Pheidole amazonica

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Amazon basin in Peru and Ecuador, from terra firme forest into seasonally flooded forest, at elevations of 200-600 m ^[1][2].
• Colony Type: Monogyne colonies with a single queen ^[1].
• Size & Growth:
  • Queen: Size data unavailable
  • Worker: Size data unavailable
  • Colony: Up to several hundred workers ^[1]
  • Growth: Moderate, inferred from tropical Pheidole patterns ^[1]
  • Development: Estimated 5-8 weeks at tropical temperatures, based on typical Pheidole development ^[1] (Development time may vary with temperature.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. As a tropical species, they prefer warm conditions. Provide a gentle gradient with heating on one side
  • Humidity: Keep nest substrate consistently moist but not waterlogged, with a humidity gradient
  • Diapause: No, tropical species do not require hibernation
  • Nesting: Twig-nesting species. Use small nests with narrow chambers, such as Y-tong or test tubes with appropriate sizing ^[2][1]
• Behavior: These ants are ground-foraging and forage very close to their nest (within 0.5 meters). Major workers are active foragers, comprising over 11% of foragers. They are not aggressive but can sting if provoked, though the sting is not medically significant. Escape risk is moderate due to small size ^[2][1].
• Common Issues: low flood tolerance, avoid waterlogging the nest ^[2], require warm temperatures year-round, cool temperatures can be fatal, small size increases escape risk, use fine mesh barriers, twig-nesting behavior requires appropriately sized nests to prevent stress

Housing and Nest Preferences

Pheidole amazonica is a twig-nesting species, meaning in the wild they colonize small decaying branches, rotting seed pods, and palm seeds on the forest floor. In captivity, use small nests with narrow chambers, such as Y-tong nests or test tubes with appropriately sized compartments. Provide a small outworld connected to the nest for foraging, but since they forage close to the nest, a large area is not needed ^[2][1].

Feeding and Diet

In the wild, Pheidole amazonica forages for small insects, honeydew, and other protein sources. No seed caches were found in field studies, so they do not store seeds. In captivity, offer small protein like fruit flies or mealworm pieces 2-3 times per week, along with sugar water or honey. Place food near the nest entrance since they forage close by ^[2][1].

Temperature and Humidity

As a tropical Amazon species, keep the nest at 24-28°C year-round. Use a heating cable on one side to create a gentle gradient, but avoid overheating. Humidity should be high, keep the substrate moist but not waterlogged, with a humidity gradient to mimic their natural habitat. ^[1]

Colony Structure and Castes

Colonies are monogyne with a single queen. They grow to several hundred workers, including minor workers and major workers. Major workers make up over 11% of foragers, which is unusual for Pheidole species. During founding, the queen likely seals herself in a chamber, but founding behavior is unconfirmed ^[2][1].

Behavior and Foraging

These ants are ground-foraging and forage very close to their nest, typically within 0.5 meters. Major workers are active foragers, comprising over 11% of foragers at baits. They are not aggressive but can sting if provoked. Escape risk is moderate due to their small size, so ensure tight-fitting lids ^[2][1].
