Queen: Size data unavailable
  • Worker: Size data unavailable
  • Colony: Estimated up to several hundred workers, inferred from Polyrhachis genus patterns
  • Growth: Moderate, inferred from tropical species patterns
  • Development: Unknown, no data available (Development time likely varies with temperature)
• Antkeeping:
  • Temperature: Keep warm, around 24-28°C, inferred from tropical species needs
  • Humidity: Keep substrate consistently moist but not waterlogged, inferred from forest-dwelling habits
  • Diapause: No, tropical species do not require hibernation
  • Nesting: Prefer carton nests, use Y-tong or naturalistic setup with moist substrate ^[5]
• Behavior: Polyrhachis phalerata is calm and not aggressive toward keepers. Workers forage for honeydew, nectar, and small insects. As Formicinae ants, they defend by spraying formic acid, this can irritate skin and eyes but is not dangerous. They are moderate escape artists, ensure tight-fitting lids and use barriers. They are semi-arboreal, so appreciate vertical space in their outworld.
• Common Issues: tropical species may struggle if temperatures drop below 20°C, use a heating setup in cooler climates, carton-nesting behavior means they prefer humid conditions, dry nests can cause colony decline, escape prevention is important as workers can squeeze through small gaps, use fluon on container edges, wild-caught colonies may carry parasites, quarantine and monitor new colonies carefully, slow colony growth can frustrate beginners, be patient and avoid disturbing the nest too often

Housing and Nest Setup

Polyrhachis phalerata naturally builds carton nests from plant fibers, wax, and resin ^[5]. In captivity, replicate this with a naturalistic setup using materials like cork or dried plant matter. A Y-tong formicarium with moist substrate also works well. These ants are semi-arboreal, so provide an outworld with climbing opportunities like twigs or mesh. Use a test tube setup for founding colonies, then move to a formicarium once the colony has workers. Ensure excellent escape prevention, these ants can squeeze through small gaps.

Temperature and Heating

As a tropical species, P. phalerata needs warm conditions. Keep the nest area at 24-28°C for optimal brood development. Room temperature may suffice in warm climates, but in temperate regions, use a heating cable on one side of the nest to create a gradient. Avoid temperatures below 20°C for extended periods, as this can weaken the colony.

Feeding and Diet

Polyrhachis ants are omnivorous, feeding on honeydew, nectar, and small insects. In captivity, offer sugar water or diluted honey as a constant carbohydrate source. Provide protein like fruit flies or small crickets 2-3 times per week. Remove uneaten prey after 24 hours to prevent mold.

Humidity and Water

Tropical forest ants need moderate to high humidity. Keep the nest substrate consistently moist but not waterlogged. Provide a water tube for drinking water. Mist the outworld occasionally in dry climates, but avoid excessive moisture that leads to mold.

Colony Founding and Growth

A newly mated queen may seal herself in a chamber to raise the first brood. This founding phase can take several weeks before workers emerge. Colony growth is slow initially but accelerates once established. Be patient during founding, disturbing the queen often leads to failure.

Behavior and Temperament

Polyrhachis phalerata is relatively calm and not aggressive. Workers are active foragers that explore systematically. As Formicinae ants, they spray formic acid as defense, this can cause mild irritation but is not dangerous. Workers live for several months, while queens can live for years in well-established colonies.
