Pheidole lineafrons

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Cloud forest in Costa Rica (Monteverde, Puntarenas) at 1480m elevation, and recently documented in Colombia (Caldas) at 1610m. Nests in clay banks, typically in disturbed areas like landslide scars in mature forest ^[1][2].
• Colony Type: Based on typical Pheidole patterns, likely monogyne with single queen colonies.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Pheidole genus that queens are typically small
  • Worker: Size data unavailable, minor and major workers are small, but exact body measurements not provided
  • Colony: Colonies can grow to several hundred workers, estimated from genus patterns
  • Growth: Moderate
  • Development: Estimated 6-8 weeks at optimal temperature based on related Pheidole species (Development timeline not directly studied, estimate based on genus patterns for tropical ants)
• Antkeeping:
  • Temperature: Keep around 22-26°C, inferred from cloud forest habitat ^[1]
  • Humidity: High humidity required, keep nest substrate consistently moist but not waterlogged ^[1]
  • Diapause: No, tropical species do not require hibernation ^[1]
  • Nesting: Y-tong (AAC) or plaster nests work well, provide tight chambers scaled to small size ^[1]
• Behavior: Nocturnal foragers, expect activity in evening and night hours ^[1]. Typical Pheidole behavior with majors defending nest and minors handling foraging. Escape risk is moderate due to small size, use standard barrier precautions.
• Common Issues: high humidity needs can lead to mold if ventilation is poor, nocturnal activity means less visible during daytime, don't mistake for colony failure, small workers can escape through standard barriers if gaps exist, cloud forest origin means they may struggle in warm, dry rooms, limited availability as a newly described species, may be difficult to acquire

Housing and Nest Setup

Pheidole lineafrons is a small ant that does well in Y-tong (AAC) nests or plaster formicaria. Provide chambers scaled to their tiny size, minor workers are very small, so tight-fitting connections are important. Because they come from cloud forest habitat, they need higher humidity than typical room-temperature ants. A water tube connected to the nest works well for hydration ^[1]. For the outworld, a simple setup with a small foraging area is sufficient. Escape prevention should be moderate, use a standard barrier of fluon on the rim of the outworld ^[1].

Feeding and Diet

These ants are omnivorous and will accept a variety of foods. Protein sources like small insects should be offered regularly, twice weekly is a good starting point. Sugar water, honey, or diluted maple syrup should always be available in the outworld. In the wild, minor workers were observed recruiting to bait, suggesting they readily discover food sources ^[1]. Remove uneaten food after 24-48 hours to prevent mold.

Temperature and Humidity

This species comes from high-elevation cloud forest, so it prefers cooler conditions. Aim for 22-26°C, avoid placing the nest near heat sources or in direct sunlight ^[1]. Humidity should be kept high, the nest substrate should feel consistently moist but never waterlogged. A good approach is to keep one side of the nest slightly drier so the ants can choose their preferred humidity zone.

Colony Development and Growth

Pheidole lineafrons has the classic two-caste system: minor workers handle most tasks while major workers defend the nest and help process large food items ^[2]. Specific development times are not documented, but based on related species, expect 6-8 weeks from egg to first worker. Colonies likely reach several hundred workers at maturity. This is a nocturnal species, so expect most activity during evening and night hours ^[1].

Seasonal Care

As a tropical cloud forest species, Pheidole lineafrons does not require a true hibernation or diapause period. During cooler months, activity may reduce, which is normal. Maintain stable temperatures year-round (22-26°C) and monitor humidity closely during dry seasons ^[1].
