Polyrhachis narendrani

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Endemic to Kerala, India, in disturbed areas with small plants and trees ^[1][2].
• Colony Type: Unconfirmed. Based on genus patterns, likely monogyne (single-queen colonies), but no species-specific data exists.
• Size & Growth:
  • Queen: Unknown, no data available
  • Worker: Approximately 6.2 mm total length ^[1]
  • Colony: Unknown, no wild colony data available
  • Growth: Unknown, no development data exists
  • Development: Unknown, no direct measurements. Based on typical Polyrhachis patterns, expect 6-10 weeks from egg to worker in warm conditions (Development likely depends on temperature and food availability)
• Antkeeping:
  • Temperature: Keep at 24-28°C. Inferred from tropical habitat
  • Humidity: Provide a moist nest substrate with a humidity gradient. Inferred from tropical habitat
  • Diapause: Unlikely required. Tropical species from Kerala probably do not experience cold winters
  • Nesting: Natural nesting unconfirmed. Many Polyrhachis species are arboreal or ground-nesting. Use a Y-tong or plaster nest with moderate moisture
• Behavior: Behavior unstudied. Based on genus patterns, Polyrhachis ants are moderate foragers with some aggression when defending nests. Escape risk is moderate due to size. Defense mechanism: lacks a functional sting but can spray formic acid from an acidopore, typical of Formicinae
• Common Issues: lack of species-specific care data may lead to trial and error, tropical species sensitive to temperature drops or dry conditions, escape prevention needed despite medium size, feeding preferences unknown, may require experimentation, limited availability in the antkeeping hobby

Appearance and Identification

Polyrhachis narendrani workers are about 6.2 mm in total length. The body is black, including the head, thorax, and gaster, while the legs are reddish. Distinctive features include two long forward-pointing spines on the pronotum, spiny legs, and a petiolar node with two long curved spines. The body has a shining appearance with silky silvery hairs ^[1].

Distribution and Habitat

This species is endemic to Kerala, India, and was collected from a disturbed area with small plants and trees in Palode, Thiruvananthapuram ^[1][2]. Kerala has a tropical monsoon climate, suggesting adaptation to warm, humid conditions.

Nest Preferences and Housing

Natural nesting behavior is unconfirmed. Many Polyrhachis species nest in trees or under stones. For captivity, use a Y-tong or plaster nest with moderate moisture. Provide a humidity gradient to allow ants to regulate moisture levels.

Feeding and Diet

Diet is unconfirmed. Most Polyrhachis species are omnivorous, feeding on honeydew, nectar, and small insects. Offer sugar water or honey as a constant energy source and protein like small crickets or mealworms. Remove uneaten food promptly to prevent mold.

Temperature and Seasonal Care

Keep temperatures at 24-28°C. As a tropical species, diapause is unlikely. Maintain stable conditions year-round. Use a heating mat if room temperature falls below 24°C.

Behavior and Temperament

Specific behavior is unstudied. Based on genus patterns, workers are moderate foragers and may show aggression when defending the nest. Escape prevention is important due to medium size. Defense involves spraying formic acid, typical of Formicinae.
