Pheidole excellens

Quick Summary

• Difficulty: Medium
• Origin & Habitat: West Africa, Ghana, Guinea, Ivory Coast, and Togo. Found in savanna zones, forest margins, and urban green spaces ^[2][3][1].
• Colony Type: Based on typical Pheidole genus patterns, likely monogyne (single queen colonies).
• Size & Growth:
  • Queen: Size data unavailable, inferred from Pheidole genus patterns (~6-8mm)
  • Worker: Size data unavailable, inferred from Pheidole genus patterns (minor workers likely 2-3mm, majors 4-5mm)
  • Colony: Up to several hundred workers, estimated based on related species
  • Growth: Moderate, based on typical Pheidole development patterns
  • Development: Estimated 6-8 weeks at optimal temperatures, inferred from genus patterns (Development is temperature-dependent, warmer conditions accelerate growth)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical habitat inference.
  • Humidity: Keep substrate consistently moist but not waterlogged, based on habitat inference.
  • Diapause: No, tropical species, no hibernation needed.
  • Nesting: In wild, nests in soil and rotting wood, in captivity, Y-tong or plaster nests are suitable.
• Behavior: Pheidole excellens is an opportunistic forager, collecting seeds and small insects. Major workers help with food processing and defense. They are not aggressive toward keepers but will defend the nest. Escape prevention is important due to small size.
• Common Issues: consistent warmth is needed, cold temperatures below 20°C can slow brood development, wild-caught colonies may harbor parasites, quarantine and observe new colonies carefully, seed-eating diet requires appropriate food, offer grass seeds alongside protein, sensitive to habitat disturbance, avoid placing nests in areas prone to fires or temperature fluctuations, colonies can be slow to establish, patience is needed during the founding phase

Housing and Nest Setup

For founding colonies, a simple test tube setup works well, fill a test tube with water, plug with cotton, and place the queen in a dark area. Once the colony reaches 20-30 workers, consider moving to a more spacious formicarium. Y-tong (AAC) nests are excellent for this species as they provide appropriately scaled chambers. Plaster nests also work well, providing stable humidity. For the outworld, use a simple container with a substrate layer where workers can forage. Ensure escape prevention is in place, use Fluon on the rim of the outworld container.

Feeding and Diet

As an opportunist species, Pheidole excellens accepts a varied diet. Related African Pheidole species are primarily granivorous, harvesting seeds from grasses ^[5]. In captivity, offer a mix of seeds (grass seeds, millet, chia) as a staple food source, along with protein sources like small insects. They will also accept sugar water or honey as an energy source. Feed seeds continuously and offer protein 2-3 times per week.

Temperature and Seasonal Care

This West African species requires warm conditions year-round. Maintain temperatures between 24-28°C in the nest area. A heating cable placed on one side of the nest creates a temperature gradient. Avoid temperatures below 20°C for extended periods as this can slow brood development. Unlike temperate species, they do not require a diapause period.

Colony Development and Growth

The claustral queen seals herself in a chamber and raises the first brood using stored fat reserves. First workers (nanitics) emerge after 6-8 weeks at optimal temperature. Once nanitics emerge, colony growth accelerates. Major workers appear as the colony grows to help with food processing and defense. Expect the colony to reach several hundred workers over 1-2 years under good conditions.

Behavior and Defense

Workers are active foragers that search for seeds and small prey. Major workers assist with processing hard seeds and defend the nest against intruders. When the nest is disturbed, majors will rush to defend while minors evacuate brood. They are not particularly aggressive toward humans and rarely sting. Their sting is mild and not medically significant, as typical for Myrmicinae ants.
