Pheidole wallacei

Quick Summary

• Difficulty: Expert
• Origin & Habitat: Neotropical region, Brazil (Rondônia, Rio Madeira), Colombia (Amazonas), and French Guiana. Found in Brazilian savanna (Cerradão/Cerrado) and plateau rainforest habitats ^[1][2][3].
• Colony Type: Colony structure is unconfirmed. Pheidole species are typically monogyne (single queen), but this has not been documented for P. wallacei specifically.
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements in literature.
  • Worker: Workers consist of majors and minors with distinct morphologies, body size data unavailable.
  • Colony: Unknown, typical Pheidole colonies can reach hundreds to thousands of workers, but no data for this species.
  • Growth: Unknown
  • Development: Unconfirmed, estimated 6-10 weeks based on tropical Pheidole species at warm temperatures. (No direct data, estimates based on genus patterns.)
• Antkeeping:
  • Temperature: Aim for 24-28°C based on tropical habitat ^[2].
  • Humidity: Keep substrate consistently moist but not waterlogged, based on rainforest and savanna origins ^[2][3].
  • Diapause: No, tropical species do not require hibernation.
  • Nesting: Based on field observations nesting in soil and trees ^[2], provide naturalistic setups with soil or plaster nests. Ensure humidity gradient and escape prevention for small workers.
• Behavior: Pheidole wallacei likely has typical Pheidole behavior: defensive when threatened but not unusually aggressive. Escape risk is moderate due to small minor workers.
• Common Issues: lack of documented biology makes proper care difficult, maintaining tropical humidity can be challenging, colony establishment may be slow due to unknown founding requirements, wild-caught colonies may have parasites, difficulty obtaining this species as it is rarely kept

Species Identification and Morphology

Pheidole wallacei is a distinctive species within the 'jujuyensis complex' of the fallax group. Major workers have large heads and reddish-yellow coloration, while minor workers are smooth and shiny with a neck-like occiput. Description based on Wilson (2003) ^[4].

Natural Distribution and Habitat

This species occupies a broad but fragmented range across northern South America. The type locality is Rio Madeira in Rondônia, Brazil, and records include Amazonas in Colombia and multiple locations in French Guiana ^[1]. In Brazil, it is found in Cerradão and Cerrado habitats, occupying both soil and arboreal niches. In French Guiana, specimens have been collected from plateau forest environments ^[2][3].

Nest Preferences and Housing

Field data indicates P. wallacei nests in both soil and arboreal locations in its native habitat ^[2]. For captive care, provide naturalistic setups with soil substrate or plaster nests. Ensure a humidity gradient and escape prevention for small minor workers.

Feeding and Diet

As a Pheidole species, P. wallacei likely has an omnivorous diet typical of the genus. In captivity, offer varied diet including small insects, seeds, and sugar sources. Feed protein sources 2-3 times per week and maintain constant sugar water supply.

Temperature and Seasonal Care

Pheidole wallacei originates from tropical regions, suggesting warm temperature requirements. Aim for temperatures in the 24-28°C range based on habitat observations ^[2]. A heating cable can create a gradient for self-regulation.

Challenges and Considerations

The primary challenge is the lack of documented biological information specific to this species ^[4]. This makes P. wallacei suitable only for experienced antkeepers who can adapt care based on colony behavior.
