Dolichoderus goudiei

Quick Summary

• Difficulty: Medium
• Origin & Habitat: South-eastern Australia (ACT to south-eastern South Australia) in dry sclerophyll and savannah woodlands ^[1][3]
• Colony Type: Based on Dolichoderus patterns, likely monogyne (single queen colonies)
• Size & Growth:
  • Queen: Unconfirmed, likely around 4-5 mm based on Dolichoderus genus patterns
  • Worker: Body size data unavailable, inferred from Dolichoderus genus to be approximately 2-3 mm
  • Colony: Unknown for this species
  • Growth: Moderate, inferred from small size and genus patterns
  • Development: Estimated 6-10 weeks at optimal temperature based on related Dolichoderus species (Development timeline not directly studied, estimates based on genus patterns)
• Antkeeping:
  • Temperature: Keep at room temperature, roughly 22-26°C, based on their temperate range
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as they nest in soil under rocks or in rotten wood ^[3]
  • Diapause: Likely required for temperate species, provide 2-3 months at reduced temperatures during winter
  • Nesting: Soil-nesting species, prefer nests with moist soil and hiding spots like rocks or rotten wood ^[3]
• Behavior: These ants are diurnal and form distinct foraging columns on the ground and vegetation. They are general scavengers with a strong preference for honeydew from aphids ^[3]. Workers are small but agile, and while not aggressive, they may bite if threatened. Their tiny size means escape prevention is critical ^[2].
• Common Issues: tiny size means escapes are likely without fine mesh barriers and tight-fitting lids, slow founding, queens may take months to produce first workers, patience is essential, colonies can be slow to grow, which may lead to overfeeding or excessive disturbance, wild-caught colonies may carry parasites that can devastate captive colonies, dry conditions will cause colony decline, monitor substrate moisture regularly

Housing and Setup

For a newly caught queen, a simple test tube setup works well. Fill a test tube about one-third with water, plug the water end with a cotton ball, and place the queen in the dry portion. This maintains humidity while reducing stress. Once workers emerge, you can continue in the test tube or transition to a small formicarium. Because these ants are tiny, any formicarium should have small chambers and narrow passages scaled to their size. A naturalistic setup with moist soil and a piece of flat stone or rotten wood on top mimics their natural nesting under rocks in soil ^[3]. Always use excellent escape prevention: apply fluon to rim edges and use fine mesh on ventilation holes.

Feeding and Diet

In the wild, Dolichoderus goudiei are general scavengers but strongly prefer honeydew from aphids and other Hemiptera ^[3]. In captivity, offer sugar water or honey diluted 50/50 with water constantly. For protein, provide small prey like fruit flies or pinhead crickets 2-3 times per week. Remove uneaten food after 24 hours to prevent mold. Fresh water should always be available.

Temperature and Seasonal Care

Maintain temperatures around 22-26°C for optimal development, based on their temperate range. During winter, consider a diapause period at 10-15°C for 2-3 months to mimic natural cycles. Reduce feeding during this period.

Colony Founding

Founding behavior is unconfirmed for this species. Do not disturb a founding queen, as stress can cause her to eat eggs. After nanitics emerge, ensure food is available but avoid overfeeding.

Behavior and Observation

These ants are diurnal and form foraging columns, following pheromone trails to food sources ^[3]. They are active during daylight hours and show a preference for sweet liquids. Their small size requires careful handling to avoid crushing them.
