Myopias chapmani

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Wet rain forest along creeks in Queensland, Australia, specifically in areas like Blackall Range near Montville. Nests in rotting wood fragments on the ground ^[1].
• Colony Type: Polygyne, multiple queens per colony, as documented in the type colony with two dealate queens and up to 30 workers ^[1].
• Size & Growth:
  • Queen: ~5.2 mm (dealate) ^[1]
  • Worker: ~5.2-5.7 mm ^[1]
  • Colony: Up to 30 workers based on type colony ^[1]
  • Growth: Moderate, inferred from small colony size and Ponerine development patterns
  • Development: Estimated 6-10 weeks at optimal temperature, based on typical Ponerine patterns (Direct development data unavailable, keep warm for faster development)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, with a gentle gradient to allow self-regulation ^[1].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, mimicking wet rainforest conditions ^[1].
  • Diapause: No true diapause likely, as species is from subtropical Queensland, may show reduced activity in cooler months ^[1].
  • Nesting: Naturalistic setups with rotting wood or cork work well, as they nested in rotten branches in the wild. Y-tong or plaster nests with moisture chambers are also suitable ^[1].
• Behavior: Predatory ants that hunt small invertebrates. Workers are moderately active foragers with a functional sting for defense, typical of Ponerinae. Escape risk is moderate due to medium size, use standard barrier methods. Queens are similar in size to workers, which is documented for this species ^[1].
• Common Issues: small colony size means losses have bigger impact, keep colonies stable, predatory diet requires live prey, ensure consistent small invertebrate food sources, high humidity needs can lead to mold if ventilation is poor, multiple queens may cause tension if disturbed, handle gently, rainforest origin means they are sensitive to drying out

Housing and Nest Setup

You can set up Myopias chapmani in naturalistic environments that mimic their rotting wood habitat. Use cork or rotting wood pieces, as they nested in a thick fragment of a rotten branch in the wild ^[1]. Y-tong nests with appropriately sized chambers or plaster nests that hold moisture well are also suitable. Provide a humid environment with damp substrate, and avoid too much open space since colonies are small. A small outworld for foraging completes the setup.

Feeding and Diet

You need to offer live invertebrate prey, as these ants are predatory. Provide small live prey like fruit flies, pinhead crickets, or small mealworms 2-3 times per week, adjusting based on consumption. Remove uneaten prey after 24 hours to prevent mold. Sugar water or honey can be offered occasionally, but protein-rich live prey should be the primary food source ^[1].

Temperature and Humidity

Keep your colony at 24-28°C, mimicking the warm Queensland rainforest. Use a heating cable on one side to create a temperature gradient. Humidity is critical, maintain damp substrate in the nest area, as their natural habitat is wet rain forest along creeks ^[1]. Mist regularly or use a water reservoir, but ensure good ventilation to prevent mold.

Colony Structure and Behavior

This is a polygyne species, so you can keep multiple queens together, as documented in the type colony with two dealate queens and up to 30 workers ^[1]. Colony size remains small, likely under 100 workers. Workers are moderately aggressive predators with a functional sting for defense. Avoid disturbing the colony too much, as polygyne colonies can be sensitive to stress.

Growth and Development

Colony growth is moderate but steady. Queens are dealate and about 5.2 mm, similar to workers ^[1]. Development from egg to worker likely takes several weeks at optimal temperature, following typical Ponerine patterns. Nanitics (first workers) will be functional. Since colonies stay small, growth may seem slow compared to faster-growing genera.
