Polyrhachis cubaensis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Eastern and southern Africa in savannah woodland and forest edge habitats, nesting in hollow stems and galls ^[2][3].
• Colony Type: Colony structure is not well documented. Based on typical Polyrhachis patterns, they likely form single-queen colonies, but this is unconfirmed for this species.
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements found in research. Inferred from Polyrhachis genus patterns as approximately 9-11 mm.
  • Worker: 6.4-7.5 mm ^[1]
  • Colony: Unknown from available research, likely reaches several hundred workers based on genus patterns
  • Growth: Moderate, inferred from genus patterns
  • Development: Estimated 8-12 weeks at optimal temperature based on related Polyrhachis species development patterns (Development time is inferred from genus-level data since species-specific measurements are unavailable.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. Based on their savannah habitat, they prefer warm conditions. Use a heating cable on one side to create a gradient ^[3].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, with a humidity gradient. Their natural habitat experiences seasonal variation, so they tolerate drier conditions ^[3].
  • Diapause: Unknown, no specific data on diapause for this species. Based on genus patterns, a mild winter rest period may be beneficial if activity reduces.
  • Nesting: Lignicolous species that nest in wood. Use Y-tong, wooden formicaria, or test tube setups with wood elements. Provide twigs or hollow decorations for nesting sites ^[3].
• Behavior: Generally docile and non-aggressive. Workers are active foragers but not prone to biting. They lack a functional sting and spray formic acid as a defense mechanism (subfamily Formicinae trait). Escape risk is moderate due to their size, use barriers like Fluon on container rims. They are primarily arboreal, foraging in trees and shrubs ^[3].
• Common Issues: wood-nesting requirements mean standard soil formicaria may not be ideal, provide appropriate nesting options., escape prevention is important despite moderate size, they can fit through small gaps., slow growth may frustrate beginners expecting rapid colony development., limited availability in the antkeeping hobby means established colonies may be difficult to obtain.

Housing and Nest Preferences

Polyrhachis cubaensis is a lignicolous species that nests in wood and plant stems. In captivity, use Y-tong nests, wooden formicaria, or test tube setups with wood elements. Provide enclosed spaces that mimic hollow stems, such as twigs or cork bark. They may line nests with silk webbing ^[3]. Avoid fully soil-based formicaria unless wood structures are included.

Feeding and Diet

Feed P. cubaensis small insects like fruit flies or mealworms 2-3 times per week, and provide sugar water or honey water continuously. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Seasonal Care

Maintain nest temperatures between 24-28°C for optimal brood development. Use a heating cable on one side to create a gradient. If activity reduces in winter, consider a mild rest period at 15-18°C for 2-3 months, though this is not required in stable environments.

Behavior and Handling

Workers are docile and active foragers. They spray formic acid as a defense but rarely bite keepers. Use barriers like Fluon to prevent escapes, as they can fit through small gaps. They are arboreal and climb well.
