Pheidole metana

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to Colombia (Meta department) and Ecuador, found in Amazonian foothill forests at 920-1100m elevation ^[1][2][3].
• Colony Type: Colony structure is unconfirmed. Based on typical Pheidole patterns, likely monogyne (single queen colonies) ^[3]. Winged queens documented in May suggest nuptial flights during rainy season ^[4].
• Size & Growth:
  • Queen: Size data unavailable
  • Worker: Size data unavailable
  • Colony: Up to several hundred workers, based on community ecology data showing this species is infrequent in the wild ^[3].
  • Growth: Moderate, inferred from typical Pheidole development patterns
  • Development: 6-8 weeks, estimated based on typical Pheidole genus development at tropical temperatures (Development time is not directly studied, inferred from related species.)
• Antkeeping:
  • Temperature: Keep warm at 24-28°C, mimicking Amazonian foothill conditions ^[3].
  • Humidity: Keep substrate consistently moist but not waterlogged, based on foothill forest environments ^[3].
  • Diapause: No, as a tropical species from low elevations, hibernation is not required.
  • Nesting: Twig-nesting species ^[3]. Use test tubes, Y-tong nests, or plaster nests with narrow chambers scaled to their small size.
• Behavior: Ground-foraging species with distinct major and minor workers. Majors may handle defense, while minors focus on foraging. Not particularly aggressive but will defend the nest. Very small size means escape prevention is critical. Foraging is likely diurnal.
• Common Issues: escape prevention is critical due to very small size, use fine mesh and tight barriers, tropical species may struggle if kept too cool, monitor temperatures, colonies may be slow to establish due to infrequent natural occurrence, wild-caught colonies may carry parasites that can harm captive populations

Housing and Nest Setup

Pheidole metana is a twig-nesting species, so adapt well to test tubes, Y-tong nests, or plaster nests ^[3]. Use narrow passages and chambers scaled to their small size. For founding, a test tube with water reservoir works well. For established colonies, ensure multiple connected chambers. Inspect all connections for gaps to prevent escapes.

Feeding and Diet

Like most Pheidole, they are omnivorous. Offer small insects, protein jelly, and sugar sources like honey water. Feed protein 2-3 times per week and keep sugar available. Remove uneaten prey after 24-48 hours to prevent mold.

Temperature and Seasonal Care

Maintain 24-28°C, reflecting their warm habitat ^[3]. Use a gentle gradient with a heating cable if needed. Avoid temperatures below 20°C. As a tropical species, no hibernation is required, but reduced activity in cooler months may occur.

Colony Establishment and Growth

Colonies start with a queen who likely seals herself in a chamber to raise the first brood. Growth is moderate, reaching up to several hundred workers over time ^[3]. Patience is key, as colonies may establish slowly.

Escape Prevention

Critical due to very small size. Use fine mesh barriers and fluon on all edges. Check test tube lids and nest seams carefully for gaps.
