Pheidole diana

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Central America, forest floor habitats ^[1]
• Colony Type: Likely monogyne based on Pheidole genus patterns, but unconfirmed for this species ^[1]
• Size & Growth:
  • Queen: Size data unavailable, but inferred from Pheidole genus to be around 6-8 mm
  • Worker: Inferred to be 2-4 mm based on Pheidole genus ^[1]
  • Colony: Up to several hundred workers ^[1]
  • Growth: Moderate, inferred from genus patterns
  • Development: Estimated 6-8 weeks at optimal temperature, inferred from Pheidole genus ^[1] (Development time may vary with temperature and feeding conditions.)
• Antkeeping:
  • Temperature: Keep at 22-26°C, based on general Pheidole care ^[1]
  • Humidity: Maintain moderate humidity, keep substrate consistently moist but not waterlogged ^[1]
  • Diapause: No, as a Central American species, inferred from range ^[1]
  • Nesting: Use test tube setup for founding colonies, upgrade to Y-tong or plaster nests with narrow chambers once established ^[1]
• Behavior: Pheidole diana can sting, but it is less medically significant to humans. Workers are generally calm and may flee from threats rather than confront. Escape prevention is critical due to their small size ^[1].
• Common Issues: escape prevention is critical, their small size allows them to squeeze through tiny gaps, overfeeding can lead to mold problems in nest setups, slow founding phase may cause keepers to abandon colonies prematurely, test tube flooding can kill founding queens, use appropriate water reservoir size, granivorous diet requires seeds to be available, not just protein

Nest Preferences and Setup

Pheidole diana thrives in enclosed, dark nest spaces that mimic their natural forest floor habitat. For founding colonies, a simple test tube setup works well, fill one end with water trapped by a cotton plug, leaving the dry end for the queen ^[1]. Once the colony reaches 100+ workers, upgrade to a Y-tong or plaster nest with narrow passages, as Pheidole prefer tight spaces over open areas ^[1]. A small outworld connected to the nest allows for foraging and waste disposal.

Feeding and Diet

Pheidole diana is primarily granivorous, so provide a constant supply of small seeds like sesame or millet ^[1]. Soldiers stay in the nest to crack seeds using their powerful mandibles. Offer protein sources 2-3 times per week, such as small insects or fruit flies ^[1]. Sugar water or honey can be offered occasionally, but seeds should form the dietary foundation. Always remove uneaten protein within 24 hours to prevent mold.

Temperature and Seasonal Care

Maintain temperatures between 22-26°C for optimal colony health ^[1]. This species does not require hibernation as it comes from Central America. Room temperature within this range is typically sufficient. If your home runs cooler, a heating cable placed on top of the nest can provide warmth ^[1]. Avoid temperatures below 15°C or above 30°C to prevent stress.

Behavior and Colony Dynamics

Pheidole colonies develop distinct castes, minor workers handle foraging and nest maintenance, while major workers (soldiers) specialize in seed-crushing and defense ^[1]. Workers are non-aggressive and will retreat from threats. They communicate through chemical signals and use tandem running to recruit nestmates to food sources. Major workers typically appear after the colony reaches several dozen workers.
