Polyrhachis cybele

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Southeast Asia, Borneo, Sumatra, Java, Sulawesi, and Philippines. Inhabits tropical forest environments ^[1][2].
• Colony Type: Colony structure is unconfirmed, no specific literature on queen number or social structure for this species.
• Size & Growth:
  • Queen: 8.26 mm ^[1][2]
  • Worker: 5.95-7.96 mm ^[1][2]
  • Colony: Unknown, no data on maximum colony size
  • Growth: Moderate, inferred from tropical Polyrhachis patterns
  • Development: Unknown, no specific study exists for this species (Development time is estimated based on related tropical Formicinae species, but exact data is lacking.)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical habitat inference. A temperature gradient helps ants self-regulate.
  • Humidity: Keep nest substrate consistently moist but not waterlogged, inferred from tropical forest habitat.
  • Diapause: No, as a tropical species, they do not require hibernation. Keep temperatures stable year-round.
  • Nesting: Inferred from genus patterns, prefer tight, enclosed spaces like rotting wood or cavities. In captivity, use Y-tong or naturalistic setups with moist substrate.
• Behavior: Based on genus patterns, workers are moderately active and calm in temperament. They use spines for defense and are not highly aggressive. Escape risk is moderate due to medium size, standard prevention measures are sufficient.
• Common Issues: mold can develop if humidity is too high and ventilation poor, balance moisture and airflow, wild-caught colonies may carry parasites that harm the colony in captivity, temperature drops below 22°C can slow brood development, queens may need protein access during founding if semi-claustral, but this is unconfirmed

Nest Preferences

Polyrhachis cybele naturally nests in rotting wood, under bark, or in cavities in tropical forests ^[3]. In captivity, they do well in Y-tong nests or naturalistic setups that mimic these conditions. They prefer snug chambers rather than spacious ones. Use damp soil or coco fiber as substrate to retain moisture. Avoid dry setups, they need some humidity.

Feeding and Diet

In the wild, Polyrhachis ants are omnivorous, feeding on honeydew, small insects, and nectar ^[3]. In captivity, offer sugar water or honey constantly, and protein like mealworms or fruit flies twice weekly. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Care

As a tropical species, keep temperatures around 24-28°C for optimal care. Use a heating cable on one side of the nest to create a gradient. Room temperature alone may be too cool and slow growth.

Behavior and Temperament

Workers are day-active foragers with a calm temperament. They use spines for defense when threatened. Escape risk is moderate, use Fluon barriers on formicaria rims.

Colony Founding

Founding behavior is unconfirmed for this species. Based on genus patterns, queens may be semi-claustral and need protein access during founding. Provide a small hunting area with prey items like fruit flies.

Growth and Development

Colony growth is moderate. Brood development time is unknown, but tropical species typically develop faster than temperate ones. Feed regularly and maintain stable conditions for healthy growth.
