Paratrachymyrmex levis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Northern South America, tropical forest regions ^[1]
• Colony Type: Colony structure is unconfirmed. Based on related Trachymyrmex species, likely single-queen colonies.
• Size & Growth:
  • Queen: size data unavailable
  • Worker: size data unavailable
  • Colony: Up to several hundred workers, estimated from related Trachymyrmex species
  • Growth: Moderate
  • Development: Estimated 6-10 weeks at tropical temperatures based on related Trachymyrmex species (Fungus-growing ants typically have slower development due to the time needed to establish a fungal garden)
• Antkeeping:
  • Temperature: Keep at 24-28°C, tropical ants require warm, stable conditions. Use a heating cable if needed.
  • Humidity: Keep the nest substrate consistently moist but not waterlogged to support the fungal cultivar.
  • Diapause: No, these are tropical ants that do not require hibernation ^[1].
  • Nesting: Y-tong (AAC) or plaster nests work well. Provide a humidity gradient with a water reservoir to maintain moisture.
• Behavior: Workers are small and active, foraging for organic material to cultivate their fungus. They are docile and rarely sting. Escape prevention should be moderate due to their small size.
• Common Issues: fungal garden collapse is the biggest risk, if the fungus dies, the colony starves. maintain consistent humidity and avoid contamination., tropical humidity requirements can be challenging, dry conditions quickly kill the fungal cultivar., slow growth compared to generalist ants, keepers may overfeed while waiting for development, leading to mold problems., limited accepted foods, they are specialized fungus farmers and may not accept typical ant foods., temperature drops below 22°C can stress the colony and fungal cultivar.

Fungus Farming - The Key to Their Care

Paratrachymyrmex levis belongs to the fungus-growing ant group (Attini), which includes leaf-cutter ants. Unlike leaf-cutters that harvest fresh leaves, Paratrachymyrmex collects organic debris like dead leaves, fruit scraps, and flower petals to feed their fungal cultivar. The ants tend the fungus in special nest chambers and consume the fungal mycelium as their primary food source. This obligate relationship means you must provide organic material for the fungus, not direct food for the ants. Without their fungus, the colony cannot survive ^[1].

Feeding and Nutrition

Feeding Paratrachymyrmex levis requires providing organic material for the fungal garden. Offer small pieces of dead leaves, ripe fruit, flower petals, or grass clippings. The ants will process this and add it to their fungus. Remove uneaten material before it molds to prevent contamination. Some keepers offer small amounts of honey or sugar water sparingly, but protein is typically not needed. Maintain hygiene to avoid mold, which can kill the fungal cultivar.

Housing and Nest Setup

Use Y-tong (AAC) or plaster nests for Paratrachymyrmex levis, as they hold humidity well. The nest should have multiple chambers for fungus cultivation and brood areas. Connect a water reservoir via cotton wick to maintain moisture. The outworld should be simple with easy access for adding organic material. Escape prevention is moderate, use fluon barriers on the outworld rim. A test tube setup works for founding colonies, but move to a proper nest once the colony grows.

Temperature and Humidity Management

As tropical ants from northern South America, Paratrachymyrmex levis requires warm, humid conditions year-round. Keep the nest at 24-28°C using a heating cable if room temperature is lower. Temperature stability is important, avoid fluctuations. Humidity should be maintained through a moist substrate and water reservoir, check daily to ensure it is moist but not waterlogged. Never let the nest dry out completely, as the fungal cultivar will die quickly. ^[1]

Growth and Development

Fungus-farming ants develop more slowly than typical ants due to fungal garden establishment. Expect first workers to emerge 6-10 weeks after founding at tropical temperatures. The queen initially tends brood and fungus alone, workers later take over fungus maintenance. Colony growth is moderate, reaching several hundred workers may take a year or more. The key milestone is a healthy, growing fungal garden.
