Pheidole sarawakana

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Lowland rainforests of Southeast Asia (Borneo, Indonesia, Malaysia, Philippines, Thailand), nesting in rotting wood blocks ^[3][1][2].
• Colony Type: Based on Pheidole genus patterns, likely monogyne (single queen colonies) ^[3].
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements in research context
  • Worker: Major: 1.9-2.2 mm, Minor: 1.3-1.6 mm total length ^[3]
  • Colony: Up to several hundred workers, inferred from Pheidole genus patterns
  • Growth: Moderate
  • Development: Estimated 6-8 weeks based on related Pheidole species ^[3] (Development is temperature-dependent, warmer conditions speed up growth)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical lowland habitat ^[3]
  • Humidity: Keep nest substrate consistently moist but not waterlogged, mimicking humid forest environments ^[3]
  • Diapause: No, tropical species from Southeast Asia do not require hibernation ^[3]
  • Nesting: Y-tong (AAC) nests, plaster nests with wood inserts, or naturalistic setups with rotting wood pieces ^[3]
• Behavior: Generalist foragers that search for seeds, small insects, and sugar sources. Majors defend the colony and crack seeds. Not aggressive toward humans but will defend if threatened. Small size (under 2.5 mm) requires careful escape prevention ^[3].
• Common Issues: high humidity needs can lead to mold if ventilation is poor, balance with adequate airflow, small founding colonies are vulnerable to stress and disturbance, tiny size makes escape prevention critical, use fine mesh and tight barriers, rotting wood nests can dry out quickly, monitor moisture regularly, wild-caught colonies may carry parasites that can harm captive colonies

Nest Preferences

In the wild, Pheidole sarawakana nests in rotting wood blocks in lowland rainforests ^[3]. For captivity, use Y-tong (AAC) nests or plaster nests with wood inserts to mimic humid, dark conditions. Maintain consistent humidity without waterlogging. Avoid dry conditions or direct sunlight ^[3].

Feeding and Diet

This species is a generalist feeder. Offer protein sources like fruit flies or mealworms 2-3 times per week, and keep sugar water available constantly. Seeds are appreciated but not essential. Remove uneaten prey after 24-48 hours to prevent mold ^[3].

Temperature and Care

As a tropical species, keep temperatures around 24-28°C for optimal brood development. Use a heating cable on one side of the nest to create a gradient. Avoid air conditioning vents or dry rooms ^[3].

Behavior and Temperament

Active foragers that search ground and vegetation. Majors defend and crack seeds, while minors handle foraging and brood care. Not aggressive toward humans, may retreat when threatened. Small size requires excellent escape prevention with fine mesh and barriers ^[3].

Colony Founding

Founding behavior is unconfirmed. If queens are claustral, they would seal themselves in and raise first workers on stored fat reserves. Disturb founding chambers as little as possible ^[3].

Growth and Development

Colonies grow moderately. First workers may emerge in 6-8 weeks under warm conditions. Growth accelerates after initial workers, but maximum colony size is unknown, inferred to several hundred workers from genus patterns ^[3].
