Pheidole scimitara

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Amazon Basin in Peru (Madre de Dios) and Brazil (Amazonas, Pará states) at low elevations around 400m, inhabiting tropical floodplain forests ^[4][5][2].
• Colony Type: Unconfirmed, no specific studies document queen number or social structure.
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements in described material
  • Worker: Size data unavailable, no total length measurements in described material
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unknown, no direct measurements. Based on typical Pheidole patterns in tropical conditions, estimate 6-10 weeks from egg to first worker at optimal temperatures. (Development may vary with temperature and colony conditions.)
• Antkeeping:
  • Temperature: Aim for 24-28°C, typical for Amazonian species. Use a heating cable to create a gradient if needed.
  • Humidity: Keep substrate consistently moist but not waterlogged, similar to a damp forest floor.
  • Diapause: Unknown, tropical species may not require true diapause, but some seasonal slow-down may occur.
  • Nesting: Natural nesting behavior is unconfirmed. Based on Pheidole genus, likely nest in soil. Use test tube setups for founding colonies and Y-tong or plaster formicaria for established colonies.
• Behavior: Behavior is unstudied. Escape prevention should be moderate due to small size. Defense mechanisms are unconfirmed, but as a Myrmicinae, they likely have a sting.
• Common Issues: small size increases escape risk, ensure tight lids on outworld, lack of species-specific data may lead to improper care, monitor colony closely, humidity management is critical for tropical species, avoid mold by proper ventilation, growth rate is unknown, adjust feeding based on colony activity

Appearance and Identification

Pheidole scimitara is striking due to its very long propodeal spines. Major workers have medium to dark reddish-brown heads and mandibles with light yellowish-brown bodies, while minors are yellow with light yellowish-brown heads and gasters. The species has extremely large eyes and antennal scapes that extend beyond the occipital corner in majors. Size data is unavailable, but it belongs to the diligens group, distinguished by these features ^[3].

Distribution and Habitat

This species is recorded across more than 2000 km of Amazonian floodplain forest ^[4]. Originally from Peru, it is now confirmed in Brazil's Amazonas and Pará states ^[5][2]. It inhabits lowland tropical forests with high humidity and warm temperatures.

Nest Preferences and Housing

Specific nesting behavior is unconfirmed. Based on Pheidole genus, they likely nest in soil with underground chambers. For captive care, start in a test tube setup with a water reservoir, keeping it humid but not flooded. Transition to a Y-tong or plaster formicarium when the colony grows. Observe your colony's behavior to adjust moisture levels.

Feeding and Diet

Diet is unconfirmed, but Pheidole genus members are typically omnivorous with preferences for seeds and small insects. Offer varied diet: protein sources like small crickets or mealworms, seeds such as millet, and sugar water. Major workers may process larger prey. Feed protein 2-3 times weekly and provide constant sugar access.

Temperature and Seasonal Care

As an Amazonian species, aim for 24-28°C with a gentle gradient using a heating cable. Humidity should be high to mimic natural habitat. Diapause is unknown, tropical species may show reduced activity in cooler months without true hibernation.

Behavior and Colony Structure

Social structure is unstudied. Pheidole genus often has distinct worker castes, but no data for this species. Escape risk is moderate due to small size. Defense mechanisms are unconfirmed, but as a Myrmicinae, they likely have a sting.
