Pheidole leonina

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Amazon basin in South America, terra firme forest in Peru, Brazil, and Colombia ^{[1][2][3][4][5][6]}.
• Colony Type: Based on Pheidole genus patterns, likely monogyne (single queen).
• Size & Growth:
  • Queen: Estimated ~7-9 mm based on related Pheidole species.
  • Worker: Estimated ~2-3 mm for majors and ~1-2 mm for minors based on genus patterns.
  • Colony: Up to several hundred workers, estimated based on genus patterns.
  • Growth: Moderate
  • Development: Estimated 6-8 weeks at optimal temperature based on related species. (Development time may vary with temperature and feeding.)
• Antkeeping:
  • Temperature: Keep warm around 24-28°C, as they are tropical ants.
  • Humidity: Keep substrate consistently moist but not waterlogged, based on terra firme forest conditions.
  • Diapause: No, as a tropical species, they do not require hibernation.
  • Nesting: Start with a test tube setup for founding colonies. Once established, use Y-tong or plaster nests with tight chambers.
• Behavior: These ants are active foragers that recruit nestmates to food sources, as observed in the wild ^[7]. Minor workers are very small, so escape prevention is critical. They are not aggressive but will defend their nest.
• Common Issues: tiny minor workers mean escape prevention is critical, they can squeeze through standard barriers., humidity control is important, too wet causes mold, too dry stresses the colony., tropical species cannot tolerate cool temperatures, keep consistently warm., slow colony establishment may cause keepers to overfeed or disturb the nest too often., limited available information means some care aspects are estimates based on genus patterns.

Nest Preferences

In the wild, Pheidole leonina nests in soil or under stones in terra firme Amazon forest environments ^[7]. They prefer damp but well-drained substrate conditions. For captive care, start with a simple test tube setup for the founding queen. Once the colony reaches 20-30 workers, you can move them to a formicarium. Y-tong or plaster nests work well for this species. They prefer tight chambers and narrow passages scaled to their tiny minor workers.

Feeding and Diet

Pheidole leonina is omnivorous with a preference for protein. In their natural habitat, they recruited to dead cockroach, showing they readily accept protein sources ^[7]. Feed them small insects like fruit flies, pinhead crickets, or mealworms. They also likely consume honeydew and can accept sugar water or honey occasionally. Major workers can process harder foods with their enlarged heads. Feed protein 2-3 times per week and provide a constant sugar source.

Temperature and Care

As a tropical Amazon species, Pheidole leonina requires warm temperatures around 24-28°C. They cannot tolerate cool conditions and may become sluggish below 22°C. Use a heating cable on one side of the nest to create a temperature gradient. Maintain humidity by keeping the nest substrate moderately moist but not waterlogged. Since they come from a tropical environment, they do not require diapause or hibernation.

Behavior and Temperament

This species shows typical Pheidole behavior with distinct major and minor castes. Minor workers are tiny foragers while majors defend the colony and help process food. They recruit nestmates to food sources through chemical trails, as observed with their recruitment to dead cockroach in the wild ^[7]. They are not particularly aggressive but will bite if threatened. The main concern for keepers is their very small minor workers, they can escape through standard barriers.

Colony Growth and Development

Pheidole leonina follows the typical Pheidole colony development pattern. The claustral queen seals herself in a chamber and raises the first brood alone using stored fat reserves. First workers are typically smaller than normal workers. Colony growth is moderate, expect several months to reach 50 workers, with faster growth once the first major workers appear. Based on related species, the colony may reach several hundred workers over 1-2 years.
