Dorymyrmex carettei

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Central Argentina, including the Caldenal district and Santiago del Estero regions, in grassland and forest edge habitats ^[2][3].
• Colony Type: Unconfirmed, no specific data on queen number or social structure.
• Size & Growth:
  • Queen: ~6-8 mm (inferred from Dorymyrmex genus) ^[1]
  • Worker: ~3-5 mm (inferred from Dorymyrmex genus) ^[1]
  • Colony: Up to several hundred workers (inferred from Dorymyrmex patterns) ^[1]
  • Growth: Moderate
  • Development: Estimated 6-8 weeks at optimal temperature (inferred from related Dolichoderinae species) ^[1] (Development time may vary with temperature, specific timing for this species unconfirmed.)
• Antkeeping:
  • Temperature: Keep at 22-26°C, inferred from temperate Argentine distribution ^[1].
  • Humidity: Keep substrate consistently moist but not waterlogged, inferred from ground-nesting habits ^[1].
  • Diapause: Yes, likely required for 2-3 months at 10-15°C in winter, based on genus patterns ^[1].
  • Nesting: Ground-nesting, use soil or plaster nests in captivity, mimicking natural habits ^[1].
• Behavior: Workers are active foragers, not aggressive, and typically flee when disturbed. They use chemical defense secretion from the abdomen. Escape risk is moderate due to small worker size, ensure barriers are secure.
• Common Issues: colonies may be slow to establish during founding, patience is needed, escape prevention is important due to small worker size, winter dormancy is often required but timing can vary by colony origin, wild-caught colonies may harbor parasites affecting survival, overheating can be more dangerous than slight underheating

Housing and Nest Setup

Dorymyrmex carettei does well in standard ant housing. For founding colonies, a test tube setup works fine, fill one end with water reservoir and use cotton to create a humid chamber. Once the colony reaches 20-30 workers, you can move them to a formicarium. A naturalistic setup with a soil chamber works well since these are ground-nesting ants ^[1]. Use a nesting area of at least 10x10cm with small chambers scaled to their 3-5mm worker size. The outworld should have a small foraging area for food placement. Ensure the nest maintains moderate humidity, allow partial drying between waterings ^[1].

Feeding and Diet

Dorymyrmex carettei is omnivorous. Offer sugar sources like sugar water or honey constantly, and protein prey such as fruit flies or small crickets 2-3 times per week ^[1]. In the wild, they forage for honeydew and small arthropods. Remove uneaten prey after 24-48 hours to prevent mold. Workers share food through trophallaxis.

Temperature and Seasonal Care

Keep your colony at 22-26°C for optimal development. During winter, allow a natural slowdown by moving the colony to a cooler location (10-15°C) for 2-3 months to mimic diapause ^[1]. Adjust based on colony response if origin is from warmer regions.

Colony Development

A newly mated queen may seal herself in a chamber for founding, but this behavior is unconfirmed for this species. The first workers (nanitics) will begin foraging to support growth. Expect 6-8 weeks from egg to first worker at warm temperatures, though this is estimated ^[1]. Growth is moderate, with colonies reaching up to several hundred workers over time.

Behavior and Observation

Workers are active foragers, patrolling the outworld for food. They are relatively docile and flee when disturbed, using chemical defense secretion from the abdomen ^[1]. Escape prevention is important due to small size, use barriers on nest rims. They are diurnal and most active during warmer hours.
