Pheidole cordiceps

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Argentina (Neotropical region), found in multiple provinces including Buenos Aires, Córdoba, Mendoza, and Salta ^[1]. Habitat includes forest edges and disturbed areas based on abundance in fragmented forests ^[2].
• Colony Type: Likely monogyne (single queen) based on typical Pheidole patterns, but unconfirmed for this species.
• Size & Growth:
  • Queen: Size data unavailable for body length ^[1]
  • Worker: Size data unavailable for body length ^[1]
  • Colony: Estimated up to low thousands of workers based on genus patterns ^[2]
  • Growth: Unknown, estimated Moderate based on genus patterns
  • Development: Estimated 6-8 weeks at optimal temperature (25-28°C) based on typical Pheidole development patterns (Development time is estimated from genus patterns, no specific studies exist for this species)
• Antkeeping:
  • Temperature: Keep at 24-28°C (warm room temperature). Based on genus patterns for tropical/subtropical ants. A heating cable can create a gradient if needed.
  • Humidity: Moderate humidity around 50-60%. Keep the nest substrate slightly moist but allow some drying between waterings. Based on habitat in temperate-to-subtropical Argentina.
  • Diapause: Unknown for this species. Based on Argentine climate, a cool period (15-18°C) for 2-3 months during winter may be beneficial, but unconfirmed.
  • Nesting: Nests in soil in the wild ^[1]. For captivity, use Y-tong nests or test tube setups with moderate humidity.
• Behavior: Pheidole cordiceps is generally peaceful. Majors have enlarged heads for seed-cracking but rarely bite. Minors handle foraging and brood care. Workers are active foragers. Escape prevention is critical due to small minor size (0.70mm head width) ^[1].
• Common Issues: escape prevention is critical due to small minor worker size, they can squeeze through standard gaps, no specific biological data exists, keepers must rely on genus-level care assumptions, winter cooling may be stressful if done incorrectly, transition gradually, wild-caught colonies may carry parasites that can devastate captive colonies, overheating is more dangerous than underheating, avoid temperatures above 32°C

Nest Preferences

In the wild, Pheidole cordiceps nests in soil, typically in open areas or forest edges ^[1]. For captive care, a Y-tong nest works well, providing dark chambers that mimic underground conditions. Test tube setups are also suitable for founding colonies. The nest should have moderate humidity, damp but not waterlogged. Avoid nests that are too large for the colony size initially. As the colony grows, you can provide additional outworld space. The species has been found in fragmented forest habitats, suggesting it tolerates some disturbance ^[2].

Feeding and Diet

Feeding habits for Pheidole cordiceps are unconfirmed, but Pheidole ants are generally seed-harvesters with majors specialized for cracking hard seeds. They may also eat small insects and other protein sources. For captivity, offer a mix of seeds and protein sources, and sugar water occasionally. Remove uneaten food to prevent mold.

Temperature and Care

Keep Pheidole cordiceps at warm room temperature, around 24-28°C, based on genus patterns for tropical/subtropical ants. A heating cable can help if home is cooler. Never exceed 32°C, overheating is more dangerous. During winter, a cool period may be beneficial, but unconfirmed for this species.

Behavior and Temperament

Pheidole cordiceps is a peaceful species. Majors have enlarged heads for seed-cracking but rarely bite. Minors handle most tasks: foraging, caring for brood, and tending the queen. Workers are active foragers. Escape prevention is important because minors are tiny (0.70mm head width) ^[1].

Colony Founding

Colony founding behavior has not been documented for this specific species. Founding behavior is unconfirmed. Based on typical Pheidole patterns, queens may seal themselves in a claustral chamber, but this is not confirmed for Pheidole cordiceps. Do not disturb the founding chamber during this time.
