Pheidole charazana

Quick Summary

• Difficulty: Hard
• Origin & Habitat: Only known from Cundinamarca, Colombia, specifically Chipaque in Charaza municipality. Found in montane cultivated fields under rocks ^[1][2].
• Colony Type: Colony structure is unconfirmed. No specific data on queen number or social structure.
• Size & Growth:
  • Queen: Size data unavailable ^[3]
  • Worker: Size data unavailable ^[3]
  • Colony: Unknown, no colony size data exists ^[3]
  • Growth: Unknown
  • Development: No specific data, but typical Pheidole development takes 4-8 weeks at tropical temperatures ^[3] (This species is only known from the type series, so no captive breeding data exists.)
• Antkeeping:
  • Temperature: Based on montane Colombian origin, likely prefers moderate temperatures around 20-26°C. Avoid extremes ^[1].
  • Humidity: Found under rocks suggests variable moisture. Keep nest substrate moderately moist with some dry areas ^[3].
  • Diapause: Unknown, no data on seasonal behavior.
  • Nesting: In wild, nests under rocks. For captivity, test tube setups for founding, then Y-tong or plaster nests with small chambers ^[3].
• Behavior: Pheidole species have majors and minors, majors handle defense and seed processing, minors forage and care for brood. This species is small and not aggressive. Escape risk is moderate due to small size ^[3].
• Common Issues: very limited species-specific information means care is based on genus-level estimates., as a rarely kept species, established colonies may be difficult to find., small size makes colonies vulnerable to stress, handle gently., wild-caught colonies may carry parasites or diseases., temperature sensitivity is unknown, start moderate and observe.

Species Overview

Pheidole charazana is a recently described species known only from its original collection in the Colombian Andes. It belongs to the flavens group, a collection of small, typically yellow Pheidole species. The species has distinctive features including projected frontal lobes and rugoreticulae on the scrobes and humeri. It has never been found again since its original description, making it one of the rarest ants in the hobby. The type locality is in Cundinamarca at moderate elevation, suggesting a preference for cooler, montane conditions ^[2][1].

Housing and Nesting

For founding colonies, a standard test tube setup works well. Fill a test tube one-third with water, plug with cotton, and place the queen in the humid chamber. Founding behavior is unconfirmed for this species, so monitor closely. Once the first workers emerge and the colony grows, you can move to a formicarium. A Y-tong nest or plaster nest with small chambers works best for this tiny species. Avoid large, open spaces, they prefer tight chambers scaled to their body size ^[3].

Feeding and Diet

Pheidole species are generalist omnivores. You can feed protein sources like small insects, and carbohydrate sources including sugar water or honey. Major workers have specialized mandibles for seed processing, so they may accept small seeds, but protein should form the primary diet. Feed small prey items 2-3 times per week, and keep a constant sugar water source available. Remove uneaten prey after 24 hours to prevent mold ^[3].

Temperature and Seasonal Care

Based on its origin in the Colombian highlands, this species likely prefers moderate temperatures. Aim for 20-26°C, which is typical room temperature. Avoid temperatures above 30°C or below 15°C. Since it's from a montane region, it may experience seasonal changes, but true hibernation is unlikely. During winter, reduce feeding and allow slightly cooler temperatures. Monitor colony activity and adjust as needed ^[1].

Behavior and Colony Structure

Like all Pheidole species, this ant has two worker castes: majors and minors. Majors handle seed processing, colony defense, and food storage, while minors handle foraging, brood care, and general tasks. The species is not known to be aggressive toward keepers. Colonies likely reach several hundred workers over time, though no specific data exists. Expect major workers to appear once the colony reaches moderate size ^[3].
