Odontomachus infandus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Endemic to the Philippines, found on Luzon and Mindoro in shaded, humid forest habitats ^[1].
• Colony Type: Colony structure is unconfirmed, but based on Odontomachus patterns, likely monogyne (single queen).
• Size & Growth:
  • Queen: Up to 16.13 mm total length ^[1]
  • Worker: Up to 16.57 mm total length ^[1]
  • Colony: Size data unavailable
  • Growth: Moderate, estimated from tropical habitat
  • Development: Unknown, no specific data available (Development likely faster in tropical conditions.)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical habitat.
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as humidity is a main requirement in their natural habitat ^[1].
  • Diapause: No, tropical species do not require hibernation.
  • Nesting: Use Y-tong or plaster nests that retain moisture, connected to an outworld for foraging.
• Behavior: Trap-jaw ants are active predators that hunt insects using their snap-jaw mandibles. They can deliver a painful sting if threatened, with venom LD50 of 33 mg/kg ^[2]. They are moderate escape artists due to their size.
• Common Issues: mold can develop if humidity is too high and ventilation poor, balance airflow carefully., their powerful mandibles can snap through cotton plugs, use secure barriers like fluon., they need live prey regularly, sugar water alone is insufficient ^[1]., temperature drops below 22°C can be harmful, keep them warm., wild-caught colonies may have parasites, quarantine if possible.

Housing and Nest Setup

Odontomachus infandus needs housing that retains moisture. Use Y-tong (AAC) or plaster nests, as these materials hold humidity which is critical for this species ^[1]. Connect the nest to an outworld for foraging. Ensure nest chambers are sized for their large workers, with passages wide enough for movement but not excessively large. Escape prevention is important, use fluon barriers on the rim of the outworld.

Feeding and Diet

As predatory trap-jaw ants, they need a protein-rich diet of live insects. Offer small prey like fruit flies, crickets, or mealworms ^[1]. They use their powerful mandibles to capture prey. Sugar water can be offered occasionally, but live prey is essential ^[1].

Temperature and Humidity

These are tropical ants, so keep temperatures warm, roughly 24-28°C. Humidity is a main requirement in their natural habitat, keep the nest substrate consistently moist but not waterlogged ^[1].

Behavior and Defense

Workers are active hunters that use trap-jaw mandibles to capture prey. They can sting if threatened, with venom LD50 of 33 mg/kg ^[2]. They are not typically aggressive but will defend themselves. Workers are ground-dwelling and forage in the outworld.

Colony Development

Founding behavior is unconfirmed. Colony growth is moderate, but specific development timelines are unknown. Maintain warm conditions year-round to support brood development.
