Polyrhachis templi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Asia-Pacific region. This species nests in subterranean chambers or within rotting wood in forested areas ^[1][2].
• Colony Type: Colony structure is not well documented for P. templi. Based on typical Polyrhachis patterns, colonies are likely monogyne (single queen), but this is not confirmed.
• Size & Growth:
  • Queen: Size data unavailable from research context.
  • Worker: Size data unavailable from research context.
  • Colony: Up to several hundred workers at maturity, estimated from related species.
  • Growth: Moderate
  • Development: Estimated 6-10 weeks at tropical temperatures, based on genus patterns. (Development time is estimated from related species since specific data is not available. Cocooned pupae may extend development slightly.)
• Antkeeping:
  • Temperature: Keep the nest area warm, as this species is from tropical regions. Specific temperature requirements are not confirmed, but maintaining warmth around 25-28°C is typical for tropical ants.
  • Humidity: Keep the nest substrate consistently moist but not waterlogged, based on their natural nesting preferences ^[1][2].
  • Diapause: No, as a tropical species, they do not require hibernation. This is inferred from their geographic range.
  • Nesting: Provide nests that mimic natural habitat, such as Y-tong or plaster nests with moist chambers. They prefer subterranean or lignicolous nesting ^[1][2].
• Behavior: Polyrhachis templi is generally calm based on genus patterns. Workers are active foragers. Their spiny appearance serves as physical defense, and they can spray formic acid as a defense mechanism (typical for Formicinae). Escape risk is moderate due to their size.
• Common Issues: colonies may struggle if temperatures drop too low, as they are tropical species., humidity must be maintained to prevent dry conditions, which can harm the colony., slow founding phase requires patience, as queens may take time to raise first workers., cocooned pupae require stable conditions, disturbance can cause issues ^[1][2]., wild-caught colonies may carry parasites that can devastate captive colonies.

Nest Preferences and Housing

Polyrhachis templi naturally nests in subterranean chambers or within rotting wood ^[1][2]. In captivity, they do well in Y-tong formicariums with dirt chambers, plaster nests with moisture chambers, or naturalistic setups. The key is providing moist substrate conditions, they prefer their nest material to be damp but not waterlogged. A multi-chamber setup works well, allowing the colony to distribute brood across different humidity zones. If using a naturalistic setup, include pieces of rotting wood or cork bark buried in moist soil. The nest should have narrow passages between chambers, as these ants feel secure in snug spaces. Avoid very dry environments or nests that dry out quickly.

Feeding and Diet

Polyrhachis templi is an omnivorous species that accepts a variety of foods. In captivity, offer protein sources such as small insects (fruit flies, small crickets, mealworms), and provide sugar sources like honey water or sugar water regularly. They will also eat small amounts of seeds or other organic matter. Feed them small prey items appropriate to their worker size, they can handle prey roughly equal to their own body size. Offer protein 2-3 times per week, and keep a sugar source available at all times. Remove uneaten prey after 24-48 hours to prevent mold issues. Fresh water should always be available.

Temperature and Seasonal Care

As a tropical species, Polyrhachis templi requires warm temperatures. Keep the nest area warm, and provide a temperature gradient using a heat source. Specific needs are not confirmed in research, but maintaining warmth around 25-28°C is common for tropical ants. Temperatures below 22°C can slow colony growth significantly, and prolonged cool conditions may harm the colony. Use a heating cable or heat mat on one side of the nest to create a temperature gradient, this allows ants to move between warmer and cooler areas as needed. Monitor with a thermometer placed near the nest. Unlike temperate species, they do not require a winter rest period. Maintain consistent warmth throughout the year to support continuous colony growth.

Behavior and Colony Dynamics

Polyrhachis templi workers are active and curious foragers. They establish chemical trails to food sources and will recruit nestmates efficiently. The spiny projections on their bodies serve as a defense mechanism, when threatened, they can wedge themselves into crevices using these spines, making them difficult to extract. Their primary defense is spraying formic acid, typical for Formicinae. They are generally peaceful toward keepers and rarely display aggressive behavior unless their nest is directly threatened. Workers have moderate longevity compared to other ant species. The colony will expand gradually, with the queen producing workers continuously once established. Brood development should be visible within weeks of founding, look for eggs, then larvae, then cocooned pupae developing in sequence.
