Polyrhachis imitator

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Sulawesi, Indonesia, found in cacao plantations at elevations around 815 m ^[1].
• Colony Type: Colony structure is unconfirmed. Based on Polyrhachis patterns, likely monogyne (single queen) colonies.
• Size & Growth:
  • Queen: ~9.8 mm ^[1]
  • Worker: ~6.5-7.2 mm ^[1]
  • Colony: Unknown, no colony size data available.
  • Growth: Moderate
  • Development: Estimated 6-10 weeks at optimal temperatures, based on related Polyrhachis species ^[2]. (Development time may vary with temperature.)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, as inferred from their tropical habitat.
  • Humidity: Keep nest substrate consistently moist but not waterlogged. As arboreal ants, they prefer high humidity ^[2].
  • Diapause: No, as a tropical species, they do not require diapause.
  • Nesting: Provide arboreal-style nests with vertical orientation, such as Y-tong or cork bark setups ^[2].
• Behavior: Workers are relatively calm and non-aggressive. They are skilled climbers due to their arboreal nature ^[2]. Escape prevention should be moderate due to their medium size and climbing ability.
• Common Issues: tropical species may struggle in cool or dry environments, maintain warmth and humidity., arboreal nature requires vertical space and climbing structures., limited availability in the antkeeping hobby, may be difficult to acquire., escape prevention needed due to climbing ability., humidity control is critical, too dry causes dehydration, too wet causes mold.

Housing and Nest Setup

Provide an arboreal-style setup that mimics their natural canopy-dwelling habitat. Use a Y-tong nest with multiple chambers or a naturalistic setup with cork bark and branches ^[2]. Include climbing structures and ensure tight-fitting lids to prevent escapes.

Feeding and Diet

Polyrhachis imitator is omnivorous. Offer sugar water, honey, or diluted maple syrup as a constant carbohydrate source. Provide protein such as small insects 2-3 times per week ^[2].

Temperature and Humidity

Maintain temperatures between 24-28°C with a slight gradient. Humidity should be kept high, use a moisture reservoir and mist occasionally to maintain substrate moisture ^[2].

Behavior and Temperament

Workers are calm and non-aggressive. They have a distinctive three-spined petiole, which may serve as a defensive adaptation ^[1]. Provide enrichment with climbing structures.

Colony Development

The queen measures about 9.8 mm and workers 6.5-7.2 mm ^[1]. Development time is unconfirmed, but estimated 6-10 weeks for first workers based on related species ^[2].
