Pheidole scrobifera

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the Neotropical region, Costa Rica, Honduras, Nicaragua, and Panama. Found on the Atlantic slope of Costa Rica up to 900m elevation in mature wet forests, nesting in rotten logs and decaying wood ^[1][2].
• Colony Type: Colony structure is unconfirmed. No specific data on queen number for this species.
• Size & Growth:
  • Queen: Size data unavailable
  • Worker: Size data unavailable
  • Colony: Unknown, no colony size data available
  • Growth: Unknown, no development studies available
  • Development: Unconfirmed, no direct measurements. Based on typical Pheidole patterns, expect 6-10 weeks at tropical temperatures ^[1]. (Development timeline is unconfirmed. Related Pheidole species typically develop in 6-10 weeks under warm conditions.)
• Antkeeping:
  • Temperature: Keep warm, around 24-28°C. This species comes from tropical wet forests where temperatures are consistently warm ^[1].
  • Humidity: Keep nest substrate consistently moist but not waterlogged, as they inhabit wet forests ^[1].
  • Diapause: No, tropical species do not require hibernation ^[1].
  • Nesting: In nature, they nest in rotting wood and soil. In captivity, use humidified nests like Y-tong or plaster, with tight chambers scaled to their small size ^[2][1].
• Behavior: Nocturnal foragers, workers become active after dark ^[2][1]. Not aggressive toward keepers but will defend nest if disturbed. Escape risk is high due to small worker size, use effective barriers.
• Common Issues: drying out is a common problem due to high humidity needs, monitor substrate moisture regularly., escape risk is high due to small worker size, ensure barriers are effective., cold temperatures can slow or stop brood development, maintain warm temperatures year-round.

Natural History and Distribution

Pheidole scrobifera is found across Central America, specifically in Costa Rica, Honduras, Nicaragua, and Panama. They inhabit the Atlantic slope of Costa Rica up to 900 meters elevation in mature wet forests. These ants nest in rotting wood and soil on the forest floor, and workers forage at night ^[1][2].

Housing and Nest Setup

In captivity, recreate their natural forest floor environment. Use humidified artificial nests like Y-tong or plaster, with tight chambers for their small size. Provide a water source and maintain high humidity to mimic wet forest conditions ^[2][1].

Feeding and Diet

Pheidole scrobifera are generalist foragers. Offer a varied diet including small seeds, grain, and protein sources like fruit flies or small insects. Provide sugar water or honey occasionally. Feed every 2-3 days and remove uneaten food to prevent mold ^[1].

Temperature and Seasonal Care

As a tropical species, keep temperatures between 24-28°C year-round. No hibernation is needed. If room temperature is below this range, use a heating cable to create a warm gradient ^[1].

Behavior and Observation

These ants are nocturnal, so most activity occurs after dark. They have major and minor worker castes, with majors defending the nest. They are not aggressive but will protect their home if disturbed ^[2][1].
