Pheidole simonsi

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to Central America, found in moist to wet tropical forests from Mexico through Costa Rica to Panama, with recent records extending to Colombia. Elevational range from sea level to 800m ^[1][3].
• Colony Type: Unconfirmed, no specific data on queen number or social structure.
• Size & Growth:
  • Queen: ~6-7mm, inferred from Pheidole genus patterns
  • Worker: Minor workers ~2-3mm, major workers ~4-6mm, inferred from Pheidole genus patterns
  • Colony: Colony size data unavailable
  • Growth: Moderate, inferred from tropical Pheidole species
  • Development: Unknown, no specific data available for this species (Based on related Pheidole species, development may take 6-10 weeks under optimal conditions, but this is estimated.)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, as inferred from tropical habitat ^[1].
  • Humidity: Keep substrate consistently moist but not waterlogged, as they inhabit moist forests ^[3].
  • Diapause: No, tropical species do not require diapause.
  • Nesting: Soil-nesting species, provide deep substrate (5-10cm) and dark, humid chambers ^[3].
• Behavior: These ants are active foragers with a strong recruitment system. Minor workers scout for food and recruit nestmates ^[4]. They are not aggressive toward keepers but majors can deliver a mild sting if handled. Minor workers are small, so escape prevention should focus on fine mesh barriers. They accept both protein foods and seeds ^[4].
• Common Issues: high humidity needs can lead to mold if ventilation is poor, balance is key., tropical species will be stressed by temperatures below 20°C, keep warm year-round., major workers with large heads may have difficulty navigating narrow tubes, provide wider foraging areas., seed-storing behavior means they may ignore fresh protein if well-fed, vary their diet., colonies may be slow to establish during founding phase, patience is essential.

Housing and Nest Setup

Pheidole simonsi is a soil-nesting ant that naturally excavates nests about 10cm deep in forest floor soil ^[3]. In captivity, use naturalistic setups with deep soil layer or formicariums for ground-nesting species. Y-tong nests with soil or plaster inserts work well. Provide dark, humid nest chambers ^[3]. A small outworld connected to the nest allows for foraging. Because majors have large heads, ensure passages are wide enough ^[1].

Feeding and Diet

This species is omnivorous with a flexible diet. In the wild, they store seeds in their nests, showing granivorous tendencies, but they also actively hunt protein and recruit to various food baits ^[4]. In captivity, offer protein sources like small crickets or mealworms 2-3 times per week, along with sugar sources like honey water. Seeds can be offered as enrichment. Remove uneaten protein after 24-48 hours to prevent mold.

Temperature and Humidity

As a tropical species, P. simonsi requires warm, humid conditions. Keep temperatures around 24-28°C, avoid dropping below 20°C ^[1]. Humidity should be maintained with consistently damp substrate ^[3]. A water reservoir can help maintain moisture.

Colony Development and Growth

No specific data on colony development for P. simonsi. Based on related Pheidole species, colonies may grow moderately, but size and timeline are unknown.
