Pristomyrmex schoedli

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Tropical Philippines, specifically Leyte island. Found in lowland areas near rivers and streams at 50-100m elevation, nesting in fallen logs and decaying wood ^[1][2].
• Colony Type: Colony structure is unconfirmed. Wild colonies have been observed with up to 100 workers, suggesting smaller colony sizes ^[1].
• Size & Growth:
  • Queen: size data unavailable
  • Worker: ~3.4-4.4 mm ^[1]
  • Colony: Up to 100 workers ^[1]
  • Growth: Unknown
  • Development: Estimated 6-8 weeks based on typical Myrmicinae patterns (Development may vary with temperature, no species-specific data exists.)
• Antkeeping:
  • Temperature: Keep warm year-round around 24-28°C, reflecting their tropical origin ^[2].
  • Humidity: Keep the nest substrate consistently moist but not waterlogged, as they naturally inhabit damp, decaying wood near streams ^[1][2].
  • Diapause: No, tropical species do not require hibernation ^[2].
  • Nesting: Use Y-tong, plaster, or naturalistic setups with decaying wood pieces. They naturally nest in fallen logs, so include wood fragments to mimic their environment ^[1].
• Behavior: Workers are diurnal foragers, active on leaves during the day ^[1]. They are not aggressive and lack a painful sting, their defense involves smearing venom, typical of Myrmicinae. Their small size (3-4mm) makes escape prevention critical ^[1].
• Common Issues: escape prevention is critical due to tiny size, use fine mesh and tight-fitting lids, small colonies are sensitive to disturbance, avoid frequent nest inspections, tropical species require consistent warmth, cold temperatures can be fatal, wild-caught colonies may have parasites, quarantine and monitor closely, nest substrate must stay moist to match their natural habitat

Nest Preferences

In the wild, Pristomyrmex schoedli nests in fallen logs and decaying wood on the forest floor. Colonies are often concentrated in logs, as about 100 workers were collected from a single log within 10 minutes ^[1]. For captive care, provide a nest that mimics this, such as Y-tong or plaster with embedded wood pieces. Maintain consistent moisture in the nest material to reflect their damp habitat ^[1].

Feeding and Diet

These ants are omnivorous, likely feeding on small arthropods and honeydew, as workers forage on leaves ^[1]. In captivity, offer small live prey like fruit flies or pinhead crickets, along with sugar sources like diluted honey. Feed protein prey 2-3 times per week and keep sugar water available ^[1][2].

Temperature and Care

As a tropical species, they require warm temperatures year-round. Aim for 24-28°C in the nest area, using a heating cable to create a gentle gradient ^[2]. Room temperature may suffice if consistently warm. No winter cooling is needed ^[2].

Behavior and Temperament

Workers are diurnal, foraging on leaves during the day, which is unusual for Pristomyrmex ^[1]. They are not aggressive and use a smear defense mechanism rather than stinging. Their small size means escape prevention is essential ^[1].

Growth and Development

No specific development data exists for this species. Based on typical Myrmicinae patterns, eggs may develop into workers in 6-8 weeks at optimal temperatures. Colony growth is moderate, maxing out around 100 workers ^[1].
