Melophorus dicyrtos

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Northern Australia (Torresian zone: NT, QLD, WA). Found in eucalyptus savannah, eucalypt woodland, and closed woodland/forest ^[1].
• Colony Type: Colony structure is unconfirmed for this species.
• Size & Growth:
  • Queen: Size data unavailable, no documented queen measurements for this species.
  • Worker: Minor workers: approximately 0.66-1.28mm head width. Major workers: approximately 1.25mm+ head width. Full body length data is unavailable ^[1].
  • Colony: Maximum colony size is unconfirmed for this species.
  • Growth: Growth rate is unconfirmed.
  • Development: Development time is unconfirmed for this species. (Specific development data for M. dicyrtos is not available.)
• Antkeeping:
  • Temperature: Keep at 24-30°C. As a tropical Australian species from the Torresian zone, they prefer warm conditions. A heating cable on one side of the nest can create a gradient.
  • Humidity: Moderate humidity around 50-70%. They inhabit savannah and woodland areas, not rainforest. Allow the nest substrate to dry slightly between water additions.
  • Diapause: Likely minimal or no true diapause. As a tropical species from northern Australia, they probably remain active year-round with reduced activity during dry seasons.
  • Nesting: In captivity, they do well in Y-tong (AAC) nests, plaster nests, or test tube setups. Provide small chambers scaled to their worker size. They may accept naturalistic setups with soil substrates.
• Behavior: Melophorus dicyrtos workers have been collected in flight intercept traps, suggesting they climb vegetation, this indicates they are active foragers rather than strictly ground-nesting ^[1]. They are generalist foragers, similar to other Melophorus species that scavenge and tend honeydew. The species is not known to be particularly aggressive. Escape prevention should be moderate, workers are small so standard barrier methods like Fluon on test tube rims work well.
• Common Issues: limited documented care information for this species makes successful keeping more challenging, wild-caught colonies may have parasites or diseases that affect survival in captivity, dry season care is not well understood, may need humidity adjustments, queen founding behavior is unconfirmed, may require specific conditions, limited availability means established colonies are rare in the hobby

Housing and Nest Setup

Melophorus dicyrtos can be kept in standard ant keeping setups including test tubes, Y-tong (AAC) nests, or plaster formicaria. Since workers are small, ensure escape prevention is adequate, use fine mesh and apply Fluon or similar barriers to container rims. Provide a small outworld for foraging. The ants have been found in various Australian woodland habitats, so a naturalistic setup with a soil substrate can work well. However, they are not difficult to keep in simpler setups. Ensure the nest has some chambers scaled to the major workers. ^[1]

Feeding and Diet

Melophorus species are generalist foragers that typically scavenge and tend honeydew from aphids and scale insects. In captivity, offer sugar water or honey as an energy source, along with protein-rich foods like small insects (fruit flies, pinhead crickets, mealworms). They likely accept a wide variety of foods. Feed protein 2-3 times per week and provide sugar water constantly. Remove uneaten prey after 24-48 hours to prevent mold. ^[1]

Temperature and Heating

As a tropical Australian species from the Torresian phytogeographic zone (northern Australia), Melophorus dicyrtos prefers warm conditions. Keep nest temperatures between 24-30°C. A heating cable placed on one side of the nest creates a temperature gradient allowing the ants to self-regulate. Avoid temperatures below 20°C for extended periods. Room temperature may be sufficient in warm climates, but supplemental heating is recommended for optimal colony health and growth. ^[1]

Humidity and Water

Melophorus dicyrtos inhabits eucalyptus savannah and woodland areas in northern Australia, which have distinct wet and dry seasons. Maintain moderate humidity around 50-70%. The nest substrate should be allowed to dry partially between water additions, these ants are not rainforest dwellers and do not need constantly saturated conditions. Provide a water tube in the outworld for drinking access. ^[1]

Behavior and Foraging

Workers have been collected in flight intercept traps, suggesting Melophorus dicyrtos climbs vegetation to forage rather than remaining strictly ground-dwelling ^[1]. This indicates active, mobile foraging behavior. The species is not known to be particularly aggressive. They likely use chemical trails to recruit nestmates to food sources, similar to other Melophorus species.

Colony Development

The colony structure of M. dicyrtos has not been directly studied. Colony size data is unavailable for this species. Development time from egg to worker is unconfirmed. Colonies probably grow moderately once established, with nanitics (first workers) being smaller than subsequent generations. ^[2][1]
