Pheidole purpurea

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Mesophyl forest in Chiapas, Mexico, from sea level to nearly 1700m elevation ^[1][2]. Also found in Guatemala and Honduras ^[3].
• Colony Type: Unconfirmed, likely monogyne based on typical Pheidole patterns, but colony structure has not been directly documented for this species.
• Size & Growth:
  • Queen: ~6-8mm, inferred from Pheidole genus
  • Worker: Minor workers: ~2-3mm, Major workers: ~3-5mm, inferred from Pheidole genus
  • Colony: Up to several thousand workers, estimated based on related species
  • Growth: Moderate, estimated
  • Development: Estimated 6-8 weeks at optimal temperature based on typical Pheidole development (Development time is estimated, no specific data available for this species.)
• Antkeeping:
  • Temperature: Keep warm and stable, roughly low-to-mid 20s°C, based on their tropical habitat ^[1].
  • Humidity: Keep the nest substrate consistently moist but not waterlogged, as they inhabit mesophyl forests ^[1].
  • Diapause: No, this is a tropical species from Chiapas, so no diapause required.
  • Nesting: In nature, they nest beneath stones in moist soil ^[1]. For captivity, use soil-based or Y-tong nests with damp substrate.
• Behavior: They are active ground-foragers that recruit rapidly to food sources ^[1]. Not aggressive toward keepers, but major workers can bite if handled. Escape risk is high due to small size, use fine mesh barriers and tight-fitting lids.
• Common Issues: escape prevention is critical due to their small size, they can squeeze through tiny gaps, limited species-specific care information means some trial and error may be needed, humidity control is important, too dry and colonies may struggle, too wet can cause mold, wild-caught colonies may carry parasites that can devastate captive colonies, slow founding phase, queens may take months to produce first workers

Housing and Nest Setup

Pheidole purpurea does well in naturalistic setups that mimic their forest floor habitat. In the wild, they nest beneath stones in moist soil ^[1], so a soil-based formicarium or a Y-tong nest with damp substrate works well. The nest should have chambers sized appropriately for their colony size. Provide a water tube connected to the nest for humidity and drinking water. Because they are small ants, escape prevention is critical, use tight-fitting lids and fine mesh barriers on any outworld connections.

Feeding and Diet

Pheidole purpurea is an omnivorous forager that readily recruits workers to food baits in the wild ^[1]. In captivity, offer a varied diet: protein sources like small insects (e.g., fruit flies, pinhead crickets), and sugar sources like honey water or sugar water. Major workers help process larger prey items. Feed protein 2-3 times per week and keep sugar water available constantly. Remove uneaten food after 24-48 hours to prevent mold.

Temperature and Humidity

As a tropical species from Chiapas, Mexico, P. purpurea prefers warm, moderately humid conditions. Keep the nest area at roughly low-to-mid 20s°C to support normal activity ^[1]. For humidity, keep the substrate moist but not waterlogged, as they inhabit mesophyl forests ^[1]. A water tube connected to the nest helps maintain humidity.

Colony Development and Growth

Pheidole colonies start slowly, the queen raises the first brood alone. Expect 6-8 weeks from egg to first worker under optimal conditions, though this is estimated based on genus patterns. The first workers are nanitics, and subsequent broods produce normal-sized workers. Major workers develop from larvae that receive more food. A mature colony can contain several thousand workers.

Behavior and Foraging

This is an active, diurnal forager that searches for food on the ground surface. They use chemical trails to recruit nestmates, when you place food in the outworld, you'll quickly see a trail of workers forming. Major workers are often recruited for larger food items ^[1]. They are not particularly aggressive but major workers can bite if threatened.
