Polyrhachis ceramensis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Moluccas Islands, Indonesia, tropical island environment ^[1].
• Colony Type: Based on Polyrhachis genus patterns, likely monogyne (single queen colonies), but unconfirmed for this species.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Polyrhachis genus patterns (~8-12 mm)
  • Worker: Size data unavailable, inferred from Polyrhachis genus patterns (~6-9 mm)
  • Colony: Up to several hundred workers, estimated based on genus patterns
  • Growth: Moderate, inferred from tropical species patterns
  • Development: Estimated 8-12 weeks at warm temperatures, but no specific data (Development is temperature-dependent, warmer conditions may speed growth)
• Antkeeping:
  • Temperature: Keep warm, roughly 26-28°C, based on tropical habitat inference
  • Humidity: Keep nest substrate consistently moist but not waterlogged, based on tropical habitat inference
  • Diapause: No, tropical species do not require diapause, inferred from habitat
  • Nesting: Prefers moist substrate and vertical space, based on genus patterns, use Y-tong, plaster, or soil nests with climbing structures
• Behavior: Generally peaceful and not aggressive toward keepers, based on genus patterns. Escape risk is moderate due to climbing ability, ensure enclosures are secure.
• Common Issues: high humidity is critical, too dry may cause colony stagnation or death, warm temperatures required, cool conditions may slow growth and brood development, colonies can be slow to establish, patience is needed during founding, escape prevention is important due to climbing ability, secure all gaps

Housing and Nest Setup

Use a naturalistic setup with moist substrate, such as Y-tong or plaster nests with a dirt chamber. Keep the nest substrate damp but not soggy, and include vertical elements for climbing. Since this species is from a humid tropical habitat, maintain consistent moisture. Provide a water reservoir or regular misting to help with humidity. The outworld should be escape-proof with barriers on edges.

Feeding and Diet

Polyrhachis ceramensis is omnivorous. Offer sugar sources like honey water or sugar water constantly. Provide protein such as small insects 2-3 times per week, and remove uneaten food after 24 hours to prevent mold. This is based on typical Polyrhachis genus feeding habits.

Temperature and Seasonal Care

Keep the colony warm, around 26-28°C, as inferred from its tropical habitat. Use a heating mat to create a gradient. No diapause is needed, but a slight temperature reduction in cooler months may be natural. Consistent warmth is key for colony health.

Colony Establishment and Growth

Founding behavior is unconfirmed, but based on genus patterns, queens may seal themselves in a chamber. The founding phase can take several weeks. Once workers emerge, offer small amounts of sugar and protein. Growth is moderate, colonies may take time to reach larger sizes. Patience is essential.
