Pheidole terresi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Hispaniola island (Haiti and Dominican Republic). Found in dry forest and pine-hardwood forested ravines, nesting in soil under rocks and downed wood at elevations from 92-2,090m ^[4][1][2].
• Colony Type: Unconfirmed, no specific data on queen number for this species.
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements in research context.
  • Worker: Size data unavailable, no total length measurements in research context.
  • Colony: Unknown, based on Pheidole genus, colonies can grow to thousands of workers, but no specific data for this species.
  • Growth: Moderate, estimated from genus patterns.
  • Development: 6-8 weeks, estimated based on typical Pheidole development at warm temperatures ^[3]. (Development time is estimated from genus-level data since specific studies are lacking for this species.)
• Antkeeping:
  • Temperature: Keep warm, around 24-28°C. Being from tropical Hispaniola, they benefit from stable warmth. A heating cable on one side of the nest creates a suitable gradient ^[1][2].
  • Humidity: Keep the nest substrate consistently moist but not waterlogged. Provide a moisture gradient ^[1][2].
  • Diapause: Unknown, no specific data on diapause for this species.
  • Nesting: Soil-based nests work well. A naturalistic setup with moist substrate or a Y-tong/plaster nest with a water reservoir maintains humidity ^[1][2].
• Behavior: Pheidole terresi is not particularly aggressive but will defend the nest if threatened. Escape risk is moderate, standard barriers are necessary ^[3].
• Common Issues: temperature management is critical, being tropical, they suffer in cool conditions ^[1][2]., wild-caught colonies may carry parasites or diseases from their native habitat., colonies may be slow to establish compared to more common species.

Housing and Nest Preferences

Pheidole terresi does well in soil-based naturalistic setups that mimic their natural nesting preferences. In the wild, they nest in soil under rocks and downed wood ^[1][2]. A Y-tong or plaster nest with a water reservoir also works well to maintain consistent humidity. Place the nest in a warm area (around 24-28°C) with minimal disturbance during the founding stage.

Feeding and Diet

Pheidole terresi is an omnivore that accepts seeds and small protein sources. Offer seeds like grass seeds or millet as a primary food, and protein from small insects like fruit flies or mealworms 2-3 times per week. Remove uneaten prey within 24 hours to prevent mold.

Temperature and Seasonal Care

Maintain nest temperatures between 24-28°C to support normal activity and brood development. A heating cable on one end of the nest creates a gradient. Unlike temperate species, they do not require true hibernation, but a slight cool-down may be optional.

Colony Establishment and Growth

A newly mated queen will dig a chamber and seal herself inside, but founding behavior is unconfirmed for this species. After 4-6 weeks, first workers may emerge. Colony growth is moderate, with majors appearing after several dozen workers.

Behavior and Defense

Pheidole terresi has minor workers for foraging and brood care, while majors defend the colony. They are not aggressive toward keepers but will mobilize majors if threatened. Their stingers are present but not dangerous to humans. Escape risk is moderate due to their size.
